Reserve 30 wheels feature a 30mm internal width that supports 2.3-2.5" tires, and the thick rim beads stand up to the abuse of tough, rocky, steep tracks ridden at elite speed. While DH rims see greater single impacts, nothing beats the full weekend of regular abuse that an EWS race dishes out. To say nothing of the infamous 'Anti-Grip' and the rocks buried within the moondust in the Andes of Chile.
