Zipps new cross-country wheel is here. Introducing the Zipp 1ZERO HITOP SW Carbon wheel, a modern cross-country wheel that has the stiffness and low weight on par with race wheels and the durability and capability to send it down trails. This wheel comes with Zipp's new ZM2 SL hubset that gives us 66 points of engagement for fast acceleration on technical climbs. The 1ZERO HITOP SW Carbon Wheel comes with the TYRE WIZ 2. 0 valve which provides us with precise tire pressure data to let us know when our tire pressures are outside of our target range. An inner rim width of 30mm makes this rim super capable and stable on rough terrain and the hookless bead allows for a smooth resting spot for the tire to resist pinch flats. This wheel is available as a front or rear specific wheel with 15 x 110mm or 12 x 148mm boost spacing for maximum stiffness and durability. Weighing in at 1325 grams, the 1 ZERO HITOP SW carbon wheel is ready to race and packs a ton of capability for its weight class. Other notable features of the SW are the baked on decals that reduce weight, and providing us with high-quaility graphics that are clear coated for durability.
