Evolved Di2 Technology & Precision Shifting

The Dura-Ace RD-R9250 rear derailleur features a Shadow design and comes with integrated D-FLY connectivity so you can pair with Bluetooth & ANT+ compatible devices. It connects to the battery via an E-Tube wire.

Dura-Ace R9200's new Di2 platform showcases Shimano's most advanced drivetrain technology and shifting performance to date. Dura-Ace delivers 58% faster rear shifting and 45% faster front shifting compared to the current wired R9100 Di2 system. Shimano's wireless Di2 processing technology, developed in-house by Shimano, increases transmission speed and performance, offering reliable, fast shifts every single time. Further Di2 refinements include a charging port and D-FLY wireless connectivity integrated into the rear derailleur.

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.
