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. - Compat - Speed (CN): 10s - Chain connector type: PowerLock - Color - Chain connector: Black - Chain connector finish: Black Oxide
