Shimano GRX ST-RX610-L brake lever

Shimano GRX ST-RX610-L brake lever

The Shimano GRX ST-RX610 left lever is designed for a gravel bike with a single-chainring 1x12-speed drivetrain. In this configuration it serves as a hydraulic brake lever without shifting, because the 1x drivetrain uses only the right shift lever for the rear derailleur.

The GRX series ergonomics are optimised for riding on gravel and off-road, with a secure grip and stable control when braking, even on uneven surfaces.

Features and benefits:

• Hydraulic brake lever for 1x12-speed drivetrains

• Left lever without shifting

• Ergonomic shape for gravel bikes

• Reliable and consistent braking performance

• Suitable for road and off-road riding

• Compatible with Shimano GRX calipers
