What makes the SRAM PC-1091R the top 10-speed chain?

The SRAM PC-1091R is SRAM's professional-grade 10-speed chain, built with PowerChain II geometry and SRAM's highest pin-joining strength for maximum reliability under race conditions. Compatible with all SRAM and Shimano 10-speed road and mountain drivetrains, it ships with a PowerLock connecting link for secure closure.

This is the chain that WorldTour mechanics reached for when running 10-speed. The PC-1091R is for riders who demand the absolute best from their drivetrain: precise shifts, exceptional durability, and the confidence that comes from running professional-grade components. If you're building a high-end 10-speed bike and don't want to compromise anywhere, start here.
