The SRAM PC-971 is a 9-speed chain built on SRAM's PowerChain II platform — a design that improves front shifting performance and load capacity without compromising the precise rear indexing 9-speed drivetrains depend on. Step2 riveting adds lateral strength so the chain resists the side loads that come with 9-speed gear ratios.

Highlights

• 9-speed chain compatible with SRAM and Shimano-standard 9-speed drivetrains
• PowerChain II design — improved front and rear shifting performance
• Step2 riveting process for increased lateral strength and durability
• Includes PowerLink master link for tool-free connection and disconnection

PowerChain II

SRAM's PowerChain II uses a revised plate shape and rivet design to handle the lateral flex loads imposed during front shifting — moving from small to large chainring and back — while maintaining the tight lateral tolerances that keep rear indexing accurate. The Step2 riveting reinforces each link at the rivet point for improved resistance to chain stretch.

Fit and compatibility

9-speed chain. Compatible with SRAM and Shimano 9-speed road and MTB drivetrains. Confirm speed compatibility before ordering. Replace at 0.75% chain wear to protect cassette and chainring longevity.
