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.
We’ve paired this hookless, tubeless ready rim with hubs made just for Astral from our long-time USA made partner, White Industries. Or, upgrade to the elite level Project 321 hub for an all Oregon-made top-tier wheelset. All Astral wheels feature a Tubeless Easy rim profile for painless tire installation and are hand-built by people that care.
