Shimano Ultegra Di2 R8050 11sp Front DerailleurRedesigned to be compatible with a wider 11-speed gear range but still retaining the same slick shifting ability, the Ultegra Di2 R8050 is a real game changer. Stiff and efficient enough to change gears cleanly even when you’re pedalling hard out of the saddle, it’s the ideal front derailleur upgrade for your Shimano Ultegra Di2-equipped road bike.Shimano 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.

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.
