Riding is believing with the Zipp 1ZERO HITOP SW MTB wheelset when it comes to making you faster. Trail compliance is vital, with modern cross-country races 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 SW carbon rim 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 the durability required for a trail bike with up to 130mm of travel. A compliant wheel provides more confidence. You don’t have to work hard to spin it up to speed or fight your bike when things get chunky. The 1ZERO HITOP SW also comes with the TyreWiz tire-pressure monitoring system, so you’ll always have your tire pressure dialed in for optimal performance. Among the lightest on the market, the ZM2 SL hubset ensures you’ll be quick to accelerate and back on the pedals sooner after corners with the 1ZERO HITOP SW.
