With Shimano's groundbreaking new Dura-Ace 11-speed drivetrain comes the chain to match. The CN-9000 has been designed from the ground-up, combining smooth shifting performance with outstanding durability and an impressively low weight.
Unlike last year's Dura-Ace chain, the CN-9000 features a symmetrical design, making it easier to install than its unidirectional predecessor. The thinner profile matches the new 11-speed cassette and chainring teeth while reducing the overall weight. Hollow pins further the weight reduction and a friction reducing PTFE coating is borrowed from Shimano's Dura-Ace cable systems for silkly smooth shifting performance, front and rear.
The Dura-Ace CN-9000 chain includes Shimano's 11-speed installation pin. Compatible with the Shimano TL-CN28 chain tool (sold separately). Claimed weight: 243g.
