Shimano GRX 820 1x12-Speed Gravel Groupset
Powerful braking, smooth shifting and a wide gear range to suit modern day gravel riders. GRX 820 12-speed groupset with a single front chainring is a performance groupset available in standard or wide.
This is a standard groupset which is compatible with up to 45 tooth cassette ratio.
Shimano GRX 820 Hydraulic & Shift Lever
The SHIMANO GRX DUAL CONTROL LEVER delivers light and responsive mechanical 12-speed shifting for mixed-terrain riding and racing. The ergonomic shifter design improves comfort by decreasing pressure on your palms, while the textured, anti-slip brake lever surface increases control on bumpy terrain.
Shimano GRX 820 Shadow 12-Speed Rear Derailleur
The new 12-speed rear derailleur features enhanced chain security and quieter shifting for gravel riding. The rear derailleur has an integrated chain stabiliser and medium cage length for better ground clearance and more secure chain management in rough terrain. The RD-RX822-GS is compatible with 10-45T, 12-speed SHIMANO MTB cassettes, and the chain tensioner has an ON/OFF switch for easy wheel removal.
Shimano GRX 820 Single Chainset
The SHIMANO FC-RX820-1 crank balances weight savings, optimised efficiency and an array of gearing options that cater to the segmented demands of mixed-terrain riding. By pairing a 10-45T 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.
Shimano GRX 820 Flat Mount Brake Caliper
The GRX BR-R820 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.
