Features PowerLock® tool-less connecting link Chrome Hardened Pins Solid Pin rivets ISO 4210 compliant. See Declaration of Conformity for details. Technology POWERLOCK SRAM chain engineers developed PowerLock as a tool free, sure, and consistent way to connect our chains. While PL does not require special tools for install, the especially tight tolerances of 10- and 11-speed drivetrains mandate that each PowerLock is good for a one-time application only. POWERCHAIN II Extremely strong. Incredibly precise. SRAM's PowerChain II increases front and load shifting performance without sacrificing rear shifting precision. The Step2 riveting process increases the Push Pin Power for increased strength and durability.
