The newest 1091 chain features more heavily chamfered outer plates for improved shifting and quieter running. Other advancements include a new inner plate finish plus chrome hardened pin construction, both for longer chain life.

Technology: 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 applications PowerLock: SRAM chain engineers developed PowerLock as a tool free, sure and consistent way to connect 10 speed chains.
