Reserve 30 HD 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.Built with DT Swiss Hubs featuring DEG 90 points of engagementDesigned for DH riding and racingCarbon fiber construction with 4mm asymmetric offsetReinforced rim bed for impact resistanceRated for e-bike useShips with rim tape installed, tubeless-ready valves, and cards identifying the builder of each of your wheelsBacked by a lifetime warrantyItem SpecificationsCassette Body TypeSRAM XDColorCarbonDefined ColorBlackFront Axle15mm Thru x 110mmHub/Brake Compatibility6-Bolt DiscISO Diameter584 / 650b / 27.5"ISO Diameter622 / Road / 29"Rear Axle12mm Thru x 148mmRim MaterialCarbonRim Width (Internal)30Tire TypeTubeless ReadyValvePrestaWheel Size27.5"Wheel Size29" Reserve Wheels Reserve 30 HD Wheelset Wheelset UPC: 192219481364
