Backbone Wheelset, 27.5", Astral Stage 1 hubs
The Backbone is sturdy 32mm internal 27.5 trail wheelset mountain bike wheelset. We improve the stiffness, strength and longevity of a wheel by using an asymmetric (ASYM) rim design than improves spoke tension balance by up to 30%. On the trail, this translates to balanced handling you can rely on in even the ruggedest of terrain. With a 30mm internal width it’s perfect for wide trail tires.
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 at a nominal 28 gram weight sacrifice.
All Astral wheels feature a Tubeless Easy rim profile for painless tire installation and are hand-built in Eugene Oregon by people that care.
