i ride a 58cm Fuji 1.1 Track at Frisco Superdrome. it has a 120mm stem, and stock OEM wheels. when i am going full tilt in a sprint, the bike feels really twitchy at the front end. i think this causes me to instinctively dial back speed a minute amount. and when i put an 88mm rim tubular on the front, pressure at 130, this condition seems even more present.
any ideas about what might be going on?
