Zipp’s 1ZERO HITOP SW and 1ZERO HITOP S wheelsets reimagine what’s possible with a cross-country wheel. Trail compliance is vital for modern cross-country riders, whether you’re on light trail bikes, hardtails, or full suspension with up to 130mm of travel. Your wheel should feel alive. Modern cross-country courses are becoming rougher and more challenging. Zipp’s proprietary HITOP carbon layup makes for a compliant wheel, so you’ll rip through rocks, ruts, and roots without losing speed, traction, or confidence. You choose from the premium and ultra-light HITOP SW, which comes with TyreWiz 2.0 for real-time tire pressure monitoring, or the rough-and-ready HITOP S version.
