Zipp 1Zero HiTop S Carbon Mountain Bike Wheel - Tubeless Ready, 29"

The Zipp 1Zero HiTop S is a carbon 29" XC and trail wheel offered here as a front (15x110mm, 6-bolt) or rear (12mm thru-axle, Shimano Micro Spline). Zipp builds it for rough modern XC courses and trail bikes with up to 130mm of travel.

What sets it apart is the rim layup. Zipp's HiTop technology tunes the carbon to comply with the terrain rather than chase stiffness alone, and the winged rim gives the tire a smooth resting surface that Zipp says reduces pinch flats after a rock hit.

Who It's For

• XC racers and trail riders on 29" bikes with up to 130mm of travel
• Front: forks with a 15x110mm thru-axle and 6-bolt rotors. Rear: 12x148mm frames with Shimano Micro Spline cassettes
• Not for SRAM XD/XDR or HG cassettes, or longer-travel enduro bikes

What to Look For

• Wheel size: 29" (622 ISO)
• Front option: 15mm thru-axle x 110mm, 6-bolt rotor mount
• Rear option: 12mm thru-axle x 148mm, Shimano Micro Spline driver

Key Features

Rim: Carbon, 24 holes, hookless, 30mm internal. The HiTop layup is built for compliance, which Zipp says brings confidence when the trail gets rough, and the low weight helps acceleration and climbing.

Hub and spokes: Sapim CX Sprint spokes laced to Zipp's ZM 900 hub.

Tires: Hookless rim that runs tube-type or tubeless tires, with a Presta valve. Compatible with the TyreWiz tire pressure monitoring system, sold separately.

Warranty: Zipp backs the wheel with a lifetime warranty.

Rider Intent Summary

• Biggest strengths: compliant HiTop carbon rim, low weight, lifetime warranty
• Tradeoffs: 24-hole XC build capped at 130mm travel; rear offered in Micro Spline only
• What makes it different: a carbon layup tuned for compliance, not just stiffness

Victory's Take

At Victory Bicycle Studio, we'd steer XC racers and short-travel trail riders to the 1Zero HiTop S when they want carbon that takes the edge off rough courses. Select front or rear carefully, since the two options fit different hardware.
