Each component has been re-engineered to ensure maximum stiffness, performance and minimum weight.

First introduced in XTR Di2 M9050, Shimano’s innovative Synchro Shift is now available with Dura-Ace R9150. Available as a programmable Di2 option, Synchro Shift creates an intuitive experience on the bike through Synchronised front and rear shifting that can be custom programmed by riders.

In addition to traditional “Full” Synchro Shift, riders can optionally select “Semi” Synchro Shift. This intuitive new mode automatically reacts when the rider shifts from one chainring to another, automatically shifting the rear derailleur to minimise the gear step, thus preserving the rider’s rhythm.

Di2’s E-Tube system provides unmatched shift performance, reliability and rider customisation. Along with enhanced Di2 functionality, expanded E-Tube wire options and junction boxes as well as the new EW-WU111 Wireless Unit, deliver improved wiring configurations and wireless connectivity to Shimano’s E-Tube Project.

Front and rear Di2 derailleurs are connected via Shimano’s small EW-WU111 wireless unit allowing for an ANT Private connection between Dura-Ace R9100 and third party devices. These components can be connected to Shimano´s E-TUBE software, which supports the programmable aspects of the Di2 electronic gear shifting system. Additionally, via Bluetooth technology, this is also accessible on smart phones and tablets.

Dura-Ace R9100 Crankset:
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.

Dura-Ace Di2 R9150 2x11 STI Shifter Set:
The Dura-Ace Di2 9150 shifters feature an ideal ergonomic shape that is comfortable in the hand and have been updated to be more precise and more adaptable than previous editions. The shift paddles now feature a more defined "click" and have been extended in length for more confident and comfortable shifting.

E-Tube compatibility means that the function of the shift paddles can be customised to suit the rider.

The 9150 shifters now include Synchro-shift 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.

 

Dura-Ace Di2 R9150 Rear Derailleur:
The Dura-Ace Di2 R9150 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 new derailleur comes in only one cage size that will work with cassette sprockets up to 30T. This means that Dura Ace offers a greater rider tuned ratio than previous models.

With this new 9150 groupset Shimano brings Synchro-Shift to the road too. This technology allows you to shift to higher or lower gears with your right hand shifter and both front and rear derailleurs will operate to optimise chainline. It will also automatically shift the rear mech when you change from the large ring to the inner ring to maintain smoothness.

Dura-Ace Di2 R9150 Braze On Front Mech:
The Dura-Ace 9150 front derailleur delivers unmatched shift quality, for quick and smooth performance even under high pedalling torque. Combined with Shimano’s Synchro Shift customisable programming, Dura-Ace Di2 delivers a level of intuitive shift performance never before seen.

Dura-Ace R9100 Road Brake Caliper Set:
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.

Dura-Ace R9100 Cassette:
Shimano have retained the traditional close ratio cassettes from previous editions of Dura-Ace, but with the new R9100 groupset they have introduced a wide range 11-30T cassette. All cassettes in the range will be compatible with the one rear derailleur so you can easily swap your cassettes out based on terrain.

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.

Weight: 175g (11-25T), 193g (11-28T), 211g (11-30T), 189g (12-25T), 205g (12-28T)

Dura Ace 11-speed Chain CN-9000 114 Links:
The new symmetrical 11-speed Dura-Ace chain uses hollow pins for low weight, PTFE coating for smooth shifts and offers increased durability.
