Fully wireless shifting built for rough gravel terrain.
Whether you are new to gravel or helped define the category, SHIMANO GRX has an option for you. As the world's first gravel-specific groupset, GRX offers smooth shifting, reliable braking, and exceptional gravel comfort.
The all-new GRX RX827 rear derailleur paired with a 10-51T cassette gives riders and racers the speed, range, and robustness to pursue any gravel challenge. With built-in automatic impact recovery, an impact-deflecting shape, and solid pulleys, this derailleur stands up to hard impacts and still retains its lightning-quick shifting performance.
The SHIMANO FC-RX820-1 crank balances weight savings, optimized efficiency and an array of gearing options that cater to the segmented demands of mixed-terrain riding. By pairing a 10-45T or 10-51T cassette with 40T and 42T chainrings, riders can choose closer gear steps or ultimate range. The FC-RX820-1 comes in 170, 172.5, and 175 mm crank arm lengths, providing an additional level of customization.
CS-M8200 represents the evolution of HYPERGLIDE + shifting. New cassette cog tooth profiles improve shifting under high load while remaining smooth, fast, and durable. It is also MICRO SPLINE compatible and built with steel and alloy cogs to optimize weight and durability. Features 10-51T 510% Range: The widest gear range and most frame compatibility of all DEORE XT cassette options.
The 12-speed SHIMANO GRX Di2 DUAL CONTROL LEVER delivers fast, wireless shifting for gravel and mixed-terrain riding. The ergonomic lever features raised hoods, ribbed surface texture, and an anti-slip coating on the brake lever for increased security and control. The hood body is newly optimized for seamless integration with flared handlebars while retaining the gravel-specific third button location. To complete the cockpit, RX825 levers are compatible with three satellite shifter options and feature SHIMANO FRONT SHIFT NEXT functionality to maximize rider customization options.
