Backbone Carbon X Wheelset (27.5") Approach Hubs by White Industries

The Backbone Carbon X is a 30mm internal 27.5 trail-slayer. Stiff, robust rims hold a line in any condition and the light weight and smooth carbon-ride perfectly match the flick-ability inherent to smaller wheels.

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 by people that care in Eugene, Oregon.

*9mm conversion available on 15mm thru axle
