Where The Magic Happens
The Shimano RX825 Rear Derailleur features Shimano's pioneering Shadow RD+ technology. With its convenient on/off switch, Shadow RD+ makes removing the rear wheel easy when turned off. When on, the drivetrain is under additional tension that makes for a quieter ride and more precise shifting.
Like on Shimano's road 12-speed Di2 systems, the rear derailleur is also the communication hub of the drivetrain, communicating wirelessly with the shift levers, compatible cycle computers, and E-TUBE PROJECT Cyclist via a smartphone. It also houses the system's charge port and the multi-function button which allows riders to easily check battery level, pair via Bluetooth, and enter adjustment mode for both derailleurs.
Using Shimano's E-TUBE PROJECT Cyclist application, riders can choose between different gear shift intervals for multi-shift, customize shift button assignment (what buttons perform which functions), program different automatic shift modes like Synchronized and Semi-Synchronized shifts, and fine-tune shifting.
