Zipp 1ZERO HITOP

This wheel is engineered specifically for cross-country racing and trail riding. It is an ideal upgrade for trail bikes with up to 130mm of travel, balancing the lightweight needs of XC with the durability required for rougher trail terrain.

HITOP technology allows the carbon rim to flex slightly when it encounters obstacles like roots or rocks. This compliance helps the wheel track better over rough ground, smoothing out the ride and maintaining your momentum where stiffer wheels might deflect.

Yes, the rim features a unique winged profile that provides a wider, more stable surface for the tire bead. This design significantly reduces the risk of pinch flats, allowing you to run lower tire pressures for better traction without worrying about damaging your tire or rim.

The 1ZERO HITOP rear wheel is compatible with Shimano Micro Spline cassettes and uses a 6-bolt disc brake interface. Please ensure your frame is compatible with a 12mm thru-axle setup before purchasing.

The ZM 900 SL hub features 52 points of engagement. This provides a quick, responsive feel when you start pedaling, which is particularly helpful for technical climbs or navigating tight trail sections where immediate power transfer is critical.

Yes, the rim is tubeless-ready out of the box. Given the wheel's design, running a tubeless setup is highly recommended to take full advantage of the pinch-flat protection offered by the winged rim profile.
