Backbone Wheelset (27.5") Project321 Hubs
*USE SALE CODE HolidayAlloy AT CHECKOUT AND SAVE $100!
The Backbone is a sturdy 30mm 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.
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.
