The Shimano GRX RX820 gravel groupset is the leading choice for off-road and gravel enthusiasts. Built on Shimano's sturdy and reliable technology, this groupset is specifically designed to meet the unique demands of gravel and off-road riding. Enjoy unrivalled control and comfort with ergonomic shifters, a versatile crankset and a rear derailleur that never lets you down. Whether you're racing on rough terrain or taking a leisurely ride through nature, you'll always be in your element with the Shimano GRX RX820.
Shifters
The Shimano GRX shifters offer a light and responsive 12-speed mechanical shifting experience, perfect for mixed terrain. The ergonomics are specifically designed to improve comfort by reducing pressure on your palms, while the non-slip coating on the brake surface provides extra control on bumpy terrain. The shifters are even optimised for use with flared handlebars, giving you even more control.
Crank set
The Shimano RX820 1x12 crankset is optimised for gravel. With available chainrings of 40T and 42T and cassettes of 10-45T or 10-51T, riders can choose the perfect ratio for their specific riding style and terrain. Whether you choose tighter gears for the flat or a wide range for the mountains, this crankset offers it all. Moreover, three different crank arm lengths are available (170, 172.5 and 175mm) for extra personalisation.
Rear derailleur
The Shimano GRX 1x12 rear derailleur comes with an integrated clutch, making shifting smoother and quieter, even on the most challenging terrain. This system has a switch for easy wheel changes and is compatible with 10-51T, 12-speed Shimano MTB (Micro-Spline) cassettes. Whether you're climbing a steep hill or tearing across rough terrain, this rear derailleur ensures a reliable and quiet ride.
