I'm 6 foot and the medium is too small for me, I should have got a large really. They are traditional sized frames, not compact or semi compact like most road/track bikes nowadays, so they are designed to be ridden large, with the seat down low, literally no more than 3 inches of post sticking out of the frame (words straight out of Nick Larsen's mouth). Unless you have unusually short legs for a person of 6 foot, definetly have a look at a medium or even a large before you buy one!
