Anti Chain Suck Adapters by N-Gear 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.
