Serpentine Carbon Wheelset (29") Project321 Hubs

The Serpentine Carbon is a fast, light 29-inch xc wheelset. A 30mm internal rim width is ready for wide tires, while its low weight makes for a dependable, nimble and snappy ride. 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%.

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 by people that care.
