Shimano GRX RX820/RX825 Groupset - Di2 | 1x12-speed

GRX Di2 – Gravel Goes Wireless.

With components specifically designed for 1x12-speed drivetrain systems, the GRX series is celebrating its debut in the completely wireless shifting segment. The focus is on the RD-RX827 rear derailleur, which is based on the wireless models of the XTR M9250 series. The 1-speed concept is complemented by the BL-RX825 brake lever and the WH-RX810 wheels. Equipped like this, gravel athletes can experience what ultimate reliability means on any terrain – whether racing, back-roading on remote trails or on your next all-day adventure.
