Shimano GRX ST-RX610-R 12-speed right-hand Gravel bike handlebar grip with brake caliper

The Shimano GRX ST-RX610-R 12-speed right-hand shifter has been specially designed for demanding gravel riding, where control and reliability are essential. Thanks to its ergonomics designed for mixed terrain, it ensures a secure and comfortable grip, even on the most unstable surfaces. Its lever features a non-slip coating offering optimal control during sudden braking or on technical descents.

The J-Kit system simplifies installation and makes connecting the hose easier, making maintenance particularly straightforward. Featuring Ice Technologies, heat dissipation is improved to ensure consistent and quiet braking in all conditions.

Compatible with GRX Flat Mount calipers, it offers precise and controlled braking performance, ideal for long gravel rides. Its reliable construction and intuitive design ensure high-performance and durable use, whether you’re riding on roads, undulating trails or rough tracks.
