The SRAM PC-1191 chain builds on the fantastic performance of the 1091R to provide the best chain possible for SRAM's Red22 11-speed cassette group. The new SRAM RED 22 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. The HollowPin construction of SRAM's 11 speed chain provides smooth, precise shifting and weight savings without sacrificing strength.
Compatibility of the PC-1191R chain is for SRAM Red 22 & Force 22 Front & Rear derailleurs, Cranksets and cassettes. SRAM uses its familiar Power Link for easy chain installs where there is no worry to get a pin in perfectly straight and at the right depth - something even experienced mechanics can struggle with. Basically just put the Power Link in place with your hands and pull it into position with a little drivetrain tension.
