What are you riding and how much are you pulling?
There are a lot of threads on here about about weight limits, frame materials, spoke count, etc. Usually a few (or more!) awesome forum members chime in with their experiences with different equipment at different weights. I thought it might be helpful to have a thread that would serve as a sort of clearinghouse for information about what kinds of bikes people are riding and at what weights. I know I'd find it interesting to see the breadth of equipment and experience on here.
I'll go first:
I'm riding my one and only road bike (so far!) a 2002 Specialized Allez Elite Al frame. I busted some spokes on the stock tires when I was young and 225 pounds. No now am riding on a set of 28 spoke (will check and confirm) wheels at around 255-260 with no problems (except that I can't get back down to 225).
