Shimano 2014 Dura Ace 10 Speed Bicycle Chain CN 7801 ICN7801116I

The new 10 speed Dura Ace chain is lighter by an astonishing 24g, yet maintains the same durability as the 9 speed predecessor. The chain also adds a new fluid smooth feel to the performance of the overall system. The rollers are the same width as 9 speed, insuring the important strength and durability. Weight reduction and the narrower 10 speed profile were achieved by minimizing the contour of the side plates. The super flush surface of the new plates glides more smoothly across the entire cogset, netting a lighter, smoother, and yet remarkably more durable drive train.
