SRAM chain engineers developed PowerLock as a tool free, sure and consistent way to connect their 10 speed chains.
While PowerLock does not require special tools for installation, the especially tight tolerances of 10 Speed drive trains mandated that each PowerLock is good for a one-time application only.
