Super narrow Dura-ace 10-speed HG chain
The asymmetric design of the 10-speed Dura-Ace chain improves shifting precision and smoothness due to different inner and outer plate chamfers and dimensions. While still saving weight without giving up strength, this chain offers higher durability, silent pedaling, and reduced chain drop even under intense pressure.
• Outer plate - Innovative outer plate form: for reducing chain suck.
• Outer and Inner plates - Redesigned outer and inner plates: for improved contact with gear teeth and smoother shifting.
• Hollow pin and perforated plate for weight saving.
