Forum: Bicycle Mechanics

so my primary bike is out of commission, and my backup bike currently doesn't have any wheels... so i was wondering, if i put my wheels with the 105 cassette on the backup bike with tiagra shifters, will anything bad come of this (assuming i'm using the outer 9 cogs)?

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. ...

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...

How many miles does your bike mechanic ride each year?

I bought a new rim and spokes to build a new rear wheel. They calculated the spoke lengths and gave me two different length spokes: 293 for the right side, and 295 for the left side. However, the two spoke lengths look the same size when I stand them up next to each other, and they both seem to...

Hi all, Due to having a few problems with my left crank arm coming loose all the time (Truvativ Isoflow, square taper) I'm considering changing the whole set up. I've been looking at hollowtec type cranks, and the compatable BB's, but my bike currently has the non-external bearings set up. I...

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 have a couple of Campy G3 hubs off Zonda rear wheels. Can these be used with any other rims than Campy? For the price of a replacement Zonda rim I can just buy a complete wheel.

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?

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...
