Backbone Wheelset (27.5") Project321 Hubs
The Backbone is bombproof 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 32mm internal width it’s perfect for wide trail tires.
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 in Eugene Oregon by people that care.

*We do our best to ship your wheel order ASAP, but because many wheel orders are built to order, please allow up to one week for shipment once your order is processed. Custom orders like color decals may take up to one week.
