SRAM PC1071 Hollow Pin Chain 10spFeatures more heavily chamfered outer plates for improved shifting and quieter running. The chrome hardened pin construction provides longer chain life.HollowPin construction: strong and light weightsPowerLock connecting linkTechnology:HollowPin: We employ HollowPin™ construction on all SRAM top of the line PowerChains. HP yields plate retention strength, front and rear shifting efficiency, and low weight benchmarks unreachable in solid pin chain applicationsPowerLock: SRAM chain engineers developed PowerLock as a tool free, sure and consistent way to connect our 10 speed chains. While PL 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 onlySpecifications:Technology Hollow Pin, PowerLock®Compatible Gears 10Model PC 1071Closing Link PowerLockOuter Plate NickelInner Plate GreyPin Treatment Chrome-hardened pinsWeight: 114 links/259gRecommended Group SRAM Force and industry standard 10 speed system½” x 11/128”Powerlink connector includedUPC:710845644696
