The Backroad GRX RX820 gives you the freedom to try out just about anything. A well-balanced all-rounder for fast gravel roads, tricky root paths or sweaty climbs.
The extremely versatile frame concept of the Backroad Carbon meets a mechanical 1x12 gravel drivetrain from Shimano. This gives you a huge range of gears that can be shifted quickly and reliably, even off-road. The necessary grip and comfort are provided by wide gravel tyres from WTB, which roll on light and robust G30 LIGHT aluminium wheels.
The wide gravel handlebar from Ritchey is not only easy to control, but also offers first-class ergonomic comfort. The flexing seat post also provides relief at the rear. Whether sporty, fun or touring – with this bike you decide.
More long distance | Endurance
Flex is fun: The deep cut-out in the seat tube provides a massive increase in comfort, while the balanced frame geometry offers perfect handling on the road, gravel and technical terrain. Only a dry throat can stop you.
More off-road | Action
The frame and fork allow for a tyre width of up to 45 mm with 700c and up to 47 mm with 650b wheels. For rougher road conditions, perfectly adapted protectors at the down tube and chainstays protect the paint.
More experience | Adventure
Thanks to its many attachment points for bottle cages, Anything Cages or bags, the Backroad offers ultimate versatility, perfect for a day trip or bikepacking adventures.
