With its compact and smooth appearance, the Shimano Dura-Ace Di2 front derailleur delivers quick and smooth front shifting even under high pedalling torque. Plus, it has programmed chain guide trim settings and can be used in full or semi Shimano Synchronised Shift modes to bring you a personalised, top-level shifting experience. Shimano's 9150 groupset brings its Syncro-Shift technology to the road too. Syncro-Shift technology enables the Shimano Dura-Ace Di2 R9150 front derailleur to read the position of your Di2 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.
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.
The Shadow design of the Shimano Dura-Ace Di2 rear derailleur means it sits under the chainstay and cassette to give a slimmer profile, which not only improves aerodynamics but offers faster wheel changes and helps to prevent damage in a crash. It also offers faster and more precise shifting than ever before. Shimano's 9150 groupset brings its Syncro-Shift technology to the road too. Syncro-Shift technology enables the Di2 front derailleur to read the position of your Shimano Dura-Ace R9150 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.
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.
This Shimano road brake cable set features die-extruded PTFE coated inner wires that leave a smooth surface for low friction in use, while its stainless steel build provides smooth shifting and higher corrosion resistance.
The clad steel / alloy / steel rotor construction of the Shimano ice tech rotor allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 degrees C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 degrees C, this provides great improvements in performance all around. Freeza rotors allow the alloy core to extend out from the braking surface as fins to the centrelock mount adapter to provide added cooling. Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion. The Shimano dura ace disc rotors are durable lightweight and rigid, using the proven centrelock system giving increased strength and security with an easy set-up. Plus, the precision cut and drilled braking surface improve pad clearing in muddy conditions while aiding cooling under high load. Finally, the large alloy spider is highly rigid and lightweight support for the rotor surface.
Ready to bring you efficient braking control without changing your hand or body position, this Shimano aero brake lever seamlessly combines with Shimano brake calipers for strong stopping power and fine speed control. This means you can confidently carry more speed into the corners for maintaining your momentum, which is an essential skill during races.
These metal (sintered) Shimano XTR brake pads are perfect for use in wet or dry conditions and will perform equally as well in both. Always use Shimano Disc Brake pads to ensure top brake performance and to maintain the safety of your Shimano brake system. Compatible with the following Shimano brakes: BR-M9000, BR-M9020, BR-M8000, BR-M987, BR-M985, BR-M785, BR-M675, BR-M615, BR-RS785
This Shimano Dura-Ace cassette is manufactured from a lightweight alloy and carbon fibre reinforced polymer 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 on the Shimano Dura-Ace 11 speed cassette thanks to the Hyperglide (HG) EV sprockets that have a computer designed tooth configuration with contoured shift gates.
The BM-DN100 Battery Mount is ideal for use on frames that are running Shimano Di2 components externally. This mount is specifically designed for the new Bluetooth SM-BTR1 battery, which gives earlier versions of Di2 the feature of being able to change your shifting preferences wirelessly.
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.

Providing consistent performance alongside the optimal balance of durability and lightweight, this tried and trusted mountain bike (MTB) component won't let you down when you're attacking the trails. The crank arms on the Shimano XT boost crankset feature HollowTech II technology for an unrivalled strength-to-weight ratio. Please Note: This is the left and right hand crank arms only, the chainring and bottom bracket are both sold separately. Technologies: Hollowtech II: Providing the best balance of stiffness, strength, weight and rotating performance, the concept of Hollowtech II technology is focused on producing a superior crankset that will maximise a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more.
