Shimano Dura-Ace R9150 Di2 11 Speed Groupset/Upgrade Kit
The concept behind the new Shimano Dura-Ace R9150 groupset was to examine and improve every component to optimise the input and maximise the output. Or to put it another way, to minimise the energy loss between the effort a rider puts in and the performance he or she achieves.
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, optional EW-WU111 Wireless Unit, deliver improved wiring configurations and wireless connectivity to Shimano’s E-Tube Project.
