The PC 1031 chain benefits from new design changes for better performance. SRAM chain engineers developed PowerLock as a tool free, sure and consistent way to connect our 10 speed chains. While PL does not require special tools for install, the especially tight tolerances of 10 Speed drive trains mandated that each PowerLock is good for a one-time application only. Features:
PowerLock non-reusable connecting link is included
Compatible with SRAM and Shimano 10-speed drive trains
