Jump Stop

Great device for STI Shift Systems
The Jump Stop is designed to make chain derailment past the small chainring virtually impossible by covering the entire engagement zone with a sturdy stainless steel guide plate. With a Jump Stop properly installed, you can safely adjust your front derailleur for maximum performance downshifts, and the Jump Stop will ensure that your chain lands and threads perfectly every time.
