The Shimano GRX ST-RX825 Di2 Shifter brings comfortable and reliable wireless shifting to our gravel riding experience. With updated ergonomics designed specifically for flared handlebars, the alignment between the hoods and bars is smoother than ever, creating a larger surface area that eliminates pressure points for added comfort. They also feature raised hoods with a ribbed surface and anti-slip brake levers to increase control on rough terrain and in bad weather, while the third Di2 button on the inner hood offers added customization.
