The Shimano Dura-Ace FD-R9250 Di2 12-Speed Front Derailleur is smaller (33% less frontal area) and lighter than previous models (96 grams). It also connects to the battery via an E-Tube wire.
The new FD-R9250 Di2 12-Speed Front Derailleur was designed to accommodate the new 54-40T Dura-Ace FC-R9200 Hollowtech II 2x12-Speed Crankset option.
Tipping the scales under 100 grams, the new design shifts 45% quicker than Shimano's FD-R9150, already the fastest on the market.
A new Shimano E-TUBE App (version 4.0.0) offers intuitive operations for personalizing the Dura-Ace R9200 drivetrain. Offering a suite of customizable, riders can choose between different shift speeds, customize shift button mapping (what buttons perform which functions), program different automatic shift modes like Synchro and Semi-Synchro shifts, fine-tune shifting, and connect with third party bike computers.
