SRAM Road 10-Speed Compatible
HollowPin™ Construction for Weight Savings with No Sacrifice of Strength
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.
