Weight: 275 g. (116 link)

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 cog set, netting a lighter, smoother, and yet remarkably more durable drive train.
