Shimano CN-7900 10 Speed Dura Ace Bicycle 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.

● Redesigned outer plate | Reduces chain suck
● Redesigned asymmetric outer and inner plates | Better contact with gear teeth and smoother shifting, high efficiency pedaling
● Hollow pin and perforated plates | Lightweight & strong
● Weight: 252g (114 links)
