Shimano GRX RX610/RX400 Shift Lever and Brake Set Info

The Shimano GRX RX610/RX400 Shift Lever and Brake Set brings 12-speed gravel shifting and hydraulic disc braking together in a pairing built for mixed-terrain riding. The RX610 lever handles shifting duties with an ergonomic profile designed for comfortable hand placement across long hours in the saddle — reach adjust and an anti-slip texture let you dial in the fit regardless of conditions. It's also at home on flared drop bars, which makes it a natural choice for riders who prioritize control on rough descents and loose surfaces.

Braking is handled by the RX400 flat mount hydraulic disc caliper, a two-piston unit that delivers consistent stopping power with good heat dissipation — useful when loaded gravel descents are on the agenda. The hydraulic system keeps lever feel predictable whether you're on pavement, hardpack, or something muddier. Sold as individual front-left and rear-right units, so you can replace or upgrade one end without buying more than you need.
