The cassette is manufactured from a lightweight alloy and carbon fibre spider that houses 6 alloy sprockets and 5 titanium sprockets. The largest sprockets are manufactured from titanium to keep the weight low. The sprockets are also extensively cut away and drilled to further reduce weight without reducing rigidity. The very best and quickest shifts are optimised thanks to the Hyperglide EV sprockets that have a computer designed tooth configuration with contoured shift gates. All cassettes in the range will be compatible with the one rear derailleur so you can easily swap your cassettes out based on terrain.

E-Tube compatibility means that the function of the shift paddles can be customised to suit the rider. The shift paddles now feature a more defined "click" and have been extended in length for more confident and comfortable shifting. The 9150 shifters now include Synchro-shif technology that automatically moves the rear derailleur when the front ring is changed or moves the front chainring with the rear shifts to optimise chainline and drivetrain efficiency.

The HollowTech II 12-speed Dura-Ace chainset offers the optimum balance of light weight and rigidity, making it the global choice for road racing's elite ridersHollow outer chainring, giving vast improvements in rigidity and increased weight savings,The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load,These industry leading HollowTech II 4 arm cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength,The teeth have been developed to work only in conjunction with the 12-speed chains for improved contact providing more efficiency and improved power transfer,There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines,HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency,Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability.
Shimano Dura-Ace R9100 11 Speed Road Double ChainsetThe Shimano Dura-Ace R9100 11 Speed Road Double Chainset boasts Shimano's well-known 4-arm hollow spider that is constructed from hollow-forged aluminium. This chainset has been completely redesigned to ensure it boasts the best combination of lightweight and rigid construction. The chainset has been adapted by Shimano to work with disc brake road bikes that have a 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. Although the crank arms and spider arms are bigger, this increases overall stiffness, and the chainset has dropped 7g of weight since its previous edition.The Double version offered here comes in numerous gear combinations to best suit each individual riders needs.Please note: A bottom bracket is NOT included.Features:Enhanced design saves 7g while maintaining rigidityIconic 4-arm construction maintains high rigidity and reduces weightOptimised crank arm design strengthens key stress zonesNew chainring tooth profile is adapted for race bike specific disc brake systemsAccommodates shorter chainstays (410mm) with 135mm OLD rear spacingHollowglide chainring construction maintains smooth shifting whilst reducing weight and increasing stiffnessWeight: 621g (53.39T)A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
