Why do brakes squeal when wet?
>>
/n/ewfag here. Do bike people just mostly buy from amazon and ebay? If I want to buy a gun or gun parts or ammo I can easily find the best price online. I'm having a hard time doing this with bicycles.

For example; I need a new wheelset for my hybrid bike because I want to change to disc brakes. Most sites, including Amazon, might have 1 or 2 sets for 26" wheels. I don't want to go to a bike shop. I live out in the country.
>>
>>1338893
i mostly use wiggle & chainreactioncycles (same company). Sometimes amazon or local nz retailers. You can probably find what you want on bike-discount.de, bike-components.de or bike24.com (german companies), which are less sporting focued. get a dynamo hub wheel.

Do you have mounting points for the calipers on your frame/fork?
>>
>>1338798
hoooo buddy, chain is COMPLETELY worn out. Chainring is probably fucked too.

All bike chain is half inch pitch. You wouldn't see this by putting the wrong speed chain on a bike.

(yes, pedantic nerds, I am aware of the Dura Ace 10mm pitch system from the mid 70s. No one is ever going to "accidentally" install something like that)

>>1338893

holy fuck, no. Just a hellscape of stuff with shitty descriptions being sold by who knows. Why does anyone shop for anything on Amazon anymore?

If you're in the USA, Universal Cycles is my go-to. Jenson USA is pretty ok, so is Tree Fort Bikes.
>>
>>1338904
actually you could see something like this from putting a 3/32" chain on a single speed 1/8" drivetrain.

This isn't that case, obviously, and you likely knew that, but regardless.

I have a pair of tubeless ready wheels. Apparently they work fine with tubes, but they are hard to make work. What ends up happening is the tube around the valve is too thick for the tyre to get under/around and therefore it doesn't seat on the rim properly when inflating. It doesn't happen anywhere else just near the valve. I'm using standard clincher tyre. So, how to make work?
>>
>>1338798
probably means the chain is too short, but you'll need to replace it entirely at minimum and likely change the chainring too

I'm not sure if I am understanding you correctly, but is a bit of the tube getting stuck under the bead right near the valve stem? If so, push up on the valve stem to push the tube further into the tire. Obviously you will not want to have a nut on the valve stem while you're doing this. This is actually good practice to do in general whenever installing any tire on any wheel, because near the valve stem is a common place for a tube to get pinched under the bead during installation.

The chainring in that pic is extremely worn out. That bike is going to need new chainrings, a new cassette, and a new chain. (possibly new rear derailleur pulleys too but that's generally not much of an issue) They are very worn out. To prevent things like that from happening in the future, the chain should be replaced once it reaches 0.75% stretch (a bike shop can measure it, or you can buy your own chain checker tool). This will generally mean replacing a chain every 1,000-3,000 miles of riding but it varies a lot based on many factors.

That same effect (the chain not sitting on the teeth properly) could theoretically also be caused by a chain that's too short or by a chain that's not compatible with the chainring or by bent teeth on the chainring. But in this specific case the appearance of the chainring teeth make it obvious that it's just really worn out components.

>>1338893
Ebay often has good selection, as do various online bike shops. I sometimes do a web search for the specific product I am looking for, and see which of the online bike stores has it cheapest. I'll also compare to ebay prices.

In your specific case you probably can't change to disc brakes because your frame and fork probably don't have disc caliper posts.

Both my local shops did demos this week, tried a Giant Trance29/Anthem29, and Specialized Stumpjumper 29 (and all the full-sus eBikes because draining the batteries on them is hella-fun).

TL:DR: Giants felt meh, and Spec. felt lethargic. I'm not racing, so would an XC 27.5 be the better setup for trails, or should I give 29 another chance?

Those are for mounting racks/fenders. Disc brake mounts will looks like this, the ones for your rear wheel are the same but on your non-drive chainstay.
So no, you cannot put disc brakes on it. If your brakes feel like they don't stop well, get some better pads or even calipers. V-brakes are pretty cheap. If the noodle on your front is one of those stupid springy ones, replace it with a normal one.

They're extremely high quality and they last for ever.

bar-end is also mostly aimed at tri race bikes and both are low-numbers niche products.

If you want some cheap there are loads of old ones floating around.

Fuck off to >>>/o/ if you want a motorcycle. If you want an actual mountain bike, it really depends what kind of riding you want to do. XC bikes are nice for long rides on mellow terrain. They're easier/faster for climbing. Longer travel bikes are better for more technical terrain and faster descents on the downhills. 29 is more popular for mellow terrain and XC bikes, whereas 650b (27.5) is more popular for trail/enduro bikes and more technical terrain. My enduro bike (160mm travel) has 26" wheels and I love it, I have no desire to go up in wheel size. If I was going to be doing a 200km ride in the southern Utah desert (that is, long distance on flat mellow terrain) then I'd like a 29" hardtail XC bike, or maybe even a bikepacking bike like a Fargo.

Its function depends on what it connects to "near the handlebars" tells us nothing, trace the cable

It's connected to the left shifter and disappears into the frame body

then it adjusts the cable for your front derailleur. Don't fuck with it unless your front shifting sucks in which case you should watch a video on how to adjust it before you do anything. Simply twisting it blindly will only make things worse.

My BB is beyond worn out and needs to be replaced but the cranks are seized to the square taper so I might have to cut the BB spindle and possibly get new cranks. I was thinking of going full autism and going external BB but have a hard time justifying spending my bike's cost on a replacement whole new drivetrain without knowing the benefits of external vs internal BB.

Fresh drivetrain with external BB will cost $200. An internal will be about half that if I need new cranks, $50 if I don't. What I'm wondering is, is external BB better than internal ISO square taper? This bike goes to hell and back. You all know I'm a courier so it sees rain, snow, salt, sand, everything.

tldr; internal or external BB?
>>
>>1340289
I wouldn't go with an external unless you end up needing both a new crank and BB. Even then, I wouldn't necessarily spend the extra money unless you want some new parts anyway. I'm assuming you don't make a ton of money as a courier, because I sure as hell didn't. I tended to get more mileage out of a square taper than I did out of external cups anyway.
>>
>>1340289
I had the exact same problem when I worked as a courier. I splurged on the external BB. It wasn't worth it. It made no difference at all.

Thanks for additional feedback, will stick with the low cost more durable option then. This is why I asked

>>1340201
Assuming you can't get it to a trusted mechanic, tap test and visual inspection. Focus especially on the portions stressed by the wheel that hit the bump when you heard the sound. Eg, fork, headtube, especially the headtube/downtube joint for the front wheel, rear triangle for the rear wheel. Seatpost, ect.

>>1339283
Smaller.
>>
>>1340201
About all you can do is a thorough visual inspection, particularly around bends like the headtube area, as that's where carbon tends to be weak due to voids in the layup. The coin tapping test is kind of a meme because you need to know what a bad spot sounds like. Xray+ultrasound can expose most internal cracks but unless there's a carbon repair place like Ruckus or Calfee near you you're probably not gonna find anyone with the equipment.

I've ridden square taper my whole life and never had any problems.
recently needed to re-gear to a compact crank. a guy on ebay had one for cheap but it was hollowtech, but the price included the bb, so I copped.
I honestly can't tell any difference. the bb weighs a little less but I don't notice in practice--then again, the new crank weighs a little more than the old one, so maybe that's why. really, I can't tell any difference at all. so it's good, but there's no reason to shell out a lot of money for one except gram shaving, I guess. IMO.
you need two new tools to install it, so that's wack, but my co-op had them, thankfully.
this is Miyata 312 guy, btw.
>>
>>1340446
Ey, 312 touring Miyata guy, that's a little disappointing for how much they charge for external BBs man. I'm assuming the only reason to have one now is prestige... Change of topic, the Miyata 912 I was eyeballing was sold before I could gather the money for it. Sadface

Chain is insanely stretched, this causes the teeth mismatch. You need to replace it.
The chainring is worn out too, also replace that.

>>1339159
>chain too short
No, a too short chain would still fit in the teeth. You get in trouble with the rear derailer slack with a too short chain.

>>1339214
A worn chainring cannot cause the mismatch, the number of teeth on the diameter is still the same.
It is the stretched chain.
>the mismatch could theoretically also be caused by a chain that's too short
wrong, see above

>bike needs a new casette
How would you know? It's not on the pic. If the casette has as many miles as the chain and chain rings you are propably right.

10 speed casette is already quite a lot.
The difference between the cogs just gets smaller with more cogs on the casette.
The total available transmission range is the more interesting thing and thats indendent from the number of cogs on the casette.

I have an 11 speed casette and I find myself to shift more often. I wouldn't go higher. It also requires a finer tuned derailer and a smaller chain, I don't really see the point.

>>1340808
RTFM
>>
>>1340808
Hold both shift switches on the right shifter for a couple of seconds and the light on the junction box will indicate the battery level for you. Solid green = fulll, flashing green = 50%, solid red = 25%, flashing red = dead.

With Di2, it should shift the same all the time unless the derailleurs themselves have changed position. So unless the front derailleur gets bumped and becomes crooked or the rear derailleur hanger gets bent, you shouldn't have any problems. If it comes with the little bluetooth guy, download the app on your phone so you can update the firmware periodically yourself. Not much other than that. I doubt you'll have to charge it before riding, but check it anyway. Enjoy.

Those 2x5 stuffs from the seventies? Answer remains - there is no sensible ( cost effective ) upgrade path to those things.

I'm thinking about a long (at least 1000 miles) east-west bikepacking tour. Would pic related make it possible to 'sail' if given a headwind? Would it be retarded to try this on a stiff/aero race bike? An article I read showed that pannier positioning could have a drag effect equivalent to carrying an additional 20kg, so why should I not commit to full aero (vs prioritizing comfort) if I were only doing 70-80 miles/day?

What should I do if I'm bottoming out my MTB suspension while running 20% sag? Increase air pressure/stiffness and run even less sag? Or just bottom out and not worry about it?
>>
>>1340866
>>1340866
Bottoming out is fine if it happens rarely ( as vague as that term is ). If it happens too often and you are already at 20% sag then the next course of action would be to increase slow compression.

It also depends on how much travel your suspenson has. 180mm forks are run at 25-33% sag. 70mm forks are often happy with 10% and my 30mm fork adjusted for road uses no measurable sag at all.
>>
>>1340859
Closer spacing has always been a thing, yes, but now we're getting closer spacing in the gears that people mostly spend their time in along with more range for climbing gears, along with closer spacing in those gears as well. 2x11 and 2x12 just requires more precision in setup, which is made easier with electronic shifting. eTap in particular is really easy to setup, and I imagine that future generations will completely automate what little challenges are left and make it 100% plug and play, so long as you stay within the system on all components.

All that is true. Except it was already possible on 2x10. And if you wanted all of that range, you went with a triple.

3x10 gets you more usable ratios then 2x11. It also allows to use, for example, 11-23 cassette and still get all that range.

On the other hand - 11 added a host of problems, and in many cases, a loss of gears, not gain. All that hinges upon - do you really need that extra range.

If you don't, then ( using 11-28 as an example )

Replace 11-28 10-speed with 11-speed. Now all lower gears are shifted 1 position to the inside. Hello chainline issues.

Replace 11-28 10 speed with 11-speed 11-32. Now you have a 32cog you barely, if ever, use.

This "moar raeng" mantra ends with cassettes worn as pic related. High end dead, low end useful and the entire thing being ridden as a 2x5 most of the time.
In the end - you get pic related. Tons of cassettes

And for the doubters. 10 and 11 speed cassettes side by side ( chinesium 11-42 and slx 11-36 ). It is clear that 11 is just 10 with an added cog. Which introduces a ton of problems.

I've gotten 11 speed to work fine only with careful management of the chainline on 1x system. Otherwise something always goes sour.

Dude what are you talking about? Set up a 1x11 system as the manufacturer recommends and it works fine.
>>
>>1340885
I'm talking about trying to get a 2x11 to do as well as I could on 10 and 9 ( and 8, and 7 ). Regardless of what you do - the reduced tolerances coupled to the need of dealing with a wider cassette always make shifting to perform worse on the extreme ends of the cassette. At some point. Its inevitable.

On 1x it works because you don't need to deal with an FD - those N/W rings really work well.

Thanks Trybo, I already made my mind on sticking with the more sensible BB for my application.

I did the math today on my 2019 2x11 roadie vs my 2017 3x8 cross bike
- number of individual rideable gear combinations with non overlapping transmisson ratios
- total possible transmission range

The ratio value represents how many revolutions the rear wheel does per 1 crank turn.
Red cells mean the theoretic gear combinations cannot be used due to chain angle.

I found that I have more individual rideable gear combinations (15 vs. 13) and an equal total transmission range on my 2x11 roadie. (3.4 range width)

My conclusion was that 3 chanrings are pointless because you get the same range or better with 2.
You would get the same range width by removing the middle of the 3 chanrings on the cross bike.

I agree with you that 11 speed is too much though and 9 or 10 is peak sanity for the reasons you mentioned.

There are a lot of hills in my area so I need a broad range, uphill and downhill.
>>
>>1340912
What do you mean? Do you want to buy used?
Used bikes are old and disk brakes are a fairly new thing on road bikes so they're hard to find.
Cheap suggestions for new bikes:
- Vitus Razor
- Marin Nicasio
- Marin Gestalt
- Cube attain disc
- Triban RC 500 or 520 (semi hydraulics)

I eventually also bought a new one because I couldn't find discs on a used bike.
>>
>>1340914
Your mistake is subtracting the low end from the upper end for the "range width". The important thing is the overall percentage increase. If you divide your numbers you'll see:

4.4/0.9 = 4.89
4.6/1.1 = 4.18

So your 3x8 actually has more overall gear range. I would also recommend using a website like http://gear-calculator.com/ instead of custom Excel sheets.

And yeah, wide range is retarded for most riders who aren't going to be doing huge climbs, or who would be better off with a subcompact crank anyway, but there's a certain set of riders for whom it makes a ton of sense, and for another group of riders who really want to be like that other certain set.

the aero from bikepacking setups does make a big difference at speed on the flat
the aero from panniers really slow you down. It's almost as significant as how much the weight fucks you on climbs.
It's definitely worth going for if you want to be fast

you just don't get nearly as much space and it's trickier to pack, so you'll need to have expensive gear (inflatable pad etc), ruthless minimalism, not go long between places to buy food/ get water, and maybe not cook or camp or both.

Yes you absolutely could do it on any road bike, especially if you already have one, but with the extra weight and how it's often best to ride b roads or gravel, you'd still be better off with fast 28-35mm slicks, so an endurance road bike with wider tyre clearance or a cross bike or something is probably more ideal. With most road bikes you'll also lose the oversized cages on the forks bit of a bikepacking setup, because you can't clamp to carbon and they won't have the 2 mid fork bosses like some meme bikes have.

First of all - you are comparing apples/oranges. It would be fairer to compare 2x11 with 2x10 and equalize over range or

Second of all - you are not equalizing for the extra width of the 11 speed cassette - which makes your setup kind of odd - 28 can be freely used with more gears then you allow, but by the same token, 34 should disallow more cogs.

If we use the aforementioned gear calculator we get - pic related. You get 16 usable gears on 2x11 and 20 on 3x8 if every factor is equalized.

>3x sucks and I've never met anyone who actually likes it, especially over a wide-range 2x.

You should preface it with: Overwhelming majority of cyclists are not using the FD in an optimal fashion.

That is because all that nonsense talk about chainlines and cross-gears and duplicates. So people use the FD _WAY_ too often.

Anyhow - all this talk triggered me into finally ditching the 1x11 on my roadish bike. Now I rock 2x10 with 50/39 rings and 11-23 cassette. Kind of steep for me, but whatever. We'll see how it goes. Pic related.
>>
>>1341486
>you are comparing apples/oranges. It would be fairer to compare 2x11 with 2x10 and equalize over range or

derp.

...equalize over range or selectable gears. On a triple you either get more gears to select in a given range, or more range with the same gears.

3x10 with 52/39/30 rings and 11-28 cassette gives you the same gears that 2x11 52-39 with 11-32 does and adds some really low gears to the mix. As a bonus - you avoid the awkward 16T gap between rings that compacts have.

I have a 50/40 with a 12-23 9 speed and I fucking love it. 1t gaps on my most used gears. Mostly spend time on the 40 since I'm commuting with lots of stops. Rarely drop below the 17 cog, but I'm in flatland.

>28 can be freely used with more gears then you allow
I was refering to the manual of the bike and it specifies the useable gears like this. And I can confirm it this way - 28 chainring on 6th cog and above has a too crooked chain.
Don't forget the 2x11 has a narrow chain and cogs + the 2 chainrings are more centered to the casette because the chain ring stack is narrower.

>You get 20 useable gears on 3x8
No, not quite due to crooked chain and redundant transmission ratios. I subtracted redundant ratios.

>On a triple you either get more gears to select in a given range, or more range with the same gears
Or no benefit at all. Recall what I said earlier that you could dismount the middle chainring on a 3x and have the same range.
This would also allow for more selectable gear combinations with a less extreme chain angle because the chain ring stack is narrower.

Normal riders just buy a complete bike with warranity and where everything is matched.
Building up bikes from frames is more like a hobby on its own outside of normal riding/competetive riding (except high end tier)
If the frame isn't high end or fancy italian its not worth so much.

New parts do depreciate really fast. The only new things I buy for bikes are cables and chains. I get all my other stuff from cheap used bikes that are not in roadworthy condition, but still have some good parts. For example, the old roadbike I bought for 60$ a week ago had a nice brooks saddle, good brakes, good wheels and good tires and tubes. Plus I get a nice frame, fork, stem, bars, etc.

Manuals are a reflection of whatever the writer of the manual thought was a good idea. How do you judge "too much"? I literally posted, in this very thread, a result of gear-calculator which equalizes over deflection angle and it allows 16 gears on 2x11 and 22 gears on 3x8.

>>1341737
>Don't forget the 2x11 has a narrow chain and cogs + the 2 chainrings are more centered to the casette because the chain ring stack is narrower.

And once again - in this very thread there is a picture - side by side, of 11 and 10 speed cassettes showing clearly that 11 speed is wider by one cog then 10speed. Which in itsself is a touch wider then 9, which is almost identical to 8. You want pictures?

>>1341737
>No, not quite due to crooked chain and redundant transmission ratios. I subtracted redundant ratios.

With redundant ratios out, you get something like 12 ratios on 2x11. Redundant ratios are a meme anyways. You have a chainring, you have a cassette. You use that chainring for as long as it is sensible to avoid using the FD. Deflection angle - because of wider stack, is more of an issue on 11+ drivetrain, then it is on 8.

>>1341737
>Or no benefit at all. Recall what I said earlier that you could dismount the middle chainring on a 3x and have the same range.

But range does not tell the whole story. If we were all about range, then 2x2 would be a thing. Its not, because we also want reasonably tight spacing between gears. Having triple-sans-middle type of gearing makes you end up with a massive 20T something gap between the chainrings. 16T on compacts is bad enough.

>>1341737
>Well I'm comparing bike gear shifts with their individual rideable gears and possible transmission ranges

...and a triple will always give you either more range, or more gears within a given range.

A bike loses 30% of its value the moment it gets sold. Then its value drops by 50% each year since its model year.

Some high-end boutique parts hold its value pretty well - but even then. In three years expect to get a third of its sticker price. Or less.

Then yeah, you can keep the current crankset. Though I've had a couple of friends who ride fixed gear bend road chainrings, due to all the torque you apply since you're stuck on a heavy gear all the time.
In any case I'd recommend just buying a cheap SS and keeping your hybrid for when you inevitably want/need gears again.
By the way, narrow-wide chainrings have nothing to do with SS, they're for 1x drivetrains. You can't drop the chain on a SS

Since I had the bike up high on the stand maybe it's just the bearings and I never noticed it. I can;t fathom how sand would have gotten in the bottom bracket after only ONE ride, 20mi.

I noticed the chain was dirty so I wiped it with a shop towel, same with the chain ring and cassette.

It sounds like there's sand rubbing together inside the bottom bracket. There was a bit close to it but it looks like everything is sealed up.

Again I never had my face directly infront of the bottom bracket while rotating the cranks so maybe it's always made that sound and I've never noticed.

Has anyone tried strapping one of these to a bike?
It looks stupid as hell and will probably catch wind like crazy, but I have a specific use case for it.

During my work commute I'll have to start carrying work related stuff that is sensitive in the rain (and too big for a pack). The main options I've been considering are this, a bike poncho, DIY'ing some kind of waterproof pannier.
Considering how cheap they are on aliexpress, I might just buy one with a poncho and test them both.

Opinions?

What do you mean about the material? It'll fall apart or be itchy?

>>1342325
change the way you absorb the impacts unless you want to regularly be familiar with rebuilding your shocks and replacing your bearings
>>
>>1342405
Should work just fine on an upright bike at low speeds
If I were you I'd just strap whatever you're carrying to a rack and cover it with a waterproof tarp.

If I like the Fizik Antares R3, would an Antares 00 still be comfortable while wearing casual clothes with the minimal padding it has, or is it designed to be used with bibs exclusively?
>>
>>1342522
Because your shocks will act like they're mostly locked out except for the big hits.

i dont know what i can really do, im not hitting drops im just descending pretty quick. i did my first xc race the other day and the course went through 2 enduro stages that i compared my times to and had i entered enduro i would have placed top 5. more suspension isnt really an option because my bike would gain weight which no one wants in xc.
>>
>>1342560
although i have been considering it, if i have a pretty high end full suspension bike that came with 100mm how much could i add to it without destroying its handling? i guess 120mm would be safe but could i do more? maybe 150mm and run like 35% sag?

I'm thinking of waxing my chain since it seems to be better than normal lube and since I got a new bike I wanna take really good care of it. When i got the bike I applied some ceramic lube becasue I was unsure if I should or not, better safe than sorry.

This chain doesn't have a quick link so if I take the chain pin out (looks like a grey disc and larger than the others), do I need to buy a new one?

I also don't own an ultrasonic cleaner but I could do the bottle shake method or some other but I need to get it perfectly clean.

My main concern is getting the chain off and back on, I should be able to handle everything else.

What tools do I need to install them? All I have is the chain tool on my crankbros m17.

Also reading some reviews some people have expressed concern about the rub on wax not getting to where it needs to be but all the reviews seems pretty good.

Maybe I should just hotwax it?

I use MSW and really like it, there's nothing like racing on a freshly waxed chain. I use pic related to install the quick links, some might say it's overkill but I want to be absolutely certain I'm locking it in with everything straight and flush.

Yes I know and I am describing what Chad really does. Maybe it just looks like 40 to the virgin observer.

So to install a quick link I basically just remove the link with the master pin and install the quick link there?

These are the links I use, I've never used the KMC ones. They might be fine, I can only give advice on what I have experience using. Just make sure you've got some wire coat hangers or old spokes that you can bend to make the chain swisher thing. A thermometer for the cooker is a good idea too, supposedly letting it get up to 190*F is 'correct'. And make sure you let the chain heat up with the wax, don't melt it and then dunk the cold chain in, your temp will drop way too low. Also don't cut corners when you're degreasing the chain, you only do that step once during the entire chain's life so do it right. And clean off all your cassette cogs and chainrings from your old lube before you put your waxed chain on, this is the only time you'll really have to do this. Have fun anon, wax is great.

free bike!
From the info on the kickstarter it looks like the only useful function of the app was the lojack, which worked only by having enough on the road that it would pass another one to trigger a notification. Other than maybe the maps it all draws from a dedicated server. You might be able to mess with the app to regain some function, or at least access the onboard tech to rig up another lojack, no gps and bluetooth is limited away from you, but perhaps they just stuffed a raspberry pi into a bike frame, I doubt it can be too complicated even if not.

Regardless it looks like a good bike, if it is not too heavy. I also ride a single speed but you may want something more versatile, I have not had any problems with mine.
>>
>>1340640
This person thinks it will actually be a better ride:
"Back to our testing, riding the forks on bike that were designed for them, of course feel great. Now we are putting them on bikes that originally were designed with the 51mm offset forks, bikes like the Yeti SB5.5, Evils The Wreckoning, new Devinci Troy and Santa Cruz Hightower LT, we found these bikes do have improvements with reduced offset forks. Does it handle like a new bike, no. But it does help with that cornering ability, straight line stability and also slow down the front end feel a bit".

very old ones will be serviceable
modern, no
new cartridge replacements are cheap ~$20 and saves a lot of hastle cleaning, repacking and adjusting bearings, which may not even be good.

if your bike is old you could try service it first. but you should be able to find a cartridge replacement for even old standards.

From my experience re-greasing is pretty useless.
Just get new bearing. Those aren't designed to be serviced. Some even come with metal caps, which can't be removed without damaging them.

Btw, why kick scooters (including electric ones) use industry standard deep groove bearings, while most bikes use weird 18-th century abominations like pic related?

Older model Onguard Brute for locking rear wheel/frame, and some kind of cable thing for front wheel
might get another u for the front wheel instead, would be more secure and probably smaller. i only need a little length anyway.
keys only, combo is slower and has security issues
>>
>>1343094
If you're going to deliver, it's more secure to get hooked up at a place like JJ, Potbelly's, some pizza place, or your local courier company but with the food places, know that your duties will be more than just delivery when it's not busy. If you need to have a versatile schedule, one of the delivery platforms is not bad if you can sacrifice security. I'd still suggest getting onto a platform, I know a JJ courier who also runs Caviar on the side. If you're going to strictly run a delivery platform, find the one that dominates your city (all cities are different) and sign up for that one plus a second platform. Most importantly, if you run a platform, reserve those scheduled shifts, you'll get delivery priority and helps you build a rhythm mentally. Start slow and pace yourself because you'll be riding for hours. If you don't, you'll burn out. Fuel yourself good and drink lots of water. Last, don't splurge on shit you don't need and save extra for taxes.

I've been doing this hustle for about 4 years. I've been on GH, PM, DD, and Cav but not UE. Right now DD has been booming in my city so I've been almost mostly on that. It's not bad if you know where and when to work, I've been pulling a consistent $17-20 an hour, more or less. There's good days and bad days, build financial cushion for bad days. Haven't gone to a legit courier yet because I need to be able to make my own schedule but once I can, I will.

Don't worry too much about your setup, that'll come as you gain experience. Feel free to ask any more questions. I'm sure others are or have been couriers here too.

Def getting a chain tensioner, hub spacers and a ss rear cog
Apparently you can use what's called a ghost cog to sit in the chain to tension it, but I'm not brave enough for that
>>
>>1343444
There are basically two generations of Campag 11 Ultra mechanical. First gen ran until 2014/2015, when it was replaced by what they called Revolution 11, which made some major changes to front shifting, eventually introduced hydro disc brakes, made the hood shapes nicer, changed crank spider to pig disgusting 4 arm, and most importantly they totally broke compat with previous gen and with Powershift stuff. Used to be you could get PS everything except shifters, and pair with Chorus+ shifters. If you were really nutty about chrome, you could toss Athena levers onto Chorus bodies if you couldn't find the rare first-year Athena Ultrashift silver. But that's totally no bueno now.

Personally I'd go for Chorus 2015+ because I like Ultrashift so much. Pre-2015 is fine too, but parts availability outside of fleabay will suck.
>>
>>1343498
Thanks. I thought this used bike I want to buy had full pre 2015 Chorus, but apparently it has Chorus brakes and shifters, Centaur carbon brake levers, Fulcrum crank and Athena everything else. That, plus the fact that it has a ~53cm top tube (I'm 180cm, 83cm inseam), for 1500€ is making me have second thoughts.

I had to get my rear tire replaced and I noticed it says "inflate to 40 PSI." Is this the absolute limit or can I inflate it to 60 like I used to?

>>1343550
there should be a range somewhere on the tire, google it if you can't find it
>>
>>1343550
It should be fine but if it says that there's a reason. Probably the new tire is wider than the old one, and thus the recommended pressure is lower.

Do you have any experience with using the Kojaks? I'm looking more for real-world experience than BRR's testing, and most people who have used the Kojaks are positive as far as how well they roll, one of them going so far as to say they're almost the same as Compass RTPs. But I'll likely go with the MSs as they're a known quantity to me.

Those bikes are pure shit, so obviously the parts you could get from them are pure shit too. And they tried to make them as non-standard as possible, to prevent bike thieves from stealing parts of them.

No. Modern forks, of any brand, are built for the usual fair weather. The usual problem is thickening of the damping oil - it needs to be replaced. Lubrication is a problem - full oil bath forks are long gone.

Regardless - even the best prepared fork is going to be much less sensitive in the cold. Up to freezing solid.

They could be contaminated from stuff on the road, your hands or your tools. If its not too bad take clean sandpaper and rub them down a bit. It could also be that they were not bedded in properly. Theres tutorials on how to do it properly. Also check the caliper and disc bolts are tight.
