There’s a moment on rough gravel when the terrain stops cooperating — loose stone, a rut across your line, a descent where concentration replaces pace. With a 700c wheel, that moment may cost you speed. With a 32-inch wheel, it largely doesn’t. The larger diameter approaches obstacles at a shallower angle, rolls over them with less disruption, and holds momentum where a smaller wheel would scrub it. That’s not a claim — it’s geometry.
The SandStone SL32 brings that advantage to a carbon wheelset built on the same rim profile that defines the SandStone line: 52mm deep, 37mm internal width, hookless tubeless ready, with ART asymmetric rim technology for even spoke tension across both sides. The same geometry that made the SandStone SL 700c a reference point for wide-tire gravel riding, now on a BSD 686mm hoop optimized for tires from 50mm upward.
The legitimate question about any 32-inch wheel is stiffness. The SandStone SL32 addresses it at four levels — rim depth, spoke count, Boost axle standard, and ART asymmetric geometry — and the result matches or exceeds a well-built 700c gravel wheelset. At 1,514g, it’s very competitive for a wheel this size and this wide. The weight earns its place.
Hand built in the Netherlands with rim tape and valves installed, and once you register your wheels, the carbon rims are covered for life.
Curious how those four levels work together — and what 32 inches actually measures with a 50mm tire fitted? Read our journal article on the SandStone SL32.
