Ok, im looking at a frame on performance bike and was wondering what their sizing was? The frame im looking is said to be offered in XS through XL. In thepicture of the fram, there is a sticker on the seat tube that says 51. I am assuming this means 51cm. With that being said, I want to think that is a XS seeing as how very few people make anything smaller. So, 51 being XS, a Medium in theory would be a 55cm which is what I ride. Does anyone here know how they size their frames? I am checking out the Performance aluminum road frame.
I know I know, this is the SS/FG forum but I know some of you guys buy from there so I though I would try here first.
Here is a link to the frame. If there is no clear cut answer here, I will just email performance.
