The Backroad GRX RX820 2x12 – a gravel bike with real racing vibes. Those who love long distances will get the full experience here.
The basis is the smooth-running carbon frame, on which Shimano's mechanical gravel top group with a double crank is installed – for fine gear steps and maximum pedalling efficiency. The lightweight G30 LIGHT aluminium wheels also get you up to speed quickly and, in combination with snappy WTB gravel tyres, provide propulsion on any surface.
If things get bumpy, you can rely on Ritchey's wide-spaced gravel handlebar. In addition to the necessary control, it also offers plenty of comfort and excellent ergonomics. So your arms don't get tired even after endless kilometres of gravel.
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.
¹ Weight: approx. 9.0 kg. May vary by up to +/- 5% due to manufacturing tolerances. Weight with frame colour blue haze, size 57 cm, without pedals.
