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.

• Sold individually or in sheets of 4
• No tools necessary to install
• From a long line of tough, light-weight chain engineering from SRAM.
