How to Adjust Your Seat Height and Angle

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. ...

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: 686) ...

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,...

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: 85) 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...

Hello! I tried to change my Velowave ranger e-bike breaks and the lever would not have traction. I researched and learned I needed to bleed the breaks, I tried the top method with the cup with a break bleeding kit. Still had the same issue, I tried to use the syringe at the caliper but the hole was too small for any of the included adapters. Is it just trapped air in the calipers/line that is ca...

Will my conversion work? I have an old 2014 Giant Trance 1. It is a small frame. It is just a backup bike. It is still fun to ride and works well when a friend is or family member is visiting and bikeless. I hate sending things to the land fill or not being able to keep them repaired and running. I already replaced the fork a couple of years ago. I already found some parts and converted to a ...

Remember the Shimano law suit? Fortunately I had the"good model series" Thousands of riders trusted these components without a second thought. Now, the story has taken a serious turn. Shimano has agreed to pay an $11.5 million penalty after US regulators found the company failed to report a major defect in its 11 speed road cranksets on time. According to the CPSC, Shimano had received thou...

Hi there, I have a question in regards to either finding a replacement hub for my rear Mountain Bike or just replacing the whole wheel entirely. However when I went to a local bicycle shop (in China, that is so there are language barriers to keep in mind), upon inspection they claimed that the bicycle was too old to accept the replacement of their modern parts, which I honestly find hard to believ...
