The Shimano RX825 Rear Derailleur features Shimano's pioneering Shadow RD technology. With its convenient onoff switch Shadow RD makes removing the rear wheel easy when turned off. When on the drivetrain is under additional tension that makes for a quieter ride and more precise shifting. | Shimano GRX Di2 RD-RX825 12-Speed Rear Derailleur 36t Max
