parts question guys
I've currently got shimano claris RS200 175mm cranks but I wanted to go down to 170mm. Unfortunately the standard cranks are either sold out or bloody expensive. Does anyone know if there are reasonable 3rd party alternatives. Obviously the non-drive arm looks like any crank arm but the drive arm has the specific shape to it.

White tyres good or bad?

I vaguely recall that - in tennis, at least - white overgrip (it's a plastic stripe that wraps over the grip on a tennis racquet) is to be preferred over black or any other colour, for grip reasons.

The same applies to tyres? Durability is secondary, it's for my town rider. All I care for is grip.
>>
>>1799922
Any colored tyres are shit but white ones are by far the worst. Get black only, no matter how much the missus says the white is prettier.
>>
>>1799922
when it comes to bicycle tires, black has the most grip, any other color is just a sacrifice in service of aesthetics

Tubed?

Or tubeless?


My current bike has tubed 700×38C tyres, and I've never had a puncture. But I'm considering building a road bike with 700×28C tyres. I'm wondering if it's worthwhile to go tubeless...

I've only ever had one tube puncture with my current bike, and that was as a result of a crash. But everything I keep reading about tubed road bike tyres is that you can expect to have 4 punctures a month. I've never had an ordinary puncture in 9 months!

Are the tubeless shills just that? Or is there a real advantage to going tubeless?

Tubes are fine for streets unless you plan on riding on gravel or shitty roads. Flats will always eventually happen and you should carry what you need to fix one, but 4 a month would be crazy of course. How many you get comes down to the quality of tire, keeping the pressure where it should be, and how much shit you run over.

Whats an easy way to keep a multitool on a bike? Got a small one for only 5 bucks but have no way to store it on the bike. Should I just use a rubberband or something? I feel like it would fuck up the paint bad (not that I mind that too much) or it would just bounce out eventually.

>shitty roads
Are UK roads of this quality?
The numbers of potholes and really worn down tarmac seems really prevalent.

I've had a car blow a tyre out from a hidden pothole (car had a proper spare tyre anyway, and someone in a vintage 80s Ferrari stopped to ask if any help was required, which was very unexpected), had a car tyre have a slow puncture from a large nail, that was just left in the ground - unfortunately the nuts were on too tight from the dealership, and roadside assistance was necessary to get the punctured wheel off.
Oh, and tyre wear on UK roads is fucking insane - had fuel efficient Hankook soft compound go from road legal to bald after a month of driving on a motorway for a month. Switched to hard compound Firestones, and it hardly ever wears, but fuel efficiency takes a bit of a hit.
This is a bit more of an /o/ discussion, but UK roads are borderline third world. After a decade and half of austerity, infrastructure is total garbage. Any reason why a bunch of different car reviewers hate hard suspension in sports cars???

My current bike, as I mentioned, has tubed Kenda 700×38c tyres - they're pretty good at the shit road conditions, but my bike is a heavy hybrid frame. No good for speed or hill climbing.
>>
>>1799947
A little extra money to never have to deal with square taper again is a great fucking deal. A shop could install it for you for not much (maybe free if you bought it from them) if you don't want to buy the tool.

>Are UK roads of this quality
Hahaha oh boy, I can feel my blood pressure spiking just from you mentioning them. I swear that everyone who has any kind of hand in road maintenance, financing, planning, work completion, whatever, should be forced at gunpoint to ride over them all day. The second they make a noise, lift out of the saddle or get bumped off the pedals because of the absolute state of these gravel tracks masquerading as roads they are instantly shot.

Brief history lesson (I can go on and on...): drop bars were developed to give the OPTION of an aero position, with the tops about level with the saddle to allow comfortable cruising. Over the years, many racers and wannabe racers and wannalooklike racers have shoved the bars lower and lower, so they suffer nearly all the time. Works for pros, who can train six hours a day, but it's hard for the rest of us.
Several years ago, after 30 years of trying to make my body conform to a racer's idea of how a bike should be set up, I decided to raise the bars and make the bike fit me, rather than the other way around. Instantly, I could ride 30 percent or so longer without discomfort, and my times on familiar rides went DOWN, whether because I was fitter or I didn't have to fight the bike.
Don't completely ignore the advice of the ARPs, but for ordinary humans, there are other ways to set up a bike than the one you see in the Tour de France.

Is there a way to figure out the bearing type (cup and cone or cartridge bearing) from the outside without tools? My front hub is feeling a bit rough and I would like to know what I'm going into before I start taking it apart since I haven't done hub service before.

I was unable to find anything on the hub except the brand, which is Linus (made in Taiwan, not by the Linus Bike brand). Couldn't find manufacturer data on it, probably because it's over 10 years old.

Can anybody has some clues on this sound
Happens only when i ride, no matter the gear
Happens with and without the saddle/saddle post
Its not rhythmic and it is not there when I turn the pedals with the wheels not touching the ground
I tried three different set of pedals one of wich brand new the sound is still there
I the chain doesnt seems to jump, it's not worn out and its clean and well lubricated

remove the wheel from the bike and pull that rubber boot off
it will just fit right back on after

should be apparent then

almost certainly cup and cone

Looks like a cup and cone indeed without the rubber.

Is there a standard to the ball bearings and cones or do I have to take it apart to figure out which spares I need (if it's even worth repairing, that is)?

Eh, almost all bike noises are, or can be made to be rhythmic. Are you saying you can't make the noise repeat?
In the audio clip, are you constantly pedalling (not pedalling, letting off, pedalling, letting off)?

I was implying it's not the chain rubbing on the front mech

How can you tell? As opposed to how it would somehow feel different if it was any other part of the drive train? If you're experienced enough to have developed that much of a discerning sensibility you would not need to ask a bunch of anonymous yak herders on the intertnets for advice.

I've had that same symptom form improperly mounted pedals, worn out pedal bearings, worn out bottom bracket, a bent sprocket tooth, misaligned gears and who know what other mystery causes.
I would start by remounting the pedals and making sure the pedal threads are properly greased and tightened, and work myself outward from there.

The bearings are a standard size, the cones are very specific in width, but any of close enough width will work. There’s a good website that sells every conceivable size of cone (I’m sure another anon remembers the url)

Thanks for the info. I live in Europe so the website may or may not be a good solution for me, but it could be a good reference catalog either way.

I was thinking of getting the parts out and then go for a trip through the local bike shops to see if they have the spares available. If that fails I will either try to find out if I can get the missing parts online (if I can figure out the specific parts I need) or put the old parts back in after cleaning and start looking for a set of new (or second hand) wheels. If the hub bearing surfaces are damaged I might have to look for new wheels anyway.

I have a 29 inch wheel with centrelock, it has a slightly fucked front hub from a crash.

I mostly use Shimano hubs so ymmv. I usually ebay first for NOS stuff, but I've also ordered axles, cones, etc from Wheels Mfg. They list their measurements, but a lot of their stuff has been out of stock.

I've polished cups & cones before (had a bearing crack & gouge the rear ds cup), but even if you have the right setup and know what you're doing, it's probably not worth it. There's no restoring it to 'new', it will always be a worn part.

Got this old schwinn for free at work, seems like everything works, I already have a dedicated serious mountain bike and I wanna do some egregious stuff with my new shitbike. Thinking I'm just gonna service the old schwinn Altus, throw a new chain on and some cheap road tires and use it when I go to the gas station and so forth. Might even put a solid suspension fork on it. What do you guys think? Yes I know it's a money pit

>>1799930
>adhesive foil
Don't think I've ever seen anyone use this one a bike... It will probably flake off in the long run, but if you don't mind potentially having to re-apply more foil in the future it would probably work okay.

>>1799937
The main benefit of tubeless is that it lets you run lower pressures with higher volume tires, but with relatively narrow ride tires that advantage almost disappears, the only real advantage is that sealant can fill minor punctures - the trade off is cost, so unless you already have tubeless compatible rims and tires and access to a compressor, tubes are still the way to go on the road.

>>1799944
If you don't want a bag for some reason, make a simple DIY tool roll or just use a rubber band around that multitool and your spare tube and strap those to your saddle rails or carry it in a jersey pocket.

>>1800110
As previous anon said, squats. Also core exercises are important too.

Could be a whole worse. Just ride it, and swap the tires for slicks if you're going to be on pavement all the time.

say I don't mind flaking, also say I couldn't find the blue I wanted, and I found the blue I wanted with glitter in acyrlic paint section... and started painting over the parts I want without masking tape despite having some... then painted whole bike...

now I have a bike painted in glitter blue, which I'll have paint like two more times and have it flaked off in single trip. I regret nothing but feel like I really should.

cleaning it will be a pain in the ass won't it...

Need to change my cassette/derailleur but are master link chains the meta? 2nd time this chain had one pop off
Didn't happen on my old chain which was master link
Seems like a pretty big flaw that they can fail if the chain slips
>>
>>1799930
You could get some cheapish vinyl, it's generally tough and didn't mess up any of my paint under it.
>>
>>1800200
did the master link come with the chain?
I put a kmc masterlink on a shimano chain the other day, which everyone says is fine, and there's a little play in there. I don't really trust it, whereas i've never had a kmc or sram masterlink fail on chains they came with, they fit tighter, and i've worn out dozens of them.

Shimano chains don't use masterlinks, they use special joining pins, and if you install them correctly it's max reliable, and shimano chains are very good. But it is a little bit trickier to install them, you can bend it very easily. Has to be perfectly lined up. And if you're tinkering then it's very helpful to be able to remove a chain at will.
>>
>>1800152
that's a diamondback anon.
I see no reason to throw money at it. Is that chain even stretched? Nice tires are nice but it's not like shit tires dont roll and those atleast aren't inappropriate.

First priority for a junky beater is getting a rack+basket.
You could do a rear obviously but you could also do lowrider baskets

Buy a whole new wheel. Look at german sites, they sell complete wheels with dynamo hubs and decent spec. Like Bike24, Bike-Components, Starbike. Having an lbs build you one will be more expensive.

dynamo hub is a very good idea btw. They're awesome.

If you just open them up, clean everything, and re-grease, it will make a positive improvement, even if the cones are pitted and the balls are dull.

It's not possible to do this, you'd have to remove so much material from the hub to make space for a cartridge bearing that you'd destroy the hub in the process or make it so weak that the hub would fail in use.

I own this exact bike, it's sitting in my garage. It's a 2017 diamondback sorrento. 7x3 with a decent shock up front. I rode mine for a thousand miles or so over 3 years before I bought a real road bike.

I keep saying I'm going to put different tires on it and blah blah blah but I never end up doing it. I'll never sell it because it's the bike that brought me back into cycling and I'm now 10,000 miles into it.

Oh and change the seat on that D-back, it's terrible. Just get a good cheap ergonomic seat with a cutout. I put an old selle italia seat on mine and it worked fine.

The tires are these weird xc things that work decently but are 00s tech.

used 90s mtb or hybrids are nice, sometimes you can find a nice used road bike too, look for no suspension, and good brand names like giant, gt, trek and not walmart brands like magna, huffy, mongoose. Schwinn is a mixed bag, usually its walmart tier but their older bikes were fine. if you need to carry stuff look for rack mounts, fenders are nice too. if where you live is flat you can just get a single speed.

if you are buying new just get a surly cross check or some name brand hybrid. if you can get away with a single speed, state bikes are pretty cheap, id go with their 4130 line tho and have it checked out by a shop.

If it fits you, why not just repair it to make it rideable? You don't have to do all kinds of upgrades to make that into a bike that's okay to ride, just fix it up and let your experience of riding it determine whether you want to invest in making that into a 'better' bike or not.

>>1800326
Only if you actually need the folding capabilities so you can take your bike on public transport. If you're not going to use it that way, then a standard bike that avoids all the downsides that come with all but the very best (and most expensive) folding bikes.

repairing bikes usually is really expensive up front and cheaper after youve done it for a while (since you would have already bought all the tools you need and have some spare parts lying around). Depends how much money you wanna throw into it because it would probably be cheaper to just buy a new (used) bike with less problems.

Should I convert to 650b wheels on my previously 27" bike that now has 700c wheels on it...just for fun? It already has 700c to 650 brakes on it and i have about a whole inch of room to move the pads down so I don't see why fitment would be an issue. I'm just trying to find a good reason to other than just because.
The brake tracks are pretty worn, the braking strip is pretty much gone off of the front wheel so that's one reason, but I'm unsure of the purpose that this bike would serve if I do this. gravel meme I guess? I already have other road bikes and a rigid mtb commuter, so it might serve as that middle ground.
Lately it's just been sitting without a tire because one of them picked up a 4 inch nail just destroying it and I'm not sure what I want to do with it because I quite like this frame and do not want to sell it.

It's really tough to tell if sprockets are worn out unless they're severely worn to the point they have 'shark teeth' and that freewheel doesn't look to be that point. Only way to know for sure is to install a new chain (if your current one is worn out) and see if it skips...

>>1800444
If that change will result in making that bike one that you want to ride, and it's within your budget to replace wheels and tires, go for it. Sometimes it's useful to try new things purely for the sake of the experience and knowledge you'll gain.

If I just need to git gud, then it's fine. I have a decently steep decline near my house (~8%) that I could just bomb through in my old mtb, but the road bike goes way faster, and when I needed to brake I went to the drops just to make sure I wasn't going to blow past the traffic light.
>>
>>1800494
I have a 15% short descent nearby, braking from the hoods was just enough even on the mech discs before I converted to hydro.
>>
>>1800494
Whether that's a problem or not also depends on which brakes you have. With old non-aero brakes the expectation was you'd be in the drops for hard braking, so those brakes simply aren't designed to give full power when riding on the hoods. But you could also have a mismatched setup or some kind of issue that can be corrected, so post a picture of your bike if you want a proper answer.
>>
>>1800294
Yeah, do it. A couple of my friends have tandems, and they're good fun. I'm 6'2", so I rarely get to ride stoker, but my 6'5" friend has a Burley that's the right size, and we're like a rocket on that thing. Sometimes we'll go out on the local loops, just to catch wannabe pros & flip their lids. Pass them on descents, they accept it, pass them on ascents they "can't fuckin believe it".

You guys asked for an update when I grabbed something, been enjoying it a good deal this past week. Maybe it belongs in bike buying but oh well. Happy Sunday /n/.

Competitive tandems seem exclusive to para sports - Tandems for visually impaired track cycling, time trials and road racing are all really fascinating to watch when the Paralympics come up.

Think it was the Para Cycling Time Trials when simultaneously, Women's Visually Impaired, Men's Tricycles and Men's amputees were all on the Fuji International Speedway, and the tandems were easily lapping everyone else. I suppose that might be easy if there's four legs pedalling instead of just one.
I wonder if any anons here do tandem with visually impaired individuals. I understand that para cycling teams have really strict selection programmes for pilots.
I do wonder if the wheels used on tandems are specifically strengthened to carry both risers...

hmm really? Did you soak paper towels in it and cling film them on? The other thing that works reasonably well is scrubbing with a toothbrush and wd40. I also suggest you don't worry about it.

sus your brake, that matters more, and upgrade the pads.

Neat. The shop I used to work at did some work with the VA blind rehab folks, so we would build and work on their tandems sometimes.

Used to do this annual ride, 2 days, 210 miles, several thousand riders (varies each year).

For several years I'd see this older couple on a nice tandem. Chatted with them once, and they'd been doing it for a long time (>20 years). Used to come on individual bikes until the wife's eyesight deteriorated to the point that she could no longer ride by herself. So they switched to tandem mode.

Made me realize I take it for granted. The sensation of movement, the wind in my face.

That's neat. Is it just a regular hybrid like bike or something more sporty?
>>1800711
I find that the accessibility of cycling in general is actually quite neat.
Trunk impaired individuals riding time trial tricycles is fascinating. Lower limb amputees pedalling with a prosthetic or even just with a single leg is really neat. Especially with above knee amputees, I've always wondered how they balance the crankset to enable smooth pedalling.
And then there's the handcycles. Hand cyclists are fucking built - probably super aero too.

I live in the rural nowhere, but there's a nearby bike repair shop in a repurposed barn. The mechanic is a former semi-pro, and he's worked on everything from city bikes to pro athlete time trial bikes. There's a pic on his Facebook of a triathlon tandem, and it's insane to see a carbon frame tandem.

It’s a regular hybrid like bike. Huge cassette because speed is not important and the stoker is rarely of use with regards to power.

you don't need any spare clearance at all, it will cause issues if your wheels go out of true or riding in mud or gravel otherwise its fine

actual tires size commonly fluctuates ±3mm, gp4k run oversize, gp5k run undersize, most schwalbe tires run undersize and more recent tires generally tend to run undersize as they're designed for meme wide rims.

Measure it. Use a fucking ruler/calipers and toe the line of what you can get away with if you want to.

Is there a big downside to a shorter 550 mm chain lock vs the regular 900 mm one? I imagine there are fewer options for locking up when there isn't an empty slot at a bike lockup post with the shorter one, but the weight saving is about 2 lbs.

My current experience is with a 19mm internal width rim a 25mm tire from Conti 5k model calipers at 25mm. And that a Kenda road tire 25mm on the same rim calipers to 28mm.

I recently got this 10 year old aluminium trek Alpha 2.3 and it has a carbon seatpost and front fork. I replaced the seat post with an aluminum one cause it had a crank and loose fibres dangling of it. That made me scared of carbon. Now I wonder whether I should swap out the front fork as well. From the outside it still looks fine. No damage as far as I can see. What do ?

Keep the fork. If Carbon just exploded after 10 years without visible outside damage, then nobody would ride it.
>>
>>1800893
leave the fork, but I'd have replaced the seatpost even if it was visually fine. I actually did this on a slightly older trek 1000 with a garbon seatpost and fork, you don't know if the previous owner was paying attention to torque spec or just clamping it down with retard strength like literally everyone does with normal seatposts. Yes, I could have got a torque wrench but one that wasn't going to be shit would have cost me more than I paid for the bike.

Also the actual rating for mine is 5 Nm - it's still printed on the seatpost collar. That's basically finger tight, fuck that. Fuck torque specs in general though, the correct spec is literally just how tight you can get it without snapping the allen key (unless you have garbon).

I want to go touring on my bike but how do you keep it safe during a month long trip? During such trip your bike has all your shit, basically your life's there and if you go solo there's no one to look for it if you go for groceries, a shit or for a beer.
Not to mention it also reduces your mobility greatly.
>>
>>1800897
>rim brake pad wear mark
Not that I'm aware of.
I use shoes w/ replaceable pads (not pads with the molded-in bolt). And I always run the same pads until I think the shoe will touch the rim, or the pads go hard (bikes that I ride less often).
I've had one person tell me to toss them once you get to the bottom of the little cuts, but I kept using them, no problems. The pad was completely flat, no individual nubs, but that didn't seem to make a difference for stopping power or noise.
>>
>>1800947
Get 2 really good locks and you can have some special bolts so people can’t just undue your quick release or thruaxles, also common sense helps. If you don’t feel safe or can’t find a good place to lock your bike up but need to go to a store just bring it in with you, make sure it’s clean fire obviously, Iv never had someone say no while doing this when explaining my situation. Even use locks for your bags with important stuff in it and just try to keep an eye on it.

Bring it into your hotel room too, again biggest thing is make sure the tires are clean before hand. Usually you can hose them off and wipe them down.

Also watch videos of people doing it (Francis Cade has a few videos of him touring America and Taiwan) and read blogs about what worked for people.

fabric makes good saddles.
>>
>>1800941
depends on how much wear the saddle has seen. if it seems to have smooth, shallow indents, and has been kept taught, probably okay. avoid anything with even mild sag or more prominent indents. if you aren't racing, weight is a nonissue. you will have to use a saddle cover and fender to keep water off it.

can't see shit on fork/chainstay pics, brake caliper is probably only rated up to 28mm... With your current tire take a 5mm allen key and try to slide it between the tire and frame at all relevant spots. If there's anywhere that you can't without flexing the wheel then you're probably maxed out already.

All shimano pads of that style look virtually identical except for maybe a part number hidden somewhere no matter if they're the good ones or the shitty ones. If they're over ten years old then just replace them because of age.

https://www.amazon.com/Shimano-Ultegra-6800-Road-Brake/dp/B00GIQBCFW/ref
These are the best ones shimano make and will probably make a huge difference. Bigger up front cost but much better performance and replacement pads are only about $15 for 2 pair and very easy to swap.
>>1800990

6800 version uses the same pads and when I ordered them over the winter they sent the R8000 version anyway. Everyone seems to offer the 6800 version though. *shrug*
>>
>>1801062
true
the turnover on amazon is probably pretty high so you would get fresh pads
The cartridge refills are pretty cheap from lbses also, because they get them loose in bulk at 105/ultegra level, and if you go to the workshop they sell them at cost a lot of the time to you.

imo the cheapest way to get a pad upgrade is used shimano holders from a co-op parts bin or scavanged and loose new inserts from an lbs workshop.

but i'm just rambling and being pedantic your rec was right.

Trued my first wheel today lads. It was mega fucked so any adjustment was an improvement which kept me motivated. I ended up getting it 90% of the way to where it’s maybe +-2mm out from perfect either way. How on earth do you get the last 10%? Is it literally just practice making tiny adjustments or is there a trick?
>>
>>1801069
When they're megafucked it's sometimes impossible, but yeah, it's just practice and care+thought.

Also that last 10% is magic. On a tricky wheel the guy who taught me how to do it stopped being able to explain what he was doing and went into a zone.

You should try to do it systematically one by one but actually you're weighting a lot of things at the same time, left right trueness, up down trueness, spoke tension, and spoke engagement.

Also I think having a proper stand does help a lot and if not then atleast having very good light and focus. Also oiling all the spokes is tedius but it helps

>>1800897
>>1800881
Jumping in on this, I wonder how your posture is? Are you straining to reach the brakes? Your saddle is relatively low and your brakes are about far forward as they could possibly be, and in a funky spot on the bars. But to your question, if that's a good position on the bike for you, then I agree you'd definitely get some benefit by moving to better pads with holders - those one piece pads are never as good and they look old too.

>>1801069
>>1801088
There looks to be a big radial hop in your wheel I'd worry about first - back all the nipples off a bit, focus on addressing on that hop first, then get spokes tensioned evenly and then you can come back to that last little bit of lateral play. Also, if your rim has had some hard knocks in the past, you may not be able to get it perfect.
>>
>>1801088
>that radial true
aaaaaaaaaaaaaa
your wheel might be straight but now it's egg shaped
>>1801079
>Also that last 10% is magic
this, that last 10% is to prepare your anus for the last 1%
also, don't forget dish, truing consists of lateral (x axis), radial (y axis), and dish (z axis), needs to be true in all 3 dimensions
>>
>>1801092
Thanks anon, it’s not my rim, though. I work at a charity that provides a bicycle-oriented space for the disabled and helps them with maintenance, group rides etc, this is a blow-in who came to one of our Saturday breakfasts. I lent him the wheel from our workshop time trials bike so who knows if he would even want his back kek. How would I best approach the hop?
>>
>>1801094
>lateral (x axis), radial (y axis), and dish (z axis)
How is dish on a different axis than lateral? It's the same, it just has to do with where on that axis you're truing to.
>>
>>1801094
That makes sense. So I need to back all the nipples off? Did I waste my time making it straight?
>>
>>1801098
You'll find it easier to get the wheel closer to being radially true if you start with a little less tension across the wheel. And no, you didn't really waste your time. When truing a less-than-perfect rim it's totally normal to need to repeatedly switch between focusing on lateral, radial, and tensional true until you converge on the optimal solution for a particular wheel. Knowing instinctively when it's time to switch focus is just one of those things you can only learn with practice, so no worries, this is how you learn.
>>
>>1801101
Ok cool, thanks, so I’m going to mark the beginning and the end of the egg then back off all the nipples by, say, 1/8th turn each. So the tension comes right off evenly. Then start tightening from the egg, checking for radial true with the sliding plate on my stand. When the egg has come out, I try again to set it laterally. Correct?
>>
>>1800133
A bit late, but I had the exact same issue and solved it with a cut out saddle that I tilted slightly forward. Less reach would help, but you have to be careful since smaller frame bikes also have a lower front end, plus you might actually find that with a proper saddle you don't even need to change your position.

it's complete trash, not up to first world country standards. stick to the larger brands although unfortunately there aren't a ton of alternatives for fixies because of how niche they are. on a tight budget, finding any bike that is close to what you desire might be difficult but stay away from fabricbike. the company is run by a single spanish guy who pretends to have a couple of other employees but it's all him. my fabricbike aero had a badly misaligned frame and numerous other issues. the average person doesn't know how to check frame alignment or thinks it's normal so you don't hear about it much. a proper aluminium/carbon frameset such as cinelli vigorelli is going to cost more. ribble eliminator al was decent but it got discontinued. dolan pre cursa is another budget option. for steel there's fuji feather, ribble urban 725s. on their facebook page there's a guy in the comments complaining about the shitty paint quality the last time i checked so you can imagine that it's not just me who noticed issues but because of how small the brand is you don't hear about the issues a lot. people just silently avoid the brand even though they have good SEO like how americans have mostly moved away from leader and aventon and mostly stay away from other small brands like unknown, throne etc. state bicycle co gets shilled but there has been issues with them. there are some other small brands like engine 11 which i don't know if they're good or not. a lot of this stuff is aimed at normie teenagers who don't know any better and at poorer people in asian countries so you typically don't get the same quality from these smaller brands that are grifting the fixie fashion hype as from the top brands. for instance you can see how many different color options that fabricbike offers, this is abnormal for a bike brand (other than custom colors for an extra fee) and is a warning sign as pointed out by zach gallardo in his advice about beginner fixies to avoid.

I HATE this board so much. Frame size all depends on so many things, how long your limbs are relative your torso, whether you have a sloping top tube, BB height, what kind of handling you want, what kind of riding style you have, road, 90s MTB, modern MTB, fucking sit up and beg wobbly city bike or whatever. or een just personal preference. get off your're high horses and just man up, tell the guy you don't know, and that he should just try the bike and see if it's comfortable.

I honestly doubt any of you have touched a bicycle. you probably weigh 450lbs and have translucent blotchy skin.
>>
>>1801217
for road bikes it's pretty straightforward actually. at around 183cm you might want 58cm on a VINTAGE road frame, otherwise you should be on a 56cm road frame. people up to around 180cm might choose to ride a 54cm frame. 173cm is manlet territory, 52cm would make sense. look at what the pros are riding, nobody at that height is riding 54cm. you can easily compensate for limb length and riding style etc with the saddle height and stem length and headset spacers.

I did the fitting (online with measurements, but I don't really wanna go to a bikefit right now), so I do feel confortable and have no problema reaching the brakes, I'm not stretching so it does feel ok (a bit weird compared to MTBs I'm used to).
I have no idea how old these brakes are, probably as old as the bike itself if I'm not mistaken. Might check it out today on a bikeshop nearby.

On this big incline I talked about before, I don't have the confidence to just roll down, because when I brake, i feel like I need to put a lot of force to stop as much as I would with my mtb (which had rim brakes too, mind you). So I'm just assuming that I'm using too little strength and that the pads are toast.

dude I took my bike out thrice so far and every time I ended up riding 4+ hours (not counting resting). you will end up spending whole day swearing to yourself "why the fuck I wasn't biking all these years" and go on for absurd distances until you figure out a more sustainable route and a more "tiring" gear ratio to get the cardio out of it.

>>1801309
Not the other poster, but I'd buy that.
The tension bolt (at the nose of the saddle) is almost all the way in, that's a good sign. As the leather wears/sags, you have to back that bolt out, so it tightens the leather.

>>1801321
Not all of them have it. Selle Anatomica is the brand I like most, and I used to insist on having a cutout. But I've since had an otherwise identical saddle (they do both kinds), and it doesn't make a difference for me. (The only exception to that is riding in jeans, that thick seam right up the back will sometimes 'flick' against the cutout saddle. Just a small annoyance.)

road bikes are very efficient so you will need to sprint or climb hills to get an aerobic benefit comparable to running. there are a lot of analytic tools out there if you want to monitor your efforts and make it into a workout.

Youll need to work based on your cardio beat mostly. Find out yourmax and do 1 hour workout at 60-70% of you max heartrate.
You can also do interval, start from a stop, Fartlek etc etc. Having hills is a bonus as they are a pure test for your mind resistance and aerobic capacity.

Be sure to have a decent saddle and some sort of padded short. Lycra is best for chafing issue avoidance.

I've remove the non-drive side of my bottom bracket. It says "36 x 24t 70" and if I google this a lot of products show up with Italian style threading.

Would this mean that my drive side bottom bracket is threaded so that I must turn anti-clockwise to loosen it?

Is it possible this shell is not necessarily indicative of what needs to be done to remove the bottom bracket fully?
>>
>>1801416
36 is the cup diameter (36mm)
24 is the thread measure (24 threads per inch)
70 is the BB shell width (70mm)
so yes, it is indeed an italian BB, which means both sides loosen counter-clockwise

You're right, it is easy. It's also easy to look up information on wheel size standards and notations on your magic internet box by yourself rather than having it spoon-fed to you. But I'll lay it out anyway since I'm a nice guy.

We can ignore the tire dimensions since the question specified the same tire size for both scenarios. A 700C rim has an effective diameter of 622mm and a 650B rim has a diameter of 584mm. That's a difference of 38mm. Divide that by 2 for the radius, and that's a drop of 19mm.

Late reply, but I'd back all the nipples off one turn at a time, going around the wheel twice to keep things even-ish. Then look for the high and low spots in the rim, remembering that for radial true you're working with whole groups of spokes, not just the pair of spokes closest to those points. Keep in mind too that what look like low spots may be sections where the rim has been smashed inwards, so feel groups of spokes for tension as you work and that will help you figure out what's going on across the wheel as a whole.

I only have the bare frame with its pain stripped completely. Some said it may be Cannondale but I spend a couple hours looking through catalogues and the rear drop outs + chain stays never match or they don't have a braze-on front derailleur.

Only reason I'm interested is because if it's a tried and tested frame rather than a random Chinese one, I will take the time to source the OG parts and have a project for myself.

i view integrated hangers as a good thing on vintage aluminium bikes because it encourages people to junk them when they have seen enough abuse to bend/break the aluminium hanger. These are cheap things that shouldn't be crashed and it's good to have an encouragement to not ride them past their service life.

unlike your expensive new bike that you really want to avoid scrapping.
>>
>>1801487
... have you ridden it? I really don't see the point in doing a full custom build on a forkless paintless mystery aluminium frame unless you know you like riding it and have sentimental attachment.

Hell half the charm of classic bikes is the paint/patina and the only ones worth repainting are super high end with serious rust issues.

'original' is a nonsense idea for bikes that aren't high end and specific

Don't feel bad. Having little seatpost sticking out is actually structurally stronger. The seatpost acts like a lever the more it sticks out the greater the forces on the seattube and clamp. Plus this flex is inefficient ( although """comfortable"""")

Also if you have an old straight frame don't feel bad either cuz a straight top tube is actually more aero

I am a painter and I like to paint outside. The painting kit is a little cumbersome to carry with a backpack while riding my road bike so I would like to have suggestions for an efficient way to carry my stuff:

-camera tripod, length is 42cm
-painting box around 23cmx23cm and pretty flat, maybe 5cm high

My bike is able to take a rack, but I am not sure if I even should get one. Maybe there is a smarter solution to this.

the painting box should fit on top of any rack no problem, you can either put it inside a milk crate or some other basket and zip-tie it to the rack, or just strap the box directly to the rack with bungee cords, or just old tubes.
as for the tripod... carrying long stuff on a bike is always a bit awkward. one solution is strapping it to your top tube, between your legs. you can also just strap it across a rack and have people deal with your increased width, but then you risk crashing it against stuff

This is probably a dumb question. Got a new set of wheels today, nothing special, quite heavy, thick spokes, but the idea was durability and tyre compliance (the stock ones are a nightmare to work with). What I have is a standard shimano HG type hub body like in MTBs. The 11 speed cassette sits fine on them, but on the stock wheels, there is a shimano 11s road hub, but the spacer they used is thinner then what's recommended. So on the new wheels the gap between the cogs and the frame is really tiny. Please tell me all I need to do is adjust the high screw? I can swap the freehub body easily, but that's another few bucks and I dislike the idea of throwing money at the problem.

V-brakes have more power, a lot more from experience. Easier to adjust too.

Are AliExpress bibs good enough for filthy casual babby?
>>
>>1801758
I beg to differ. Used both a lot and well tuned cantis I find way better. Not sure why that is, but I would guess that by design, cantis pull the brake pads towards the rim always equally, while Vs start on one side and even if you go full ham on the brakes, that one side is always stronger than the other. Cantis have better modulation too.
>>1801778
I'm gonna say, it's not an inferior product and if you like them, that's a patrician choice. Any braking issues with cantis can be fixed easily and the worst case scenario, the pads are shit, but good ones are dirt cheap (look for soft rubber). The secret sauce is to set them at a slight angle, so one end of the pad touches the top of the rim, while the other touches the bottom.

what the fuck are you talking about?

cantis have better brake feel and modulation but vs have better out and out power

This only matters if you're riding steep muddy trails, in which case, you'd be better of with a disc bike. V-s are basically a stopgap for discs for mtbing. Cantis are the better general purpose brake system.

The setup is far more difficult though and relies on a number of factors. Badly setup cantis are terrible.
The best cantis i've ridden and this might be slightly random are the old higher end shimano mtb ones that take smooth post pads, fully taken apart and cleaned, with kool stop eagles. And i have some expensive new cantis too. So i'd suggest you go that route if you can find some, not waste money on TRP.

get a rack
zip tie a big metal basket on it
just very useful generally for groceries etc.
tripod could just be on an angle and strapped down poking out of the rack if the basket is too small for it.

you could also get a length of pvc pipe, like a big culvert one, and attach it vertically on the side of a rack to put tall things in more easily. Cut some small notches around to zip tie it on, or use u-clamps. You could run it flush to the bottom of the top basket and cut a hole in the basket for it.

If it's not rubbing then it's fine. You should carefully adjust both limits. Detach the derailer cable to do it. Move the derailer against the limits with your hand, while pedalling in a stand/ with the bike hanging.

Broken how? Just has a lot of slop in it?
If you're running STI shifters and you have a boss for it, the easiest solution is to switch the front shifting to a friction downtube shifter. That will be much easier to setup and more forgiving for everything. Plus it's period-race spec. Look at Lance with that setup. That would be my preferred option.

Old indexed road triple stuff is generally shit.

Shimano FD-R2030 Claris Triple Front Derailleur is the new part i'd buy if you really want to fix it or don't have a dt shifter boss (you might still clamp one on). Really the best replacement though is something old/good without slop, for 7/8 speed, that has the triple middle ring pickup groove and is a road part.
>>
>>1801803
You are in a triathalon so depending on the terrain this may be a dumb question buuuuut.....why would you need the middle and small ring on an ancient 3x7 rig?

Alternatives are to call around and see if a bike shop or better a bike coop has the part. bike coop are run by stinky communists so if they fix it you'll have to pay them the eqivalent amount an LBS would charge and they'll take the money and give bikes to hobos.

Also keep in mind he said the deraileur was worn, not broken.

Also worst case scenario if you have a extensive hill portion is to dismount, shift to desired ring to climb and fuck that chicken

triple on an old race bike doesn't even mean wide gearing. Your standard race bike now has far wider than a tight road triple with close cassette from that era. Dura Ace cassettes are like 11-30. Small ring on a semi-compact isn't much bigger than a granny.
>>
>>1801803
You might also consider, if you want to spend some money, converting to an r-2000 claris crank with matching fd.

As a stiff race bike it will be appreciably stiffer, and depending on what you have the triple may even be desirable for touringfags so you can recoup some cost. You'd still need to re-think the shifter but again could just be a downtube shifter.

Just from testing he believes it's worn. I don't know much else from it. I don't have bike with me right now either as I had to leave overnight, but he was going to put a new chain on it and look at the tension on the cables and see if he can adjust it so I can transition from the medium and large ring without issues. Would be much preferable instead of gambling if it's going to catch every time I shift.

There are 2 hills on the course that you have to do twice. One of them isn't too bad, but the other sucks if you're not on the 1st gear. I can do it in 2nd if need be, but I'd much prefer 1st if I can.

I understand this. My point is that most triathalons for cities will have a pretty tame cycling portion and even on an ancient 3x7 I wonder why he'd have to leave big ring but he answered it here>>1801865 I guess it's a circuit with a couple poopy hills

I got it loosened with a lockring wrench I had lying around. Then the actual top race was stuck, so I ended up using an old pair of pliers to grip the patterned surface. thanks frens.

I'm 180cm and I ride a 54cm, and it feels a bit small with the hands, but I am fat and not used to drops. I have the saddle relatively low so I think I couldn't handle a 56 either though. Bike fit is so finicky.

Just buy a new bike bro.

>is paying $11 direct from china for something that normally costs $100 good enough?
>implying bibs aren't all made in china
It's probably the same manufacturer, selling directly to the costumer. I'd bet my ass they sell each one for 5 or less to western manufacturers.

>>1801934
they're not the same they just print whatever design on some cheapo bibs/jerseys. they can do custom designs too.
>>
>>1801934
>probably
>bet
oh so you don't know, thanks
>>
>>1801937
not him and i cant prove it in court but i know from myself and a lot of other people that legit bibs are legit and aliexpress bibs are shit

if you're just gonna sit in your pc chair and jerk off in them maybe it doesnt matter so much

How much slower is an XC bike on gnarly trails, whatever the fuck that means. I am basically new to MTB and have not been on an MTB since rigid 26ers were a thing and nothing is the same anymore.

Am I right that XC bikes are designed to be ridden on flattish terrain, and "progressive" trail/enduro geometry is basically designed for climbing (steep seat tube) and descending (high trail) only? Because 76 seat tubes with zero offset posts seems like a fucked up position for riding on flattish terrain, and they seem to have very shallow head tube angles, more than I would need going 20mph.

I expect the bike to be able to handle all offroad shit, not just skilifts and be reasonably comfortable on fire roads and streets.

your whole question and any answer you might get to it is retarded
it's all so ridiculously skewed to whatever your biased nonsense is that you look from that direction its totally meaningless

people ask this kind of question and don't even mtb they just ride smooth paths you could ride on a road bike. Not saying thats you but every genre of bike moves in a direction from each other that you might move also in a direction the same amount or more

>it was made on the same continent as good products so it's probably just as good

>>1801783
honestly after using some from aliexpress, you better off investing on better stuff like in decathlon, better quality there.
but if youre using aliexpress stuff its ok for under 1h use, and they can print custom design on it, got me some long riders fortuna kit :^)

The Ultegra 6800 is free for me because someone gave me a bike they crashed. The frame is fucked, but the drivetrain is fine.
>>
>>1801963
You need drop bars and brifters for it also new double chainrings and new fitting cassette etc…
Basically you need to make your fx into a roadbike with that heavy ass frame. Not feasible.
Get a road bike that fits the ultegra instead

get a chinese carbon frameset

>>1801843
Thank you, that was what I was looking for and I just wanted to make sure if there isn't any bag I overlooked. The basket seems to be the most reasonable and versatile option, there are even many out there that can fit the tripod, so I don't even need to modify anything.
