The Backbone Carbon is a 28mm internal width mountain bike wheel, ready to work hard on the climbs and rip back down. A balance of precision steering, light weight and durability make this the perfect 27.5 inch mountain bike wheel for any occasion.
Made just over the mountains from us in Bend, Oregon, Project 321 hubs offer absurdly fast, 216-point engagement and light-yet-strong alloy free-hubs. We use their “loud” pawl system for rock-solid reliability.
All Astral wheels feature a Tubeless Easy rim profile for painless tire installation and are hand-built by people that care in Eugene, Oregon.
