Shimano GRX RX827 1 x 12 Speed Di2 Groupset
Shimano GRX RX827 1x12 Speed Di2 Groupset
The Shimano GRX RX827 1x12 Speed Di2 groupset is purpose-built for gravel riding, delivering precise electronic shifting, exceptional chain control, and reliable performance across mixed terrain. Designed for riders who demand simplicity, durability, and race-ready technology, RX827 is ideal for gravel, adventure, and all-road bikes.
GRX Di2 Dual Control Lever
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. 3 to 4 years of battery life with easy-to-change CR1632 shifter batteries (Initial shifter batteries may have a shorter battery life than stated above.)
GRX Di2 REAR DERAILLEUR 1x12s
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.
GRX CRANKSET - 1x12s
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.
GRX - FLAT MOUNT - BRAKE CALIPER
The GRX BR-RX820 disc brake caliper brings a new level of control to gravel cycling with enhanced modulation and a quicker initial braking point. And despite its smaller construction, the system is quieter and easier to maintain.
