This Shimano - Dura-Ace R9100 11 Speed Groupset is no longer available although you may find similar or newer versions below:
Each component has been re-engineered to ensure maximum stiffness, performance and minimum weight.
The Shimano Dura-Ace R9100 Compact Chainset has been completely re-designed to offer the very best combination of light weight and stiffness. It features Shimano's iconic 4 arm hollow spider that is made from hollow-forged aluminium. Although the crank arms and spider arms are noticeably bigger, which increases stiffness, the overall weight has dropped by 7g over the previous edition of Dura Ace. The crankset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing.
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 that is more comfortable to grip, especially for those with smaller hands. The shifters also offer up to 14mm of reach adjustment. The rear shifter features an improved lever stroke that is shorter than previous editions. This allows for quicker shifts and requires less effort from the rider. The front shifter features a lighter lever swing for a more linear stroke.
The Dura-Ace R9100 rear derailleur takes the Shadow technology from its mountain bike range and introduces it to the road. The shadow design places the rear derailleur under the chainstay and cassette to give a slimmer profile, which not only helps with aerodynamics but also offers extra protection in crashes. The Shadow design offers faster wheel changes thanks to the fact that it moves the derailleur out of the way of the dropouts. It also offers faster and more precise shifting than ever before.
The Dura-Ace R9100 front mech has been redesigned to be smaller, more efficient and provide faster and crisper shifting. The internal toggle mechanism provides greater clearance for larger tyres and it now features a built in cable tension adjustment bolt meaning there is no need for inline barrel adjusters.
The Dura-Ace 9100 brakes have been developed to offer greater tyre clearance for up to 28c tyres while still maintaining the aerodynamic advantage of previous editions. They are now also up to 43% stiffer than previous Dura-Ace brake calipers and offer a linear braking curve for improved feel and function.
The cassette is manufactured from a lightweight alloy and carbon fibre spider that houses alloy sprockets. The 5 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.
The new symmetrical 11-speed Dura-Ace chain uses hollow pins for a light weight, PTFE coating for smooth shifts and offers increased durability.
