I have an Ultegra 5-bolt Triple Crank with a 10 speed cassette, and would like to replace the small 30T chainring with something in the neighborhood of a 26T ring. Anybody have any experience with this that could recommend a vendor for the chainring?

Looking to replace my CDale Ultra with something lighter. Found something I like...the steerer is 7.75". By my measurement I have 8.00" from crown to the top edge of the stem with the spacers I want. Will the .25" pose a problem if using a compression plug? Thanks!

For a road bike with Shimano components, what book should I ask Santa to bring this year? Quality pictures & diagrams are most helpful to me. Any thoughts appreciated!

I am currently trying to find a cassette and chainset to suit my new build. My current bike uses an 11-28t cassette with a 34-50t compact chainset. I find that the lowest gear this provides isn't really low enough for some hills and I find myself having to mash a bit. How much difference would...

I know there is a company which takes bike chains once you fill up a box full of them, and they recycle them or make jewelery or something. They pay for shipping if you have a full box. I figured the mechanics would know the company i was talking about.

I've seen the bull bars, but I was wondering if any companies had made a bar end that has a drop down bar as well, so you get two extra positions. One higher and one lower. Links? Ta

hi, I'm not able to setup 53/39 Q-rings on my road bike with Shimano(6600) E-type derailleur. It always ended up with chain rubbing the cage. The cage has a groove along the chain and the chain moving vertically makes it very difficult to get the chain centered in the cage. Are E-type...

Anyone make something like this? I want to pull the cantilever posts from my disc and canti capable fork, but I don't want big holes there. I'd like to know if anyone makes an aesthetically pleasing frame accessory to put in their place.

I have a 1982 Trek 613 with SunTour Components that someone gave me two years ago. I ride it regularly but really enjoy my kids bike with brake lever shifters a lot. I've been looking for a new bike but a mechanic friend of mine suggested I buy brake lever shifters and the related components and...

Recently, I've been working on my old Windsor Carrera Sport, c.1980, getting it back in shape after years of neglecting it. I'm having trouble getting the RD to shift right, though. It used to shift "like butter" back when it and I were young. Now, it doesn't. The bike is mostly stock...

Would there be interest in a bike repair wiki? Some website where the whole community contributes to create excellent articles for everything from simple bicycle maintenance to the more complex stuff? I thought about creating one a while back, but don't want to create just another bike repair...

Hello and thanks in advance. So my problem is this. I have a small crack in the rear of the frame where the seatpost would insert on my 2003 Cervelo Soloist (alum). I have been reading in this forum about TIG welding as an option but was curious to see what other thought was the best fix. ...
