This is the rim behind our 4-Shore wheelset: 42mm deep, 33mm internal, hookless and rated for tires from 40mm up to 62mm. Wide enough to keep a wide tire fully supported at the low pressures beach racing calls for.
The ART asymmetric rim design keeps spoke tension even front and rear. Tubeless ready, and hand built in the Netherlands to the same standard as every 9th Wave rim.
