The SRAM PC-870 is an 8-speed chain built on the PowerChain II platform — a design that improves both front shifting performance and lateral strength without compromising the rear indexing precision that 8-speed systems depend on. Step2 riveting reinforces each link for durability under load, and the PowerLink master link makes installation and removal tool-free.

Highlights

  • PowerChain II platform — improved front and load shifting performance
