The 1Zero HiTop S wheelset melds high value with high performance for a better and faster ride. Trail compliance is vital, with modern cross-country courses becoming rougher and more challenging. 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 S carbon rim complies with the terrain thanks to Zipp's proprietary HITOP Technology for carbon layup. The result is a light XC race or adventure wheel that carries speed through all sections of the trail, rocks, roots, and ruts with the durability required for a trail bike with up to 130mm of travel. A compliant wheel provides more confidence.
