SHIMANO GRX RD-RX810 REAR DERAILLEUR2X11 ACTIONGravel riding is becoming increasingly popular, which means that there is a rise in gravel-specific components that perform better offroad. The Shimano GRX RD-RX810 Rear Derailleur is designed for 2x11 drivetrain setups. It has an adjustable chain stabilizer that prevents chain slapping and drops that can be toggled on and off to match the terrain. The gravel-tuned clutch tension lets the derailleur perform better over rougher terrain. It is silent and has uninterrupted rear shifting on rough terrain and smooth and reliable mixed surface shifting. It is compatible with current road dual control lever shifters.FeaturesSilent and uninterrupted rear shifting on rough terrainAdjustable chain stabilizer prevents chain slapping and dropsCompatible with current road dual control lever shiftersSpecificationsLow Sprocket Max34TLow Sprocket Min30TTop Sprocket Max11TTop Sprocket Min11TTotal Capacity42T | Shimano GRX RD-RX810 Rear Derailleur 2x11 Speed
