Rear Derailleur Shimano GRX RD-RX810 11-speed

The Shimano GRX RD-RX810 is an 11-speed rear derailleur designed specifically for gravel riding, featuring an integrated chain stabilizer. It reduces chain vibration and slap, delivering quieter and more precise shifting on rough terrain.

The adjustable stabilizer with ON/OFF switch allows you to fine-tune chain tension according to riding conditions – lower resistance on smooth roads and maximum stability on gravel and trails. The gravel-tuned clutch tension is optimized for mixed-surface performance.

The RD-RX810 is compatible with 11-speed road DUAL CONTROL LEVER shifters and supports up to a 34T largest sprocket. With 40T total capacity and up to 17T front difference, it provides a wide and versatile gear range for both speed and steep climbs.
