Zipp 1Zero Hitop SW wheelset - evolution of XC racing
The Zipp 1Zero Hitop SW hookless bead carbon wheels represent the latest sign that XC-mountain bike racing continues to evolve in terms of trail difficulty and what is expected of the equipment. Tougher, challenging, more technical trails are becoming the norm so Zipp has answered the call of cross-country riders who were looking for a more compliant, lightweight wheel that could carry the wider rubber that modern XC trails and races require.
Using their HITOP Technology, Zipp engineers have given these rims a proprietary carbon layup that introduces an uncommon level of compliance to help the rim handle the rougher trail courses with confidence, without losing any of the usual durability that makes them usable for mountain bikes with up to 130mm of travel. And since this is XC-specific, they are also crazy lightweight, at just 1325 grams. Since they are so lightweight, they get up to speed super fast and keep the bike feeling planted even when you are negotiating a rough section of trail. And the winged rim hookless bead profile with an interior width of 30mm offers a smooth resting surface for the tire, which will reduce the chance of pinched flats.
TyreWiz pressure monitoring system in the 1Zero Hitop SW
The 1Zero Hitop SW are also special because they come equipped with the TyreWiz tire-pressure monitoring system on front and rear. Tire pressure is a huge issue for every discipline, but perhaps no more so than XC racing where maintaining your desired pressure for any given course could be the difference between winning and not even finishing. Weighing just 10 grams, the TyreWiz 2.0 can alert you via a blinking light when your pressure is exactly where you want it set, or when it goes over the desired PSI, as well as under it.
Using the ZM2 SL hub with 66 points of engagement, the Zipp 1Zero Hitop SW wheels roll smoothly when coasting and engage instantly, as soon as you start pedaling again, so you’ll never waste an ounce of effort. The asymmetrical rim profile ensures that the wheels can optimally withstand the power you’ll be hammering through the pedals. Zipp sets a rider/bike system weight limit at 286 lbs / 130 kg, but offers a lifetime warranty on the wheels, which shows the extent of their confidence that the Zipp 1Zero Hitop SW are lightweight XC-racing wheels that can go the distance.
