A smooth-shifting experience from an electronically programmed, precise and perfected front derailleur, the Shimano Ultegra R8050 Di2 11-Speed Front Derailleur E-Tube, Double, Braze-On is a strong choice for any rider looking to bring some e-shifting precision into their drive train, or, to rejuvenate their component base in order to keep everything working harmoniously.
Vastly improved performance over mechanical shifters due to electronic front derailleurs' lack of susceptibility to cable stretch, this Ultegra Di2 compatible component uses electronic shifting cables to move a measured amount each and every time, regardless of conditions or environment. With millimetre accurate shifting guaranteed time after time, you can be sure of picking up your chain and tackling that climb without dropping a ring in the process.
