Shimano Dura-Ace Di2 9250 Rear Derailleur Info
The Shimano Dura-Ace Di2 9250 Rear Derailleur is the shifting benchmark for 12-speed electronic road cycling — the component around which the rest of a performance drivetrain is built. Shimano designed it to shift 58 percent faster than its predecessor, a difference you feel most in rapid-fire cadence changes and high-pressure race moments where hesitation isn't an option.
A single cage length handles up to a 34-tooth low sprocket, giving you a wider gear range without managing multiple cage options. Wireless connectivity is integrated directly into the derailleur alongside the system charging port, and an onboard LED indicator keeps you informed of battery status, pairing state, and adjustment mode — so you know exactly where the system stands before and during a ride.
