Complete your dream ride with the Dura-Ace Di2 R9150 groupset. Combining classic design and engineering with cutting-edge technology, this build kit is made to world standard, setting new benchmarks in what the road, TT and CX worlds can look forward to experiencing. Wired communication between shifters and the rear derailleur enables precision gear changes for an overall cleaner and more efficient finish to your bike. Welcome to the new frontier of cycling, you’re going to love it.

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.

The Shimano Dura-Ace 9100 brakes have been developed to offer greater clearance for tyres up to 28c while maintaining the aerodynamic advantage of Shimano's previous editions. Other improvements are that these calipers are now up to 43% stiffer than previous Dura-Ace brakes and offer a linear braking curve for improved feel and function. To improve aerodynamics, the quick release arm tucks in towards the main body when closed.
