What is it that characterizes the Keirin track bikes other than their certification? By this I mean what was and is the intended goal of the Keirin bikes? Are they lighter or stiffer or just more carefully constructed or do they have special dimensions that are peculiar to them? Are our own KOF builders up to building these type of bikes or is there some special training needed? Why do these bikes have such an extraordinary rep over say the old British track bikes?
