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 tyres with low tyre pressure. As a result, the rim behaves reliably both on- and off-road. Designed for ambitious, adventurous cyclists who sometimes ride off-road, this gravel rim gives you an unbelievably direct ride and makes the GR40 the most versatile rim in our portfolio.
