The concept behind the new Shimano Dura Ace R9100 groupset was to examine and improve every component to optimise the input and maximise the output.
Each component has been re-engineered to ensure maximum stiffness, performance and minimum weight.

Shimano Dura Ace R9100 STI 11 Speed Shifter Set
Precision-engineered Dura-Ace STI lever for the ultimate in powerful braking and effortless 11-speed shifting, making it the global choice for road racing's elite riders.
Dura-Ace R9100 STI are lightweight thanks to carbon fibre lever blades, carbon composite bracket body, and a titanium clamp band / fixing bolt.
Shift cables routed under the bar tape using Polymer coated inner wires make for a smooth shift action, providing faster, lighter shifting. Vivid Index shifting with short stroke to the release levers gives a quick and accurate shift.
Gear shift cables can either be routed round the front or rear of the handlebar to suit all rider preferences. Ergonomic shift arc follows natural hand movement with inward shift stroke distance reduced for rapid and precise gear changes.
Small volume ergonomically designed smooth lever hoods for added comfort. Brake lever pivots have been positioned to increase power and improve ergonomics when riding on the hoods. Finely tuneable reach adjusters for the levers enable custom fitment for all hands.
Shimano Dura Ace R9100 Front Derailleur
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.
Shimano Dura Ace R9100 Rear Deraillleur
The Dura-Ace R9100 rear derailleur takes Shadow technology from Shimano’s MTB range and introduces it to the road.
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 R9100 derailleur only comes in one length and will work with cassette sprockets up to 30T. This means that the R9100 offers a greater rider tuned ratio than previous editions.
The shadow design places the rear derailleur under the chainstay and cassette to give a slimmer profile, which not only improves aerodynamics but helps prevent damage in a crash.
Shimano Dura Ace R9100 Cranckset
The Shimano Dura-Ace R9100 Crankset 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 Compact version offered here features a 50.34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains.
Shimano Dura Ace R9100 Bottom Bracket
Official Shimano Bottom Bracket for use with the 9100 and 9150 Dura Ace drivetrains.
The Shimano Dura-Ace R9100 Bottom Bracket features smaller lightweight bearings and an advanced seal construction for smoother rotation and increased durability. It is designed to work in combination with the Dura-Ace R9100 crankset to offer optimum stiffness and a smoother pedal stroke.
Shimano Dura Ace R9100 11 Speed Cassette
Shimano have retained the traditional close cassette ratios from previous editions of Dura-Ace, but with the new R9100 groupset they have also introduced a wide range 11-30T cassette.
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.
Shimano Dura Ace 9000 XTR M9000 HG900 11 Speed Chain
The Shimano Dura Ace XTR HG900 11 Speed Chain. Super narrow lightweight 11-speed HG-EV symmetrical design chain for smooth shifts and maximum durability.
HG technology has chamfered inner plates to optimise shifting performance on HG sprockets. Good durability is assured through a chromising treatment on link pins, and the heat treatment of rollers, pins, and plates.
Shimano Dura Ace R9100 Road Brakes
49mm drop rim brakes for use with the R9100 drivetrain.
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 quick release arm now tucks in toward the main body when closed for improved aerodynamics.
