The 11-speed Shimano Dura-Ace 9000 mechanical groupset is exceptional with every detail engineered to exacting standards for flawless performance. The redesigned shift lever is ergonomically pleasing, delivering precise, smooth shifting with front or rear derailleur. The even-shifting Dura-Ace 11-speed chain is coated with PTFE for 20% more durability, spining quietly and efficiently around a beefy drivetrain. Dual pivot brake calipers, combined with special low-friction cables, have significantly more braking power, while large, hollow-forged aluminum crankarms increase rigidity, boosting power transmitted through the drivetrain. Five cassette arrays accommodate a variety of riding terrain and ability.
