Shimano GRX – United in Gravel

Gravel is the great equalizer. No matter who you are, where you come from or where you want to go. Gravel celebrates individuality. It welds together in a shared passion. It lays the foundation for friendships and creates memories for the ages. Whether you ride one kilometer or a hundred. Whether with professional equipment or without. With a 10-speed, 11-speed or 12-speed gear system. Whether on paved roads, forest roads, back roads – or no roads at all. It does not matter why you are out there, all that matters is that you are.

Shimano GRX FC-RX820-2 crankset

The two-piece Shimano GRX FC-RX820 crank combines low weight with improved efficiency to always cut a fine figure in mixed terrain. The gear ratio of the crankset for 2x12-speed drivetrains is adapted to the different requirements of Gravel use and is ideal for dynamic group rides and aggressive races.

Even on rough surfaces, the close gradation with smaller gear steps ensures a consistent cadence and correspondingly good control, which is necessary to maintain the position in the field. Complementing this, the 17-tooth chainring difference (48/31 teeth) covers a wide range of use, providing a comfortable ride when combined with an 11-34 tooth cassette (CS-R8101-12, sold separately) or 11-36 tooth cassette (CS-HG710-12, sold separately) – whether cruising on flat trails, tackling endless gravel roads or massive backcountry climbs.

HOLLOWTECH II

The guiding principle of Shimano's Hollowtech II technology is the perfect balance between stiffness, stability, weight and rotational efficiency. The goal was to produce a crank that minimises the effort required for the drive and enables more efficient power transmission. An exclusive forging process allows the production of extremely light crank arms that nevertheless guarantee maximum stiffness. The fixed connection of the right arm to the axle of the bottom bracket and its external bearing also serve an optimum relationship between stiffness and low weight.
