The Dura Ace 7901 10 Speed Chain was forged with an asymmetric shape with redesigned inner and outer plates that rid of chain suck and improve contact with the cassette sprockets for a smoother, noiseless shifting under the most extreme of loads.
Crafted with hollow pins and a perforated inner plate, the weight on the Dura Ace 7901 10 Speed Chain drops nearly 30 grams compared to its predecessors while also enhancing durability. It also features an enhanced press-in construction that offers stable shifting action and works on all 10 speed Shimano drivetrains.
