SHIMANO RD-R9250 (DURA-ACE) | Shimano's fastest-shifting 12-speed Di2 rear derailleur in history
A split-second shift can decide the race. DURA-ACE has been refined for precisely that.
The "RD-R9250" from the SHIMANO DURA-ACE R9200 series is a 12-speed rear derailleur that forms the core of the wireless Di2 system.
It achieves approximately 58% faster shifting performance compared to the conventional RD-R9150, making it Shimano's fastest rear shifting in history. It responds instantly to attacks, sprints, and sudden changes in gradient during a race, transmitting the rider's intentions directly to the drivetrain.
Furthermore, the wireless unit, charging port, and switch are integrated into a compact body. It supports Bluetooth® LE and ANT communication, allowing for connectivity with E-TUBE PROJECT and cycling computers. This component, which can be called the brain of DURA-ACE, combines high shifting performance with excellent system integration.
