This Shimano Dura Ace FC-R9100 HOLLOWTECH II Crankset (2x11-speed) is wider than its predecessor but is still very lightweight by utilising the Hollowtech II technology. The highly rigid hollow structure cuts down on weight but still maintains strength resulting in better power transfer and more precise front shifting.
The Shimano Dura-Ace CS-R9100 11-28T 11sp Cassette offers Rider Tuned gearing and improved drivetrain precision through reliable and easy up or down-shifting.
Shimano Dura-Ace Di2 Hydraulic Disc Brake option for road. The R9170 brake lever integrates the hydraulics in the shifter and the flat mount brake calliper is as lightweight and aerodynamic as you would expect from Dura-Ace.
Note: Disc rotors not inlcuded
