Shimano GRX RX825 Di2 Groupset

The Shimano GRX RX825 Di2 brings the precision of electronic shifting to a versatile 2x12-speed setup for gravel cyclists. This system uses a smart semi-wireless configuration: the shifters communicate wirelessly with the rear derailleur, while the derailleurs are connected via cables to a central battery for maximum reliability and long battery life. This ensures a clean cockpit without compromising shifting speed. Whether you're climbing or sprinting, shifting is direct and smooth, even under heavy load, thanks to Hyperglide+ technology.

The ergonomics of the shifters are specifically designed for unpaved terrain. The grips have a textured surface for extra grip and a shape that perfectly matches flared handlebars, reducing pressure on the hands. The hydraulic disc brakes are equipped with Shimano's Servo Wave technology, which allows the brake pads to engage faster, giving you more control on technical descents. The buttons can be fully customized via the E-TUBE app, including the convenient "Front Shift Next" option to operate the front derailleur with a single button.

With the 2x12 drivetrain, you benefit from small steps between gears for optimal cadence and a wide range for steep climbs. The rear derailleur features the integrated Shadow RD+ chain stabilizer, which prevents chain slap and keeps the drivetrain quiet on rough trails. The combination of robust durability and refined electronics makes the RX825 the ideal choice for enthusiastic gravel riders who demand top performance in all conditions.
