How to Remove Surface Rust on Chrome

Hello guys, I want to spend my weekends learning how to's and DIYs of bike repairing. I just have this dream of starting a bike shop in the future (may after this pandemic) Do you guys have tools suggestions to buy? Please let me know. I just bought RD aligner last week bec my brother's rd tilted. Thank youuu....

Crosspost from Reddit. I have a Cannondale road bike with a BSA bottom bracket (I think; I need the Park Tool BBT-9 to remove them) and a Truvativ Elita 2-piece crankset with splines. I've been having a creaking issue on the right (drive) side for quite a while now. It happens during the bottom 1/3rd of the right-side pedal stroke. There's also a little bit of play on the right side (i.e. I can s...

I am building a Mongoose MTB for my wife and the front cable pull is on the opposite side of the chain and I am having a hard time finding the right Derailleur for the bike. Any suggestions?...

Hello! I have a 2010 Specialized Allez Sport Triple bike and I would like to upgrade to an Ultegra groupset. I am super confused with the different options for derailleur (SS Cage or GS cage/Long cage) and cassette (11-25 or 11-30). If anyone has any input or can help it would be greatly appreciated. This is the bike: Specialized Allez Sport Triple This is the groupset I would like to buy: Ult...

Here's my repair situation: I have a what seems like a relatively nice road bike which I found for free on the side of the road years ago. Around three years ago, while cycling, there was a stuck link in the chain that caused it to jam. As I was pedaling uphill, the force caused the metal near the mount screw on the rear derailleur to shear. I have recently wanted to repair this bike. Unfortunatel...

Hey Everyone, New here and I'm currently taking on a small project on converting an old-school Fuji to a SS/Fixed flipflop. Firstly I want to thank you for your time and I'm looking forward to being in this forum as a regular 😁 So im currently having trouble figuring out how to remove the DT Shimano shifters seeing as I don't want to ruin the frame, but do want a nice clean frame look. is the...

I'm fairly new to bike repair aside from regular maintenance. Lately I've noticed by rear wheel has not been spinning properly--it's a Shimano 105 hub and axle. When I spin it freely on the bike, or when I spin it when the wheel is off, if feels clunky, like the axle is spinning into 'grooves' or 'notches'. I have two videos to show: On bike: https://imgur.com/a/SQX0I3P Off bike: https://imgur.c...

Ok, so I am not real fluent with bikes, however I am attempting to repair my girlfriends Next PowerClimber 24". The cog that holds the rest of the sprockets on the rear tire is threaded to lock them in place. The cog is cracked and the threads are not holding allowing the rest of the sprockets to fall off. I have attempted to find a place to buy this broken threaded cog with no luck. I am get...

My chain keeps falling off especially when I transition from 1st to 2nd chain ring. I also feel like I have to use a lot more pressure to shift from 1st to 2nd compared to going from 2nd to 3rd, which just might be me but I thought it was relevant to include. I am not super mechanically inclined so I can't diagnose an issue on my bike like this. Can you please tell me whats the issue and maybe how...

A short questions for those knowledgeable. I currently have on my bike a Shimano HG50-11-36t 10 speed cassette. Would the HG81-11-36t 10 speed be a direct replacement or will I encounter problems?...

Hello everyone. Are there any podcasts about cycling and more specifically bike mechanics? I have been learning more about bike repairs recently and would love to hear tricks from guys with know-how; need something to listen to during the work....

I was looking into wheels, just for the heck of it, and something is confusing me. I have a cruiser. The tires are 26" x 2.125" (57 x 559) The rim is 1.25". Cruiser wheels, online, are 1.75" The difference between a 1.75" cruiser rim, and the 1.25" rims I have, is approximately half-inch. I bought the bike, new, from a bike shop, and bought white wall cruiser tires for it. It had wide tires o...

Hi folks! I was directed here by the folks over at r/bikewrench as I hear you are a helpful lot! I have a beautiful old Sekine which I think after a little research is a SHC 271 from the mid seventies. Unfortunately I was in a pretty nasty accident last year and it was out of commission for a while. I was using it indoors on my trainer and slowly going about repairs, getting it road ready again wh...

Is that possible without switching out the hub, and is that possible at all? I have a base shimano groupset and I'm in the process of upgrading everything (I'm switching out the crappy tourney der for altus 9-speed, cables etc), and I would really rather switch out my freewheel for a 9-speeder also. Do you think it's achievable?...

  20200613_221949.jpg (Size: 64.32 KB / Downloads: 62) Hey everyone. I'm new to working on bikes and have been cleaning mine from using it at college. I replaced the chain since it was very stretched. The new chain was slipping a lot. After searching for why that was happening I concluded that I needed to replace my sprockets. The tool fitting rotates with the sprockets, so I think th...
