I currently ride a 56 cm touring bike for commuting. This bike is very comfortable in the "French touring" manner, that is, low seat, little seat to handlbar drop. I have the opportunity to buy a 53 (54.5 TT) road bike. I would use this bike for fast recreational rides and possiby some amateur racing. Would this bike be too small or just about right for this purpose? Additional info: I'm 5'9.5" tall with a 33" cycling inseam. Thanks.
