I have been looking on Ebay for bike frames. There are a lot of them seem to have a good price. However, how would I know the particular one is DH frame, AM frame, Trial frame or CX frame?
I can definitely ask the seller, but I suppose this piece of information should be included in the description, but it doesn't. There is no information about degree of the angle of the head either.
For example, Specialized S-Work. Is it a AM frame or a CX frame? Would you consider a frame that is around 5 lb light weight?
