Shimano GRX RX825 Groupset - Di2 | 2x12-speed | with CS-R8101 Cassette (11-34T)

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 Di2 RX825 – Electrify Your Gravel

More control and integration on the next Gravel adventure – that is the promise of the electronic components of the RX825 series which expand Shimano's GRX family with the proven and at the same time improved Di2 functionality. In the wireless cockpit, sophisticated ergonomics meet Bluetooth connectivity, while the 2x12-speed drivetrain with digital shifting precision, Shadow RD+ chain stabilization and HYPERGLIDE+ technology ensures direct propulsion on any terrain.

Like their mechanical counterparts, the GRX Di2 parts are characterized by control, reliability and performance – whether you are riding at top speed on a flat track, rolling over endless gravel tracks or fighting your way up the steepest climbs. Following the motto "more gears, more possibilities", the chainring gradation of the FC-RX820-2 crankset (48/31 teeth) optimized for Gravel use in combination with the CS-R8101 cassette (11-34 teeth) has a suitable option for any terrain, so that no trail will bring you to your knees anymore.
