Contact us for availability and Special Orders! The GR40 is a gravel rim that can deal with road riding and was developed from the aerodynamically optimized RR40 and the impact-resistant XC30. The geometry, reinforced rim flange and layup of the GR40 gives you the option of riding high-volume tires with low tyre pressure. As a result, the rim behaves reliably both on- and off-road.Handmade in Germany.
