Shimano Dura Ace Di2 R9150 11 Speed STI Shifters
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-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.
Shimano Dura Ace Di2 R9150 Front Derailleur
The Dura-Ace 9150 front derailleur delivers unmatched shift quality, for quick and smooth performance even under high pedalling torque.
Shimano’s Synchro Shift customisable programming, allows Dura-Ace Di2 to offer top level shifting.
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.
Shimano Dura Ace Di2 R9150 Rear Derailleur
The Dura-Ace R9150 rear derailleur takes Shadow technology from Shimano’s MTB 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 improves aerodynamics but helps prevent damage in a crash.
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.
Shimano's 9150 groupset brings their Syncro-Shift technology to the road too. Syncro-Shift technology enables the front derailleur to read the position of the rear derailleur and will automatically operate the front shift to position the gears in the most efficient gear and best chain line so you'll never have to worry about front shifting and correction shifts again.
Shimano Dura Ace R9100 Cranckset
The Shimano Dura-Ace R9100 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.
Shimano Dura Ace R9100 Bottom Bracket
Official Shimano Bottom Bracket for use with the R9100 and R9150 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 HG901 11 Speed Chain
Super narrow lightweight 11-speed HG-EV symmetrical design chain for smooth shifts and maximum durability.
This is the undisputed king of chains! Decades of Japanese engineering and refinement have brought you the most technologically-advanced chain Shimano has ever delivered. Designed specifically for today's 11-speed systems, this Dura-Ace / XTR chain uses an asymmetric layout for better performance and better shifting performance. The chain also runs very quietly, because it has been coated with SIL-TEC, a new Shimano fluorine-based metallurgic surface treatment which decreases friction and increases chain life. Not only that, but SIL-TEC holds onto your lube better and longer, leading again to better chain performance. Finally, Shimano has added hollow pins to shed that extra weight. When it comes down to chains, details matter. Why not put the best on your bike? It deserves it.
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.
