Shimano Ultegra CN-6701 10 Speed Chain

ULTERGA now features an asymmetrical (directional) chain. Shifting precision and smoothness has been significantly improved through the use of different inner and outer plate chamfers and dimensions to accommodate the different shifting requirements of moving the chain inward and outward on the drivetrain.

Features:

• Redesigned inner and outer plates
• New shaped outer plate
• New shaped inner plate for smoother rear shifting
• Enhanced press-in construction for stable shifting
• Chain Type Super Narrow HG for 10-speed
