The 30 HD i9 Hydra 29in Boost Wheelset from Reserve is a do-anything wheelset. It's for tackling tough sections of trail, swerving on singletrack, and bombing boulder-strewn descents. A 30mm internal rim width supports tires up to 2. 5in, and Industry 9 Hydra hubs make for snappy, responsive engagement. This wheelset also features an asymmetrical design, which increases strength and stiffness for our ride.
