Learn all about the new 1ZERO HITOP SW and S wheelsets. The 1ZERO HITOP models are Zipp’s first XC wheelsets in almost three decades. The 1ZERO HITOP builds on Zipp’s success in MTB with the 3ZERO MOTO Enduro wheelset. Zipp offers two versions of the 1ZERO HITOP wheel: the premium SW and the dependable S.

The philosophy behind the 1ZERO HITOP is simple: No longer is it good enough for an XC wheelset to be stiff above all else. Instead, a wheelset should feel alive. The 1ZERO HiTOP SW carbon rim’s design complies with the terrain thanks to Zipp’s proprietary HiTOP Technology for carbon layup. The result is a lightweight XC wheel that carries speed through all sections of the trail, rocks, roots, and ruts with dependable durability.

In this episode, Zipp Design Engineer Aaron Packard and Zipp Test Engineer Brian Leathers explain the design, tech, and testing behind the 1ZERO.
