Engineering at it’s Peak
With their reputation for precision shifting, high dependability and buttery smooth performance, Shimano have taken to the new Dura-Ace 9100 line-up and delivered the goods.
With class-leading Dura-Ace 9100, you get to share in Shimano’s best. Below details some of the key upgrades to the Dura-Ace 9100 componentry, which deliver improved ergonomics and aerodynamics.
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.
Using a carbon fibre and alloy spider and five titanium sprockets, the DURA-ACE R9100 cassette provides accurate shifting and light weight to the most discerning road cyclists on the planet.
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.
The Dura-Ace 9100 shifters have received an overhaul over previous editions with the aim of improving ergonomics and shifting efficiency. They now feature a re-designed brake hood for a comfortable grip - convenient for smaller hands. These shifters also offer up to 14mm of reach adjustment. The front shifter has a lighter lever swing for a more linear stroke and the rear shifter has an improved shorter lever stroke allowing quicker shifts with less effort.
This Shimano Dura-Ace 9100 11-Speed Rear Derailleur is at the pinnacle of mechanical shifting performance with a lightweight carbon cage, carbon fibre pulley plates and sealed pulley bearings for a dramatic reduction in friction resulting in shifting smoothness and responsiveness.
