Shimano GRX RX820 Groupset - 1x12-speed

Shimano GRX RX820 Groupset - 1x12-speed


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.

GRX RX820 1x12 – Unstoppable.

Comfort, reliability and durability. The 1x12-speed version of the GRX RX820 groupset is ideal for days spent exploring the countryside and tackling remote back roads with long climbs. However, its parade discipline is climbing high mountains.

The wide gear range resulting from the combination of CS-M8100 cassette (10-51 teeth) and FC-RX820-1 crankset (40 or 42 teeth) always offers exactly the right gear for the steepest roads or the highest Alpine passes. On difficult trails where a lot of mud really accumulates, the 1-speed crank again shows why less is sometimes simply more. Expand your horizons and make the Gravel tracks your territory!
