Modern trail bikes are designed to tackle anything that can be thrown at them. From cruising mellow singletrack to crushing boulder-strewn steeps, they deliver a do-everything performance that inspires the rider to go faster, more smoothly. The Reserve 30|HD is specially designed for trailing riding and the abuse trail bikes dish out. They feature a 30mm width for use with 2.5 tires and a redesigned inner rim bed that takes the hassle out of seating new tires. FEATURES: DT Swiss Degree of Freedom: Unlock your suspension's full potential and improve performance with the new DT Swiss Degree of Freedom hubs, exclusive to Reserve Wheels. Tune engagement to your riding style with 0°, 10°, or 20° settings to reduce pedal kickback and improve suspension performance. At 0°, the hub functions as a standard high-engagement hub, with 90 teeth and 4° of engagement. Degree of Freedom equipped hubs also improve freespin with a low-drag design, remove drivetrain chatter and chain feedback. This supercharges your bike’s suspension performance without adding a single gram of extra weight to your wheelset. Asymmetrical rims, like these on the 30|HD, build stiffer, stronger and more reliable wheels by improving the bracing angles and equalizing the spoke tensions between the drive and non-drive side spokes. The 30|HD's redesigned rim bed eases tubeless installation, with a shaped rim bed utilizing offset spoke holes that allows the tire to easily push past the bead bump to seat tubeless tires.
