Why We Like The Zipp 1ZERO HITOP S Carbon Wheel

Zipp's new high-performance, cross-country wheel is here: Introducing the Zipp 1ZERO HITOP S Carbon Wheel, a modern cross-country wheel that has the stiffness and featherweight construction to race on, and the durability and capability on par for ripping down trails. This wheel comes with Zipp's new ZM900 hubset that gives us 52 points of engagement for fast acceleration on technical climbs. 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 boost spacing for maximum stiffness and durability. Weighing in at 1495 grams, the 1 ZERO HITOP S Carbon Wheel is ready to race and packs a ton of capability for its weight class.
