The Shimano GRX ST-RX400 is a 10-speed gravel inspired dual control shift/brake lever with the same intuitive and quick shifting operation as top tier systems. The tooled reach adjust allows for the lever to be adjusted to fit multiple hand placements and rider hand sizes.
The ergonomic design offers a more drastic slope and a textured brake lever, increasing comfort and control on trails and mixed-terrain.
