No weakest link. SRAM's 11-speed chain features the PowerLock® connecting link — the only secure tool-less attachment device for a SRAM chain. No tools necessary to install. Allows for quick and easy maintenance.
SRAM chain engineers developed PowerLock® as a tool free, sure and consistent way to connect our 10-speed chains. While it 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.
