How to Replace Cotterless Crank Arms

The bike, new, was $199 from an Amazon dealer, and it came with a load of great reviews and very few negative ones. That should be a warning to anyone looking for a new bike; the shills are out there. If anyone buys one with the idea of putting it together and going for a ride, they would be disappointed. Walmart bikes are better. Seriously! I knew that it would need some work because you do...

Hi All, Got a new Trek MTB and attempted to change the pedals. Unscrew the drive side pedal easily by turning anti-clockwise; all good there. This is where my noob mistake happen... Did the same by turning the left side pedal the same way (anti-clockwise) and over crank it such that the bolt is now just spinning clockwise and anti-clockwise without coming off. It's not loose.. just spinning in ...

Years ago, oil cans had long spouts. Even the throw away cans had long spouts, but makers started putting little nubby spouts on the cans which makes it hard to get into some places such as my bike derailleurs. To oil those I have to pour oil onto a screwdriver blade and let it run down. The cans of '3 in 1' oil I used as a kid, on my bike, had a long spout. So after digging around I found cans w...

Does anyone know of an aftermarket brake hood that (reasonably) fits Suntour GPX brake levers?...

First time doing this, I have to be 100% confident. Are there any risks and potential failures that have to be considered before switching the disc brake pads? I just bought the same pads I have had before, Shimano B01S resin. Will switchem th tomorrow hopefully. Nothing much can go wrong, right?...

Hi all. Couple more questions from the mountain biking beginner. What tool is the best for unmounting/mounting disc brake rotors? I currently have CUBE ZX20 32H wheelset if that helps. Also how can I fix a very slightly bent rotor? It's not very noticeable but still bothers me with that sound ... squeeks against the pads once in a while....

I just wanted to show how I rescue rusty bits and pieces using Evapo-rust. does a decent job for just soaking, letting it work, then rinse and lightly scrub and then off to the bench polisher. this is how to start off and I will post pics of the finished bolts when complete. I think you will be pleasantly surprised at the results. ...

I am the original owner of Cannondale Quick 2016, which I have purchased from one of the Authorized Cannondale shops. Everything went well to begin with, and the bike rode very well. But one day, while cycling on a straight, tarmacked road, all of a sudden my front wheel begun to wobble uncontrollably; the wobble was strong enough to set me straight under a heavy traffic, it was a very near miss. ...

xposting this to a few forums as I truly don't know where to start! Link to current setup https://imgur.com/a/Uxwkd54 I come from a car repair background and am trying to learn more about bikes. I have a bianchi I use to commute, and an ol' fuji single speed I'm using as a learner. Just toyed around on the brakes a minute and one part broke (old). Yay! New parts! But how do I know which caliper...

Hello! Recently I was "given" an old Peugeot bike. Checking its decails and the number on the shift derailleur I found out is from 1982. The brakes and brake pads are original. I might not replace the brakes just yet, but will for sure replace the pads since they´re old an hardened. Do any of you know which pads might suit this?   BRAKES.jpg (Size: 149.58 KB / Downloads: 10) ht...

Hi. I have Shimano HG601 chain 11-speed and I want to add the master link to it. Watched some videos but I have to be 100% sure, that is why I hereby present my brief plan: 1. there is a black link in the chain 2. I use the chain tool to push that black pin out 3. then I add the master link 4. finish up with using the special tongs to press that master link into the chain Does this look like a g...

Almost finished by bike upgrade, only to find my freehub is too small for new cassette. Is it possible to upgrade the freehub from 10 speed to 11 speed or do I have to buy new wheels? Wheels are Shimano RX05......

Hiya, on tour at the moment. Realising from hand and wrist pins that my flat bars are a bit low for me. I opened the little cap and undid the hex bolt, but the stem seems to have seized to the frame. Any tips on unseizing it without damaging it? Someone suggested wd40, which I don’t have. Would regular chain lube (tf2 all weather) overnight work?...

  IMG_2496.jpg (Size: 203.54 KB / Downloads: 7) asked this question over on /r/fatbike and i'll ask here as well: i bought a used fat bike, a mongoose argus comp, that was upgraded with a rockshox bluto 100mm suspension fork. I have a full squish XC bike, and with no real need for the supsension on the fatbike, i purchased the stock mongoose alloy rigid fork ($50). I am planni...
