Synchro Shift

For the first time in a Dura-Ace groupset, Shimano’s innovative Synchro Shift is now available as a programmable Di2 option; Synchro Shift creates an intuitive experience with synchronised front and rear shifting, which can be custom programmed. With 'full' and 'semi' Synchro Shift available, this intuitive new mode automatically reacts when you shift from one chainring to another. Remove the guesswork as your rear derailleur shifts automatically to minimise the gear step so you can keep riding with a smooth cadence and rhythm.

Di2 E-Tube

The Di2 E-Tube system provides unmatched shift performance, reliability and rider customisation. Along with enhanced Di2 functionality, the 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. Use the Bluetooth technology for seamless access on smartphones and tablets.

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. With this new Di2 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 chain-line. 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 Rear Derailleur Features:

• Maximum Sprocket: 30T
• Minimum Sprocket: 11T
• Maximum Front Difference: 16T
• Total Capacity: 35T
• Ergonomic shifting operation without stress
• Shimano Synchronised shift
• Low profile rear derailleur design
