Zipp’s 1ZERO HITOP S MTB 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. The 1ZERO HITOP S features the dependable ZM 900 hubset.

• HITOP Technology produces proprietary rim layup to provide compliance and confidence when the trail gets rough
• Low weight for effortless accelerations and climbing
• Winged rim top provides a smooth resting surface for the tire, reducing the chance of pinch flats after a rock hit
• ZM 900 SL hub with 52 points of engagement for fast acceleration
• Standard or Torque Cap options on the front hub
• XD or Microspline driver-body options
• TyreWiz tire-pressure monitoring system sold separately
• Lifetime warranty
