Riders who don't have any experience on shorter and tighter tracks are at a disadvantage to riders who do have experience on such tracks. If you are going to race track, you need to gain as much experience as possible on a variety of tracks. When going really fast through such turns, you need to pull yourself a little forward to get your weight more over the pedals. This causes the G forces to pull your weight more into the pedals which helps you maintain a higher speed through the turns. It also requires more fitness to ride the turns and move up the track in mid turn.
Improved fitness makes it easier to pass or make upward tactical moves in the turns.
The hieght and steepness of the bankings also effect your racing tactics. The higher or steeper the banking, the faster a rider can accelerate on an attack and the less effort has to be expended to make an attack saving energy for the break. In their lack of knowledge about velodromes, they think that a more shallow banking is safer. They are very wrong. If a track is not banked properly, it is very dangerous to the racer.
