Shimano GRX rear derailleur
The Shimano GRX RD-RX815 Di2 rear derailleur is specially designed to provide optimal performance on gravel terrain. With its integrated chain stabilization mechanism, it ensures quieter and more precise speed changes, even on rough terrain. This stabilizer is adjustable and can be activated or deactivated according to the conditions, allowing the tension of the chain to be adjusted according to the terrain, whether on a smooth road or a more difficult path.
This derailleur is compatible with ATV cassettes with a maximum sprocket of 42 teeth, making it ideal for transmission configurations offering a wide range of speeds. Its clutch specially designed for the gravel stabilizes the chain to avoid jumps and taps, thus ensuring better safety on the rugged trails. The total capacity of the derailleur is 38 teeth, allowing a smooth and reliable change of speed, even under difficult conditions.
With a light weight of only 287 g, this Di2 model is also compatible with Shimano's current Dual Control levers for road. It can handle a maximum front difference of 17 teeth, with a small sprocket of up to 34 teeth. These features make it an essential part for engravers and cyclists on various terrains, where performance and reliability are crucial.

- Activation/deactivation of the stabilization switch depending on the terrain
- Compatible with the current DUAL CONTROL LEVER route
