PowerLock® by SRAM offers a tool-free, reliable way to connect bike chains. Designed for 10-, 11-, and 12-speed drivetrains, it ensures a secure fit with precise tolerances. Note: Each PowerLock® is single-use only.
PowerLock® – SRAM chain engineers developed PowerLock® as a tool free, sure, and consistent way to connect their chains. While PowerLock® does not require special tools for install, the especially tight tolerances of 10-, 11- and 12-speed drivetrains mandate that each PowerLock® is good for a one-time application only.
