Shimano GRX RD-RX815 Di2 Rear Derailleur Info
The Shimano GRX Di2 groupset is Shimano’s premier electronic gravel group for 11-speed shifting. This rear derailleur is compatible with cassettes that have a 42T max low sprocket. The GRX rear derailleur has an integrated chain stabilizer that can be turned on or off depending on the roughness of the terrain. This leads to quieter shifting and less chain slap as your bike vibrates. The RX815 Di2 Rear Derailleur takes some qualities from their mountain bike components. It has a low profile and is compact and stays tight against the frame to avoid damage in the event of a crash. The Shimano GRX RX815 Di2 Rear Derailleur is a smooth and reliable component that will enhance any off-road ride.
SPECIFICATIONS
