The SHIMANO GRX DUAL CONTROL shift/brake lever offers light, responsive 12-speed shifting for touring and racing on mixed terrain. The ergonomic shift lever design ensures high comfort with less pressure on the palms and the textured, non-slip brake levers offer excellent control on rough terrain.
The GRX BR-R820 disc brake caliper offers gravel riders a completely new feeling of control thanks to improved modulation and a faster pressure point. And despite the flatter design, the system is quieter and easier to maintain than ever before.
