Product Description

Shimano Dura-Ace 9100 11-Speed Mechanical Groupse

Introducing the Shimano Dura-Ace 9100 11-Speed Groupset - the latest top-of-the-range mechanical road groupset from one of the leaders in bicycle componentry.

The Shimano Dura-Ace 9100 Double 11-Speed STI Levers offer the pinnacle of mechanical shifting thanks to an ultra-light and durable carbon fibre composite construction and cutting edge technology in the form of Vivid Index shifting.

The levers come in at just 365-grams thanks to the integration of carbon fibre lever blades, carbon composite bracket bodies and a titanium clamp band. Shift cabling can be routed either round the front or rear of the handlebars depending on your preference. The shifting cables are Polymer coated to ensure a smooth shift action for faster and more responsive shifting.

The Shimano Dura-Ace 9100 Brake Calipers are the pinnacle when it comes to braking predictability and balance. The redesigned alloy arm construction offers superior stiffness and stopping power with a more predictable linear braking curve. The smaller gap between each arm helps to reduce drag and add stability while the sleek design looks superb as part of any bike setup. The caliper can fit tyres up to 28mm in width.

Shimano's top-of-the-range chainset has got more than just a facelift with the Shimano Dura-Ace 9100 Double Chainset. Designed to optimise power transfer, this crankset is seven grams lighter than the previous Dura-Ace iteration. This reduction of weight does not come at the expense of stiffness as it still boasts optimal stiffness and efficiency with a newly designed crank arm. The four arm construction boasts strength and aerodynamic efficiency.

HollowGlide technology on the chainrings improve shifting crispness and smoothness with individually designed tooth profiles. The tooth profile also helps to fit a wider gear pitch.

The pro-level Dura Ace 9100 11-Speed Cassette provides ultra-lightweight shifting and Shimano's rider tuned gearing for smooth shifting no matter what ratio you are running. The spider is constructed from a carbon fibre reinforced polymer (CFRP) and alloy combination, making it super-light, stiff and durable. Five titanium sprockets on this 11-speed cassette ensure longevity while keeping the weight low.

Mechanical shifting does not come better than it does with the Shimano Dura-Ace 9100 11-Speed Rear Derailleur SS. Ultra-smooth, durable and light thanks to a carbon construction, this derailleur redefines mechanical shifting performance.

Shimano has done a fantastic job of integrating carbon fibre parts into the derailleur's construction to both boost weight and enhance performance. The carbon cage combines with carbon fibre inner and outer pulley plates to enhance rigidity and strength.

Shimano has not cut any corners and have utilised pulleys constructed from DuPont's Zytel material for greater longevity and less chain noise. This means the SS design is compatible with ratios up to 30T; adding extra versatility for mountainous rides.

The Dura-Ace 9100 11-Speed Front Derailleur provides riders with smooth and crisp shifting with an intuitive ergonomic action. The derailleur is easy to setup and the integrated cable tension adjuster allows you to adjust alignment on the go. The derailleur offers compatibility with multiple cable routing options and the maximum gear range of 46-55T means that a wide range of gearing options is accommodated, including oval chain rings.
