Gearing is pretty much restricted to the strenth you have. If you cant squat 405 chances are you wont do very well sprinting on a 96-98" gear. The problem with alot of sprinters in the amature ranks is they are on way too big a gear for their own strenth. Witch leaves you open to beaing beaten every time unless your really really smart. Sure you dont race at 170-180 RPM on the track, but the ability to over speed like that on a lighter gear means you body will want to keep accelerating when your on your race gear and youll have the stamina/ speed endurance to win. There are many more tactics and ways to win if you can spin your ass off and quickly accelerate as apposed to running a massive gear when you shouldnt be.

To get stronger in that sence you need to do alot of gym work on a proper shedual around your races.

A perfect example of a rider who has very high leg speed and has won because of it is Ryan Bayley.
