The Reserve 30 was specifically designed for trail riding and the rigors of trail biking. Modern trail bikes are built to handle anything you throw at them. From cruising smooth singletrack to tackling rocky steeps, they offer all-around performance that inspires riders to go faster and smoother. They're 30 mm wide and designed for use with 2.5-inch tires. The redesigned rim base makes it easier to install new tires.
