Shimano GRX RX825 Upgrade Kit - Di2 | 2x12-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 brings people together in a shared passion. It lays the foundation for friendships and creates memories for eternity. Whether you ride one kilometer or a hundred. With professional equipment or without. With a 10-speed, 11-speed or 12-speed drivetrain. Whether on asphalt roads, forest roads, side roads – or no roads at all. It doesn't matter why you're out there, all that matters is that you are.

GRX Di2 RX825 – Electrify Your Gravel

More control and integration on your next Gravel adventure – This is the promise of the electronic components of the RX825 series, with which Shimano is expanding the GRX family with the proven and improved Di2 functionality. Sophisticated ergonomics meet Bluetooth connectivity in the wireless cockpit, while the 2x12-speed drivetrain with digital shifting precision, Shadow RD+ chain stabilization and HYPERGLIDE+ technology ensures direct propulsion on any terrain.

Feel Electric. The set includes all the necessary components for converting to the electronic shifting system. Like their mechanical counterparts, the GRX Di2 parts are characterized by control, reliability and performance – regardless of whether you are riding at top speed on flat terrain, rolling over endless gravel tracks or battling your way up the steepest climbs.
