Comfort For The Long Rides
GRX's redesigned ST-RX610 Levers feature textured hoods and an anti-slip brake lever coating that bolsters control on rugged terrain. Shimano have updated its 600-series cranks and shift levers for 1x12 and 2x12 setups that utilize trickle-down technology from the original 800 series GRX component line. Adding 12-speed shifting without any additional lever bulk, the RX610 series shifters are designed for all-day comfort when using flared drop bars, a gravel cycling staple. By reducing pressure points and increasing surface area, your hands will feel less fatigued, and you'll be better in control as you test your limits.
The new GRX shift/brake levers offer light and responsive mechanical 12-speed shifting. While the left lever of the UNDROPPABLE 2x12 GRX group delivers Shimano's unrivaled smooth front shifting, the new 1x12 groups carry over functions for the left lever first introduced with the original GRX: a brake lever-only model and a dropper-specific option that seamlessly integrates braking and dropper post actuation.

Rooted in simplicity, reliability, and adventure, the new 12-speed GRX lineup delivers more gearing options along with unrivaled ergonomics so riders get the most out each unpaved adventure, wherever that might be.
