FEATURE - Outer plate design has been developed to reduce the chance of chain suck - Sil-Tec surface treatment technology (PTFE plating) on inner and outer links and rollers that is smooth - - running and increases durability - Zinc-Alloy plated inner and outer links - Hollow pin for added weight saving - The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity and near silent running - 5.62mm chain width, optimised for 11-speed Super Narrow HG-EV drivetrains
