Shimano's GRX groupsets have always been designed to bring smooth shifting, reliable braking, and comfort to gravel riding. The Shimano GRX ST-RX610 hydraulic brake/shift levers use trickle-down technology from the original GRX 800 series to bring all the GRX performance qualities to a more budget-friendly tier. Designed for performance and comfort on rough surfaces, you'll find textured hoods for a secure grip as well as an anti-slip coating on the brake levers for added confidence in wet or muddy conditions. Updated with 12-speeds, you'll get more options, more gears, and more opportunities to ride the way you want to.
