The Serpentine is a light weight 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 precise handling you can rely on. Add a 30mm internal width for ideal support of fat rubber.
All Astral wheels feature a Tubeless Easy rim profile for painless tire installation and are hand-built by people that care.
