A larger wheel changes how a bike handles rough terrain, on gravel and on trail. The 9th Wave 32 inch range covers both: the SandStone SL32 and the limited SandStone SL32 LTD for gravel, and the Yarrow SL32 and carbon-spoke Yarrow SL32 Ninefold for XC and marathon MTB. A 32-inch 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. Gravel rider? Read why 32-inch wheels belong on a gravel bike.
