whose taken a spill on ice so far this year? is the bike ok?
>>
>>1885091
i believe that most parts on a non shitty bike should be fairly durable and survive simply falling off your bike most of the time. for example mountain bikers get into full on crashes like not landing their jumps or hitting a tree without needing to replace their frame very often. some shitty bikes might have a frame that wasn't welded straight in the first place and not heat treated properly or whatever. but you shouldn't have to worry too much about bending the frame just from riding it or even taking a spill.
>>
>>1885095
nah crash damage is random and everything is prone to take it

mtbers fuck their shit up all the time
>>
>>1885091
Nothing so far this year.
Took a spill on an icy turn before the snow fell this winter, because I was lazy and thought I could put off switching to studs until the weekend. Scratched up a brifter and a knee, and my wrist was sore for a couple of months after that.
>>
>>1885091
Took a spill in November '21.

I was cocky, didn't see the black ice, the ground was completely frozen at night. Textbook drop, nothing damaged on the bike except some bar tape got scuffed. Worst was that my expensive rainjacket got holes in it and my house keys pierced my cycling pants.

Got ice tires

They're focused on the OEM market and trying to gain acceptance for their parts as complete groupsets. It would be a step backwards for them if they moved away from the standard they helped create.

As an anecdote, I've had reason to talk to folks in the FSA office in the US a few times over the years and they by far give the least fucks of anyone in the bike industry or are the most stoned. You get the impression they simply do not care about consumer sales or folks in bike shops.

Hi, I'm looking for a replacement BB to match this FSA crankset, we got one with bad bearings

I did, they say it's your proprietary part, I have the part number right here

what to wear in order to keep ears warm from windchill, while already wearing a helmet?
>>
>>1885299
Buff windproof, there’s a lot of the material and it’s thin and stretchy so you can fashion any kind of folded headgarment you want to cover your head
Also folds up into basically nothing, my favorite cold weather piece
>>
>>1885301
that would definitely work, assuming it's quite breathable?
>>
>>1885302
Well it doesn't cover the part of your ear that gets the coldest without constantly riding up yor face, so there's that.
>>
>>1885304
It’s definitely useable the way in the picture but fully covering your ears without riding above your nose or chin depending on where it is, but personally I like to pull it way over my head, fold it over below my nose, and fold it back up again to cover the top of my head, this covers my ears and makes a little mouthcover you can move up and down without affecting the rest of it (backlava in this picture); like I said it’s really stretchy and there’s a lot of material, the lower 6-8 of my specific one is fully windproof shell-like material for the neck
>>1885302
It’s actually breathable and dry for a pretty long time covering my mouth with one or even 2 layers of it, but after a while it eventually gets kinda moist in the mouth area unless you pull it up and down often enough, the moisture really doesn’t spread anywhere else and it’s WAY more breathable than other face masks I’ve used
>>
>>1885299
I wear a headband that covers my ears or if it's colder I wear a skull cap that extends down enough to cover my ears as well.
>>
>>1885301
Also that guy definitely has more than one layer on his face, it’s really thin and almost see-through when stretched, beard stubble will easily poke out of one layer

What do people mean, or rather, how do you feel the bike or the wheels "twisting" under you?
I'm not a light rider by any means (180cm, 80kgs), neither am I an athlete, however, I don't feel like me wheels "bend" when I ride off the saddle. Is this something you have to test a higher end bike in order to feel?
>>
>>1885388
it's most noticeable with box section rims. especially if you have 30+ mm deep rims (common on disc brake bikes) it's not really a concern. with stiff carbon rims, the spokes might flex (especially with lightweight bladed spokes) while the rim stays rigid, so that you notice it in the form of brake rub if you have rim brakes.

also a question, im doing 600km a month, for the past 18 months or so, thats at minimal 10k km done, i havent changed my chain, only lubed it like every 2-3 weeks, is it normal for a chain to withstand so long ?
>>
>>1885428
Overusing a chain doesnt brake it.
It get overthly long and then it starts damaging your gears.
Probably you need to change now the chain and also the cassette, otherwise you will quickly ruin the next chain.

Buy one of those cheap chain calipers you find at any bike store to chek how bad it is.

It's not a rational question it boils down to whether the bike speaks to you or not specifically if you like the color. Also 'good condition' is incredibly meaningless.
And if you want the drive depends a lot on how much you like going on random ass drives and might make a day of it.

I have a State 4130 road bike I got a year ago. I learned how to ride it and then I got bored and it’s been collecting dust mounted in my apartment.

I want to sell it but I’m not sure how much to list it on Craigslist for. All the parts are original but it has tissues sith the chain. The chain comes off when I change gear too far from the “neutral” position. That is to say that the further I move the lever to change gear the more the chain becomes misaligned and pops out when I ride it. The chain also get la caught on itself sometimes and it’s movement staggers when the gear is shifted. I don’t know the terminology since I’m a bike noob.

I’ve only ridden it with 4-5 miles around my parking lot as I was learning. It’s not rusty or scratched. The only other listing for my area is like 500 usd for the same bike. It retails for 600 but I would be fine getting 200-300 for it. Again, I’m a cycling noob so idk what to realistically list it for or what people normally pay. I’m gonna look at it again this weekend and take some photos for the listing.

If I should ask the bike general just lmk somebody. Ty
>>
>>1885456
200 is about right. Usually an (actually) good condition used bike should price at half a new equivalent. Being practically unused counts as 'good condition' but then it has shifting problems so it's not.
It's not the kind of bike that is very desirable to people who know much about bikes so it's probably not going to be an 'easy fix' for anyone who is interested in it, although there would be several easy approaches to fixing /improving the shifting for someone who does know what they're doing.

Take good photos and don't be too wordy. Just say the shifting kinda sucks. You can still just not use the gears much right? It's got use even unimproved.
>>
>>1885456
Also man, did you actually stop riding it because of the shifting issues? Or the fit not suiting you? Why don't you want a bike? Those ones are not bad. You could fix whatever you don't like about it pretty easily.

A narrow-wide chainring would stop the chain dropping and the shifting can probably be improved just by adjusting it which would cost you $20 or so at a shop. The deckas etc narrow wides on aliexpress work fine.
>>
>>1885461
I didn’t like the fit. It was really heavy and I hated carrying it down/up my steps. I mostly got it to try it out and learn how to ride but once I got the hang of it I had no more desire to ride it or go anywhere. The beach is far and I don’t have a car. My work is too far to ride a bike and anywhere else I go is close enough to walk or use my skateboard. I could also use the cash.

There’s a bike shop a little less than a mile down the street but I don’t care enough about the bike to go down there and have it adjusted.
>>
>>1885462
>I didn’t like the fit.
Extremely common story of why people dislike cycling. Spending the time and money to adjust the fit is absolutely critical with a bicycle.
You bought a bicycle which is extremely easy to adjust the fit on too, as you don't have to re-cable the shifters to do so, and it has a threadless steerer.

It would be easy to raise the bars significantly or run a different type of bar.

How far away is the beach, or your work? Seriously? Why not put a rack and or basket on it so it's useful for shopping? If you don't have a car I really don't understand why you don't want a bike.
>>
>>1885463
My work is like 8 miles. The beach is like 5-6 miles but if I ever went there it would be just to ride on something that’s not the sidewalk. For shopping I go across the street to the supermarket or my mom goes to Costco.
>>
>>1885468
>>1885463
I should also mention that I really want to free up the wall space it’s taking up since my room is already small and I want to install some new shelves for my miniatures. I can see myself cycling in the future again but the one I got now is just too big for my space and purposes. I’m hindsight I should have bought a smaller used bike that doesn’t take most of my energy to take down off the wall and carry down my narrow staircase.

Attaching your phone to your bike is for retards so
>>
>>1885386
what this probably means is that your chain and cassette wore down together so they fit each other. so your worn cassette doesn't fit your new chain and needs to be replaced. if I'm understanding you properly. cassettes generally last 3 chains worth, or so they say .

videos for everything are in op links.
>>
>>1885410
I say the price is fair but I'd only make the drive if you live in the middle of nowhere and there just aren't going to be any other used bikes for sale nearer to you. i.e. if you live in a city then hard no and keep looking.
I got a seller to come to me once because he lived in the middle of nowhere and he liked to go to the Target near me. but he didn't live 75 miles away or anything.
>>
>>1885391
I own a 2000's aluminium bike with aluminium wheels, so maybe that's why I'm not feeling it? Doesn't really make sense in my head, considering all the carbon stuff is marketed as "stiff as it gets".
>>
>>1885462
>I don’t care enough about the bike to go down there and have it adjusted
it'd cost like$30 or so and it's a helluva lot easier to sell a bike that works properly and then you can charge maybe $50 to $100more for the bike i.e. you're paying yourself $20 to 70 to make the trip

cycling cap with earflaps

>>1885388
>>1885505
Unless a bike is really terribly flexible or extremely stiff or you're a very strong rider on something inbetween, that flex is something that you won't recognize until you've ridden enough different bikes and wheels to learn to feel the differences between them - but it's a big part of why different bikes will 'feel' fast or slow. I learned to pick up on it by riding old bikes with friction shifters, because with those you really notice when frame flex effects the tension on your shift cables.

Only if you're always replacing the chain as soon as it hits 0.5%.

>>1885391
Every rim except antiques and the very cheapest walmart shit is "box section".

>>1885428
It didn't last 10,000 km (unless you're keeping it super clean and using high end lube), it's just that everything else is also worn to shit too now so it hasn't started slipping - yet. Assuming you don't have a proper chain checker, use a ruler to measure across a dozen links as accurately as you can while the chain's under tension (use the edge of a pin or plate as the reference point). Theoretically it should be 6 inches exactly, if it's 0.75mm or more past that it's fucked.

Do you really need to service your suspension every 100 hours? Or is it just a scam from suspension companies for you to spend more money?
>>
>>1885565
In my opinion you can start feeling suspension performance degradation earlier than the recommended time intervals (I actually do “50-hour” bath oil changes and cleanings in my serious mountain bikes but never a “200-hour” damper disassembly and seal replacement), suspension will “stay alive” much longer than maintenance records suggest which I think is more what you’re looking for
>>
>>1885556
Chain slipping is the chain falling off the gear so there's suddenly zero resistance for a moment until it catches back on. At minimum an annoyance, at worst a big safety risk. Not really anything a bottom bracket could do similar to that short of magically disappearing along with the axle so the pedals were attached to nothing.

>>Fork starts violently shaking when braking
fork shudder is a common issue with bicycles of all kinds, including threadless ones, disc ones, and suspension ones.

Bicycles vibrate in all kinds of funny ways and a combination of several quite random things can cause it.

It's also not unusual to have to service any type of headset semi regularly especially if it's being sprayed with water. You may want to fit a small fender to protect it if that's the case. You can DIY one out of a coke bottle. The headset that a shop would put on that is also likely garbage and has zero sealing. You can tell if it's loose. Hold the stem in one hand and a fork blade in the other and try to shake it and feel play. It could be something else.

Your brake being loose or badly adjusted, or your front hub having play might also cause it. Sometimes toeing brake pads can fix it, although you can't toe those.

You should fix this issue but you should also aquire a better bike. That bicycle in your pic is truely garbage. It has fucking steel rims and stamped steel brakes. It's never going to be good and putting much time or money into it is truely retarded. If you want recs on a better used bike, a worthy project, post your local craigslist and height.
>>
>>1885615
>Is it normal for chainring to look kinda worn after 1500km
Find a picture online of a new one of the same model, teeth are often made in strange shapes and not all the same because it helps shifting. Chainrings dying after 1500km would be terrible even for walmart shit.

>How do you camp in a city

It's harder with a bicycle and a tent rather than a bivvy or a no fucks given attitude towards insects. Not impossible though, by any means.
I've camped in cities a few times. Most cities do have big parks that you can stealthily hide in. Basically you scope the spot in the daytime, set up after dark, and leave early.

real talk though, don't stay in cities. Ride out of them or avoid them altogether.
>>
>>1885810
>Hold the stem in one hand and a fork blade in the other and try to shake it and feel play.
That's exactly where the play is. Stem is solid but the fork is what moves forward and back. The wheelbase of my bike changes by at least an inch due to it.

>>

Man, unless you’re getting a killer deal (which admittedly are actually popping up a lot lately), you’re gonna be sold some tourney bottom-tier trash for $500 when you could’ve gotten something way better for $600 and a little research. I remember walking into some shops looking for a cheap bike for a girl (don’t do this, it’s a meme for a reason) and was shocked to see everything in the shop was $200 more than I was expecting. You didn’t even get hydraulic brakes until $1000+

Take it apart, check that the headset cups and races aren't moving.
People that ride their bikes incorrectly usually break their shit. I doubt the problems you're having don't have to do with how you ride.

so I have a marin muirwoods rc which comes with a nexus 8 hub (Shimano Nexus 8-Speed Internally Geared Hub, Centerlock Disc, 32H, and a MicroSHIFT 8-Speed Thumb Shifter), I love the bike but this fucking hub is unreliable and tends to skip at the worst moments

my question is simple, what is the smartest choice,

1) replace with an alfine 8 (easiest)
2) replace with a rohloff (most expensive)
3) try to retrofit a derailleur (think 7 speeds is the widest I can go there, will require new spokes and other parts)
4) turn to single speed (will require new spokes and other parts)
5) sell and buy bike without fucking nexus 8

I love the bike, but biking in paris I need to trust the drive train when facing these cunt frog fucks

How much difference will one missing link from a bike chain make? When I say one link it's one inner and one outer, I lost the pin when I removed the chain, it's a very rare and hard to get hold of chain that's in excellent condition, I wanted to re-use it after I overhauled the bike.
>>
>>1885993
Whether it matters depends on whether your chain was properly sized before or not. If it was the right length before you can ride with the chain 1 inch shorter, you just need to be extra careful not to shift into a large-large gear combination.
>>
>>1885993
Depends on how much slack you had in the chain in the first place. It'll probably be fine if you don't shift into big-big.

>it's a very rare and hard to get hold of chain that's in excellent condition
What? No it's not. Every bike shop sells new chains. What the fuck kind of rare drivetrain are you running that you can't find a chain for it online? Chains are consumables and should be replaced regularly.
>>
>>1885996
I'm thinking it was correctly sized, just going by the quality of the frame and parts, and the fact that it was assembled by the frame builder.

I'll give it a go, I tend to stay on the middle ring except on steep climbs when I may drop to the granny ring.
>>
>>1885997
No mate, it's a Rohloff s-l-t 99 8 speed, in near mint condition, you can't find them anywhere, and when you do they fly for more than a hundred quid.
>>
>>1885999
That’s if they sell, but they never sell because it’s a consumable item that offers no performance advantages and is basically identical to a sram 9 speed chain for $10

If you really think it’s worth more than $10, then you try to sell it, and replace it with a normal $10 chain
>>
>>1885999
>it’s a fucking 8 speed chain
Ahahaha
>>
>>1886004
I want to use the Rohloff because it's a great chain renowned for its durability, plus it came with the bike, so the drive train, although not greatly worn, was paired with this chain and therefore it should work well.

It's widely considered to be the best bike chain ever made, one of the reasons they stopped making them was the lack of repeat business, they didn't wear out. You don't just switch it out for a £10 throw away consooomable model.

Ok so that's fucked. Your headset is WAY too loose and likely something is wrong in the way it's assembled. Take it apart, look at some RJ videos, and put it back together with fresh grease.

>What are some good brands/models to look at in the roughly $150-350 range \
It doesn't work like that. Practically every brand made good bikes and for vintage the best are often quite esoteric. I hadn't even heard of most of my bikes when I saw them for sale. It doesn't help to look for anything specific, but more, to understand the marks of a quality bike, and one that is in good condition. Which is a complicated thing. That sekai is an excellent high spec bike, and very beautiful. But it is older than I would normally recommend to people, and that makes it more difficult to work on, source parts for, and with less utility.

It's easier to explain what makes an old road bike bad.
>stem shifters
>claw derailer hanger
>suicide brake levers
>riveted chainrings
>steel rims
>steel seatpost with seperate clamp

Those are all the major tells

nice bike:
>specifies cromo or a specific tubeset, raleigh 531, tange, columbus etc
>downtube shifters
>high groupset hierachy, easy to look up, lots of club bikes with exage etc are quite good but if you see a bike with 105 or 600 parts you know it's good. That Sekai for example has a frankenstein drivetrain but a 600 arabesque derailer, which is next to top of the line. It's not a particuraly good part itself (personally, i hate how it looks, and a cheap more modern derailer will preform better), but it signifies that it's a higher tier bike.

On the sekai also, see how the seatpost clamp is like part of the post? That's a major tell.

Try re-cabling it.

Iunno how easy retrofitting a derailer would be but that would be my next option. I've ridden a new (and old) muirwoods, the derailer one, and thought it was excellent, so the frame probably is worth perservering with if you cbf and don't have much money to replace/ugprade it.
You wouldn't get new spokes, you'd just buy a different rear wheel.

Speaking of discontinued stock, how long until we are all forced to run minimum 9-speed deraillers?
I recently had to order replacement STI shifters for my 8-speed touring bike and had a pretty hard time finding a set that would get here in less than a month. Out of curiosity I went looking for replacement chainrings and they were similarly scarce.
I mean to upgrade the system to 9-speed at some point anyways but still a bit unnerving to know I may not have a choice at some point when a part fails.

Derailers? doesn't even matter. 7/8/9 is all compatible. Broadly the same with chainrings. 8/9/10 too.
I run a 9 speed ultegra derailer on my 7 speed road bike, with the 12-32 sram cassette and 7 speed 105 dts. Works perfectly.
Lots of good old parts out there too.
>>1886116
and I sort of agree with this.

I don't think forced redundancy of drivetrains is really a problem. The UN55 disappearing is by far the worst blow of retrodouchery. Everything else is kinda all good.

Sound needlessly expensive. But sure, you can do that if you like. If you don't care about cassette life then any chain should last you 2 years.
>>
>>1886160
You shouldn't need a new cassette every time, but if you're not worried about the cost then go for it, but letting the chain get worn out eventually wears out the front gears too, which are more expensive.

>>Chain goes WROOM like in video

there are some butthurt anons that hate on chinese stuff but those cranks should work fine. in terms of the bottom bracket, people say that the cheaper bottom brackets tend to have worse seals to protect against water and dirt, but imo you don't need a $100+ meme bottom bracket, you can get a cheap one and replace it when it starts to go bad. just install it correctly with the right torque and bearing preload.

If your saddle is staining your pants then I'd expect that someone did something like applying shoe polish to it at some point. Only way I can think you'd solve that is continued buffing with a soft cloth until the all of whatever is on the surface of that saddle now is gone.

The previous chain worked flawlessly and was in very good shape, I changed because I needed a chain to a different bicycle. The cassette seems to be in good condition too.

I think the problem is the new chain being too, I've already removed a couple links but when on the lowest cog and smallest chainring the rear derailleur has no tension and completely folds.
>>
I had an issue with a new chain skipping on a new cassette. Turns out the indexing was out of alignment. What would happen was the edge of of the chain would ride up on to the teeth instead of the links engaging with the teeth and then it would skip. Re-indexing the shifting solved that problem.

Beware that KMC from ebay or amazon or aliexpress etc is probably going to be fake and the equivalent of a cheap chain.

Prefer those two because quick links. There used to be different specs of X8 so if you're looking at older stock in a bike store you might find X8-93. There's also a gold one.

>>1886374
some people go through shimano/sram outboard bearing bottom brackets in a month, not sure if the quality is really that bad or if it's caused by improper installation, maybe the frame is fucked or they're not torquing it correctly. a $100+ bottom bracket will probably last for several years but it's meme tier on a budget build.
>>
>>1886386
Shimano outboard bearings are reasonably cheap and the quality is better than aliexpress. It's the middleground sensible option. If you are actually tearing through them, then there's a different problem.

With a poorly engineered bb shell, it may actually make sense to get an expensive sleeved bottom bracket which can to an extent compensate for/ correct the poor frame and extend bearing life not because the bearings are better but because it aligns them better. Plus then the bearings themselves can be individually replaced. It's more like you're upgrading the frame than buying meme bearings. You could even then go back to chinkshit bearings, although, why.

I'm in favour of chinkshit generally but not bearings when a somewhat but not ridiculously more expensive better option exists, and that's my opinion from using both in a variety of applications and generally noting legit mid stuff to be quite a lot better.

>>1886227

It's a fucked up frankenbike with a nice frame and some nice parts. Probably rides fine as is, and could be improved a lot with some tinkering and a few different parts.

$700 bike is solid but probably has some 'budget' components on it still. $2k bike is for people who are pretty serious and want fancier shit. IMO the second-cheapest model is the ideal one to get if you're a noob, or for a mountain bike (that you intend to actually use as a mountain bike) the cheapest one with a single front chainring and hydraulic brakes.
>>
>>1886445
most $700 bikes aren't proper gravel bikes with drop handlebars
carbon fork
lighter and more compliant frame, lighter build overall
outboard bearing cranks
tubeless/nicer tires (tubeless ready rims at least)
sturdier wheels, more reliable/serviceable hubs
hydraulic disc brakes
better gear ratios, smoother shifting
generally everything is designed and put together by competent people, the geometry, all the minor components and aesthetics are nicer overall

I have an old Shimano 105 groupset (RD-1056 I believe it says on the derailleur) and the cassette in particular is pretty beat up.

I have a front derailleur problem. It'll only switch from the small ring onto the big ring when I'm in the smallest cassette cog. it's been doing this for the past few days where before I could go from small ring to big ring and vice versa while on any cog of my cassette

I think I found the problem, since I wasn't using a quick link, when I assembled the chain I pinched one of the links and it was too tight and didn't follow the teeth and just kept getting stuck up in the air. Now seems fine but it's yet to be tested outside.

>>1886394
>>1886393
oh man, you're gonna trip when you ride this after only ever having ridden that piece of crap. cop it like it's pot
>>
>>1886514
well, that would explain it. the quick link is only for taking it on and off, new chains have to be sized by removing the extra links and that requires a chain tool. when you size it and re-join it, you press the rivet back through the link but this unavoidably overtightens the link, as you found out. you have to flip the tool to the opposite side of the rivet and push it a little bit back towards you (it helps to push it a TINY bit past flush on the first pass so it ends up in the right spot when you push it back). then you check it and see if it pivots freely as easy as the rest of the chain. if not you have to fiddle with it back and forth to get it totally loose.
>>
>>1886519
a lot of tools have a second position to lay the chain in to help loosen the rivet

>>1886513
look at the front derailleur from above, is it in line with the chainrings? sometimes it can get banged out of alignment if the clamp is not tight enough
if not, then maybe you just need to tighten the shift cable a quarter of a barrel turn

>>
Going to build a bike and feel like experimenting with a few new things:

1. I might want to play with trail. To do so I could get a 2nd fork. Does anyone have experience with a 1" ahead stem? I figure it might look the part and I wont have to try and find a for with the right amount of threaded section.

2. I want the thing to be a 1x drivetrain and I never had a 1x (except single speeds and hubs if that counts) and I want to know if I can slap any wide range 11-50ish casette that fits the hub and the rear deraileur has capacity for, protect the chainstay and maybe add a chain guide or do I need weird chainrings to stop it from dropping, clutched derailleurs and what not ?

3. Should I aim for a neutral chainline in a gear I expect using the most or is there a better rationale ?

4. Is there a place that still makes or sells NOS of the old school aero bars ? I got eyes on one but the seller seems to think he knows what hes got.

I want it to be ridiculous and outrageous. Not necessarily practical I have practical bikes. And 'normal' pursuit bikes and stuff.

Slipstreamed a car on the aero bars. Another car upfront slowed down for a turn.
So did mine. Was on the brakes with all the weight still upfront. Locked up on icy puddle. Went of upon regaining traction. Had the hoodie up so I guess that took most of the smash, only somewhat numb. But devastated when I saw where the handlebar hit the toptube.
Regarding the severity of the damage: I think this is mostly cosmetical. Of course its not the same as before. But then again I've ridden worse composite fuckery.

They're great, it's no different to 1 1/8", numerous nice headsets for it (cane creek 40, etc), and you can easily shim 1 1/8" stems until you find the correct meme vintage stem. Actually finding the 1" threadless fork is the hard part, much harder than the correct threaded one.

>I want to know if I can slap any wide range 11-50ish casette that fits the hub and the rear deraileur has capacity for
yes
>do I want a narrow wide chainring
yes you do, 1x works ok without it, but with the big gear jumps and a bike that will be ridden hard you'll drop chains and it will be annoying/dangerous.
>clutch
not necessary unless you're bashing it around a lot in the highest gears. It's mostly to prevent chainslap
>should I aim for a neutral chainline in a gear I expect using the most or is there a better rationale ?
Yeah? Or middle of the cassette. But really you're gonna have to be flexible.
>Is there a place that still makes or sells NOS of the old school aero bars ?
Cinelli Spinaci got re-issued recently. They're floating around, often quite cheap. I also commonly see simple silver Nitto aerobars on the used market. And old trifag stuff is worthless you often see free aerobars, black though.
>>
>>1886598
sounds like you're gonna be running a flat bar too. Just do inner bar-ends instead of actual aerobars. Can get a similiar position and it's less obnoxious looking.

What's the model number of the cassette? I think that was roughly the time they were transitioning from uniglide to hyperglide so it's possible a new cassette wouldn't fit the hub.

What? No. Uniglide is -some- 80s shit. Anons group is from way after that.

>>1886625
You wouldn't believe how well everything else held up, structurally. Even the aero bars which took everything. Ive checked and handlebars and top tube must have flexed ungodly amounts to have ended up where they did. Damage being limited to what is essentially clear coat and maybe some layer seperation actually impressed me quite positively.

i live the draft life too but man drafting on aerobars is real dumb lol and now you know why

Is there a practical limit to friction shifting the casettes with more cogs ? I do 10 on a daily basis but wonder if the new stuff, like 12 or so, gives you too tight of a margin at some point ?
>>
>>1886648
never tried above 10 but i've heard different takes on it, probably depends on a bunch of factors. Bodgy shit is trial and error anyway to see if it works or you like it, there's no definitive way to look at it.
>>
>>1886650
will the jockey wheels need chamging to cooperate with the narrow chain ? Or is it worth a try to get a 12 spd casette provided I have derailleurs with equal or greater total capacity ?
>>
>>1886659
probably not. you'll get better friction shifting without float though.

>is it worth doing this stupid frankenbike meme
not sure how to answer that
>>
>>1886519
It's exactly that. Now get this I didn't have a chain breaker and was using a vise, a nut and a pin to remove the links. Got so frustrated that left the house to go by the proper tool, then managed to remove way too many links and on top of that pushed the rivets all way through till they fell off, it was a pain in the balls to get them back on to be able to tighten them again.
It took me the best of 3 good hours to fix the fucking chain lmao.

Now I have the back wheel to true and I don't have a truing stand, have a diy tool and never done it before so hopefully parktool tutorial will be up to the task.
>>
>>1886665
lmao. anon please don't ride this bike in a way that you would crash if the chain snapped. Like, don't stand up/ forward and sprint on it.

Also truing wheels with zip ties isn't that difficult, just do remove the tire first, makes it a lot easier, and if the nipples are hard to turn, take the time to oil them, or you'll strip them out and get wind up.
>>
>>1886666
I use a magnet and a paperclip. Many ways to skin a cat. I never got why some people want a 'trueing stand'. I build wheels from ground up in a larhe chuck sitting on the table but im sure its just as easy to do in a frame.
>>
>>1886676
use a good wheelstand and you will understand. It's nicer and easier. The sound cues you get from the indicators on the park ones makes it a lot easier too.
>>
>>1886665
so you went through all that bullshit with the chain and then when you came here for help you figured it was because of the front derailleur? fuck outta here
>>
>>1886666
>lmao. anon please don't ride this bike in a way that you would crash if the chain snapped.
I'm unironically riding it on a week long trip but desu I think it's safe. The links are looking good now.

>>1886679
No, I figured out the problem was a pinched link that didn't followed the natural curve of the teeth.

After seeing how gravel bikes are just 90’s mtb bikes rebranded, and modern mtb’s ride completely different, I’m leaning towards a gravel bike.
I’ve narrowed down my wants to a steel frame with 2x, I like Kona and Marin’s offerings but I have no clue what groupsets are good/bad. I can find their gear count and specs but not if they’re made of cheese or clunky. Is Shimano Sora any good?
>picrel are specs of Kona Rove $1600
Alternatively Marin sells a steel Nicasio for $900 and I can upgrade the groupset.

>>1886800
replace valvestem.
There is flats on the threads that accept the cap. Get a wrench or pliers on there and remove the stem.
Install a new stem in reverse fashion.
You're good to go.XY8VMM

>>1886800
In the future, only unscrew the valve halfway. If you use a portable bike pump, use one hand to hold the valve stem straight. They intentionally make this shit break easily so numales get frustrated and buy more.

How to repair a ripped saddle?

Can I glue the flap back down on to the foam? What type of glue would be best for that?

Anyone every try installing Campy EPS on a CAAD12? How did it go? I see that the only hole on the frame where the EPS connectors fit through is the hole in the seat tube.

Pic unrelated, just a really nice CAAD 12
>>
>>1886837
Some kind of rubbery glue, like shoe goo, would probably be best .Squirt it under the edges of the rip as well as on the rip itself to seal the whole area.

Then line it with electrical tape.

If it were me I'd probably just wrap tape around it I'm a bum.
>>
>>1886598
i can highly recommend this CNC narrow-wide chainring, it's really cheap on aliexpress (look through different listings to find the cheapest). it's 130mm BCD but there are other ones as well. stamped/coined chainrings can in theory be more wear-resistant than CNC chainrings but most high end chainrings are just CNC machined, it makes them very round and you get more elaborate 3d structures that improve the stiffness to weight ratio.
>>
>>1886605
maybe tap it with a coin and check if it sounds dull around that spot. the coin test isn't perfect but if it works then the frame is obviously busted. carbon is still possible to repair though.

I just used shoe goo to stick a piece of inner tube rubber over a large hole in my boot (for those who remember, the tire patches eventually fell off) and it's solid af.

I'd try glueing that flap down to the foam with it although presumably it'll harden up the foam I'm pretty sure it'll hold it no problem

ah yes i forgot to mention that those come in 46-58t. but, even without handling it in person, maybe you can imagine how stiff a 46-50t chainring is with this truss-style construction >>1886182, when even a 58t may be adequately stiff for most people. the stock chainring that comes with sram s300 can very easily be bent just with your hands. the litepro takes hard effort just to bend it a fraction of a millimeter to get it to lay perfectly flat against a glass mirror, yet it's only 8.5 grams heavier than the sram chainring.

I really don't understand who, aside from smol wheel folders, and e-bike fags would actually want a 1x chainring that big.

narrow-wide works totally fine with a narrow chain, it doesn't interfere with the fit of the chain against the teeth. even with a wide chain it might work as a weight optimization while keeping excellent chainring stiffness but it might fit better if the wide parts of the chainring go in the narrow parts of the wide chain.
>>
>>1886927
and here i thought big rippers were a negro thing
>>
the litepro chainring is really affordable as well. with 130mm BCD and 3/32" width, 48-50t your options are a bit limited. for example pic related doesn't even look like it's better than the stock sram s300 chainring.

actually i don't think it's the same chainring but it has a very similar idea with the truss style design
>>
>>1886940
Fixed gear bikes are supposed to be the most simple and pure versions of themselves.

Narrow wide is gratuitously overengineered. There's absolutely no reason to have it. It's at best 'not bad' and in my opinion will worsen drivetrain feel and increase cog/chain wear.
Aesthetically, theoretically, for the ethos, and imo, for practical reasons, it is wrong.

>weight optimization
>removing material from the chainring teeth is a 'weight optimization'
you have to be joking.

I've run many aliexpress chainrings over the years too, btw. I don't think the wear life is nearly as good as the other new rings i've bought, TA, shimano, etc. I don't know why and I still think they're quite good for the money but don't kid yourself.
>>
>>1886940
Also, I do get it, that aliexpress rings are WAY cheaper than alternatives, and buying them with shipping costs to many places is a lot easier too. If you ever buy stuff from different (not chinese) webstores though, wiggle, etc, just look out for heavily discounted chainrings. Those come up pretty frequently. That's a better way to get a cheap new chainring imo, if you're patient/lucky/not urgent or you have quite a few bikes.
>>
>>1886949
>With even numbered sprockets, only the teeth that correspond to the "stretched" half links get deformed, and by doing so, they work fine with the elongated half links. The alternate teeth don't wear as much, since they are dealing with normal pitch half links.
https://www.sheldonbrown.com/chain-life.html

some people run a fully narrow chainring with a wide chain like if they have a sram s300 with the stock chainring

>I don't think the wear life is nearly as good
i think it will be adequate, a phil wood cog lasts "forever" and a kmc e1/e101 chain lasts stupid long (see >>1886031), you could run the whole drivetrain into the ground or replace the chain and chainring at the same time because the chainring costs half as much as the chain

there is no fuckery whatsoever when the chainline is straight like on a properly set up fixed gear bike. the teeth just conform better to the shape of the chain. and see how fucking beefy the chainrings are while having material removed in strategic places, you gain a lot of stiffness for the same weight compared to a stamped chainring.

jesus christ just give it a rest. You always act like these shitty chainrings are the cutting edge of technology, like nobody else has ever machined a chainring before. Like they somehow unlocked the perfect machining pattern to make them optimally stiff and strong.
>>
>>1886856
ofc carbon is possible to repair and I will, depending on what I find It'll be a cosmetic repair only or I'll have to grind it out.

The coin tap test is worthless IMO. I still did it of course, and it came back inconclusive. Its naturally going to sound more dull than other spots since it has no clearcoat and exposed fiber cushions the coin.

Tests worth your time include getting an inspection camera inside and see if theres visible delamination or damage aswell as applying gentle heat on either side of the damage and watching on thermal how the heat propagates. Cracks disturb the heats propagation. In this bikes case I'll live with minor matrix damage because wound parts are as good as impossible to match or recreate visually.
