Backbone Carbon Wheelset, 27.5", Astral Approach hubs
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.
Our Approach hubset is built for Astral Cycling by long-time partner White Industries. It includes the same internal mechanisms as their classic CLD hub, but features a bomber heat-treated steel freehub body rather than titanium.
All Astral wheels feature a Tubeless Easy rim profile for painless tire installation and are hand-built by people that care in Eugene, Oregon.
