Zipp 1ZERO HITOP S Disc Brake 6-Bolt 29" Wheel - Front Info

The Zipp 1ZERO HITOP S Disc Brake 6-Bolt 29" Wheel - Front is the front half of Zipp's cross-country wheel platform, sold individually for riders building a custom wheelset or replacing a single wheel rather than the full pair. It sits below the flagship HITOP SW in Zipp's lineup, trading a small amount of weight for a lower price while keeping the same core rim technology that makes the HITOP series distinct from a typical XC carbon wheel.

That technology is Zipp's HITOP carbon layup, engineered to flex in a controlled way rather than transmit every trail impact straight into the rider's hands. Modern cross-country courses have gotten rougher, and a rim that's simply stiff everywhere tends to bounce off roots and rock gardens instead of tracking through them. The HITOP layup is built to absorb some of that hit at the rim itself, which shows up as more confidence on the rough sections of a course rather than a smoother ride in isolation. Zipp rates the wheel for trail bikes with up to 130mm of travel, putting it in that gray zone between race-focused XC and light trail riding rather than a pure cross-country race rim.

The rim itself is a hookless carbon construction, 21.2mm deep, with a winged profile that flares slightly at the tire bead. That flare adds support right where a tire is most likely to pinch against the rim on a hard hit, reducing the chance of a pinch flat without adding a hooked bead's weight or complexity. It's finished in unidirectional carbon fiber with adhesive decals rather than a painted graphic, keeping weight down where it doesn't need to be added back. The wheel is compatible with tube-type or tubeless tires, and Zipp specs a maximum tire pressure of 50psi and a maximum system weight of 286 lbs, both reasonable figures for a rim built around trail compliance rather than maximum stiffness.

Zipp's ZM 900 hub drives the wheel, built around 52 points of engagement. That's not the highest engagement count on the market, but it's enough to keep power delivery responsive out of corners and off the line without the buzz or added drag some ultra-high-engagement hubs introduce. The hub uses a 6-bolt disc brake interface, keeping it compatible with a wide range of rotor options rather than locking a buyer into a single brake ecosystem. For riders who want real-time tire pressure feedback, the wheel is also compatible with Zipp's TyreWiz pressure system, sold separately here on the S tier rather than bundled in as it is on the SW.

At $650 for the front wheel alone, this is a way into Zipp's HITOP platform for a rider who wants that rim compliance and pinch-flat resistance without paying flagship SW pricing, or who's mixing and matching wheels for a specific build. It's finished in black and built for 29" wheel platforms.

The RA Perspective

We like the 1Zero HiTop S because it brings real rim compliance to cross-country wheels without asking a rider to step up to Zipp's SW pricing. Courses have gotten rougher over the last few seasons, and a wheel that's designed to flex a little at the rim instead of fighting every root and rock actually helps on those technical sections, even if it sounds counterintuitive for a race wheel.

The 52-point-of-engagement hub is a reasonable middle ground — it's not going to feel as instant as a top-tier freehub, but we haven't found it lacking on punchy XC climbs or technical singletrack either. The hookless rim and winged bead profile do a good job resisting pinch flats on hard hits, which matters more on trail-influenced XC courses than on a smooth criterium-style track.

Since this is sold as a single front wheel, it's worth knowing this is really built for someone assembling a specific wheelset — maybe pairing it with a different rear hub, or replacing one damaged wheel rather than buying a full set. If you're building a complete pair from scratch, buying front and rear together usually makes more sense than piecing it together this way.

We'd point riders here who want HiTop's trail compliance and pinch-flat protection at a more accessible price than the SW, especially anyone riding rougher, more demanding XC terrain rather than smooth race courses.
