Shimano Ultegra Di2 R8050 11sp Front DerailleurThe Shimano Ultegra Di2 R8050 11-Speed Front Mech has been redesigned for a wider gear pitch without sacrificing shifting performance. With guaranteed quick and smooth shifting - even when under heavy load such as climbing out of the saddle - the step up to this Ultegra Di2 R8050 11-Speed Front Mech is a game changer.Smart Synchronised ShiftingUtilising Shimano's innovative Synchronised Shift, the front derailleur automatically shifts when the rear derailleur is shifted, which means that both derailleurs work together seamlessly. Conveniently, this shifting technology works  the other way around, too; so, the rear derailleur shifts automatically when the front derailleur is shifted. This means you will always have optimal front/rear gear positioning. Di2’s auto-trim feature automatically centres the front derailleur precisely around the chain, which avoids chain rub as you travel across your cassette.Welcome to the New-Age of performance-oriented shifting.Features:New designed pull arm for more direct and easy shiftingImproved clearanceUpgraded to shift under high pedalling torqueSynchronised ShiftWeight: 132gTechnologies:Di2: The power and precision of Di2 is unmatched.
