Shimano GRX RX825 Di2 2x12 Speed Komponentgrupp

The Shimano GRX RX825 Di2 12 speed groupset combines Shimano's unrivalled electronic shifting technology with a 12 speed gravel groupset, so you can enjoy the best possible shifting performance during your offroad cycling adventures! Compared to the GRX RX820 mechanical groupset, this electronic version features improved Dual Control shifters and a new Di2 rear and front derailleur.

RX825 Di2 Dual-Control shifters
The new Dual-Control shifters of this groupset are designed especially for gravelriders. They feature raised hoods, a textured surface and anti-slip brake levers for ultimate grip and comfort, even in the most challenging circumstances! In addition, the inside of the hood features a third Di2 button, which you can use for shifting, altering your lights, or to, for example, scroll through your bike computer's display! Last but not least, the optimised design fits seamlessly onto flared gravel handlebars. This increases the contact area, decreasing bothersome pressure points. Quite an upgrade!

RX825 Shadow RD+ rear derailleur
The new 12-speed RX825 rear derailleur features Shimano's innovative Shadow RD+ technology. This means it features an on/off switch. When the switch is set to off, you can easily remove your rear wheel, but when set to on, tension on your drivetrain is increased. This makes shifting both a lot easier and a lot quieter! As in road cycling group sets, the rear derailleur of this groupset functions as communication hub for the drivetrain. It communicates wirelessly with your shifters, bike computer and the E-TUBE PROJECT Cyclist app on your smartphone. In addition, both the charging port and a multifunctional button are located on the rear derailleur. This button can be used to easily check your battery's charge level, connect to Bluetooth and activate the customization modes for both derailleurs. The Shadow RD+ rear derailleur weighs 310 grams, is suitable for 11-34 or 11-36 cassettes and features integrated D-FLY connectivity.

GRX RX820 crankset
The Shimano GRX RX820 2x12 crankset was especially designed for offroad cycling. Whether you need precise shifting for flat roads or a wide range of gears for mountainous trails, this crankset has you covered. There's even three different crank arm lengths available (170, 172,5 and 175 mm) for a personalised setup.

FD-RX825 2x12s front derailleur
The front derailleur of this electronic gravel groupset has, like its predecessors, a wider chainline of +2,5 mm, which increases the maximum band width. A sensible choice, considering the trend towards wider tyres and cycling conditions which are often muddy. With a weight of only 142 grams, this front derailleur combines a lightweight construction with advanced shifting technology for ideal performance.
