How to Replace Tektro Disc Brake Pads

As some of you know, I bought a new bicycle that failed catastrophically within 3 days.. ​The gears were slipping and skipping right from day zero. It’s a 3 x 8 setup, and the shop mechanic claimed the manufacturer had mistakenly installed a 7-speed rear derailleur instead of an 8-speed. Whether that's true or not, he eventually swapped it out for a new 8-speed derailleur after my complaints....

Hello. I'm a beginner and I want to know how to clean a bike properly, do diagnostics test to make sure the group set is proper. And make sure my bike is pristine before and after every ride.

I have a Bontrager Race wheel with sealed bearings. While I have a lot of experience with wheels that have loose bearings, I don't have much with wheels that have sealed bearings. So here is my question; how do I get the axle out and the freehub off? Once the axle nuts were off, unlike a wheel with loose bearings, the axle itself still feels rigidly in place. I've watched some youtube videos ...

Hello. I bought a 2003 Raleigh SC40 recently. It is in very good shape but does show its age in areas. One is the 3x8 Shimano RevoShift twist shifters. They work just fine but are cosmetically challenged. The right rear shifter plastic cover has broken. I am inclined to replace both with new Shimano twist shifters. Hoping for suggestions, recommendations and cautions. Thanks for the help. ...

I have a bike in with an unresponsive transmission derailleur. Customer said it was hit with a stick that went into the spokes. There's no obvious damage other than wear and tear scuff marks. The battery is good and tested with the dropper. The shifter is good and working. The button on the derailleur does nothing. Single click, double clicking and holding the button. no response, no servo buzz,...

Hi folks - this is my first post! The seat post on my year old Roll 3.0 is doing something annoying. It has a bit of play around the shiny collar just above the post clamp (see photo). I was told there is a plastic sheathing inside. Can this be fixed or is the seat post all one assembly?   IMG_3153.jpeg (Size: 58.61 KB / Downloads: 728) ...

My friend is having this issue where the axle keeps slipping in the rear dropouts and hit the chain stay on the non-drive side.   IMG-20260418-WA0021.jpg (Size: 82.12 KB / Downloads: 88) This usually happens when a lot of force (climbing on a high gear or standing to sprint) is applied. It’s worse when the bicycle is loaded up with camping gear on the rear rack. Things tried th...

Hey all, I'd love some feedback on a repair issue. I just got the brakes bled and the first ride after was fine. But after one week of sitting idle, I took it out and the rear brake was suddenly making a horrible loud screeching noise when applied. Took it back to the shop and the mechanic showed how the two halves of the brake were not perfectly aligned and holding firm and there was oil leakage....

Hello everyone, I'm an older lifelong cyclist that recently had my beloved old yeti mountain bike stolen, and to try and fill that void, I picked up a 2015 Specialized Crosstrail (I'm riding more paved and gravel trails these days, my full-on mountain bike days are over!). The bike was in very good physical condition, apparently very lightly used. I was unable to ride before purchase, but it looke...
