The Backbone Carbon is a 28mm internal width full carbon mountain wheel, ready to work hard on your climbs and laugh all the way down. The balanced width is perfect for chunky rubber and the gnarliest of trails, but keeps weight within xc realm. Spin up fast, rip down faster. From and trail cruising to air time bruising, the Backbone Carbon fits the bill.
