A larger wheel changes how a bike handles rough terrain — on gravel and on trail. The 9th Wave 32″ range covers both disciplines: the SandStone SL32 and limited SandStone SL32 LTD for gravel, and the Yarrow SL32 for XC and marathon MTB. All share the same principle: a 32″ diameter rolls over obstacles at a shallower angle than smaller wheels, keeping more speed on broken surfaces and reducing fatigue on long days. Hand-built in the Netherlands, with a lifetime warranty on the carbon rims after registration.
