Sram PC1091R HollowPin PowerLock road/MTB Bike Chain

The latest 1091R chain features more heavily tapered outer plates for improved shifting and quieter operation. Other improvements include a new inner plate finish and a hardened chrome pin design for increased chain life.. SRAM's HollowPin™ 10-speed PowerChain™ design delivers smooth, precise shifting and reduced weight without sacrificing strength. Specifications: - Main technological features: HollowPin™, PowerLock® - Compatible transmissions: 10 - Model: PC 1091R - Closing link: PowerLock® Tool-Free Connecting Link - Pin processing: Hardened chrome pins - The weight: 255 grams / 114 links - Rivet type: Hollow pin - Recommended group: SRAM RED® and standard 10-speed systems - Speeds: 10 - Colors: Outer plate: Nickel Silver with Lighting Hole, Inner Plate: nickel silver - Compatibility: SRAM RED®, SRAM Force®, SRAM Rival®, SRAM Apex® and standard 10-speed systems Technology: HollowPin™: We use HollowPin™ construction on all SRAM's top-of-the-line PowerChains. HP provides plate retention strength, forward and reverse shifting efficiency and low weight that is unattainable with solid pin chains. PowerLock®: SRAM chain engineers developed PowerLock as a reliable, consistent way to connect our 10-speed chains without tools.. While the PL requires no special tools for installation, the particularly tight tolerances of 10-speed transmissions dictate that each PowerLock is suitable for one-time use only.
