Designed specifically to meet the demands of all 11Spd drivetrain systems, this chain is compatible with both SRAM road and mountain bike 11Spd drivetrains. The PC-1170 has been designed using features such as a more heavily chamfered outer plate for improved shifting and quieter running. The chrome hardened pin construction provides longer chain life too, providing a lightweight chain that is built to be tough and allow for efficient shifting that you can count on every time.
