How do you stop a track bike without brakes?

Track bikes are slowed by resisting the forward rotation of the cranks with leg pressure — essentially pushing backward against the pedals. For gradual deceleration, riders simply reduce power and let the drivetrain slow them. For quicker stops, riders apply back-pressure to slow the rear wheel. In the velodrome, riders also use the banking to scrub speed by riding up the slope. Coming to a complete stop requires significant back-pressure and sometimes briefly skidding the rear wheel. This technique takes practice to master and is one of the key skills taught in track certification courses.
