Zipp entered the mountain bike market nearly four years ago with its 3Zero Moto wheels, targeted at trail and enduro riders. The brand’s new range is marketed at cross-country riders, who prioritise lightness and efficiency.
Rim specification is what you’d expect from a carbon cross-country wheelset, with a bead profile shaped to reduce pinch flats and an internal diameter of 30mm. The generous internal diameter measurement, especially for an ultra-lightweight carbon rim, should comfortably seat 2.4in casing tyres, with Zipp’s recommending anything in the 2.3- to 2.5in width range.

Like the brand’s 3Zero Moto wheels, Zipp’s industrial designers have shaped the HiTops with a rim profile, enhancing compliance and reducing rider fatigue on harsh terrain. Instead of a single wall design, it features a box section structure, capable of better absorbing and dispersing terrain harshness.
The cleverest feature of Zipp’s cross-country wheelset is an integrated TyreWiz 2.0, available on the lighter HiTop SW wheelset. This device links to your Smartphone and is mounted on the valve. It delivers real-time tyre pressure information while blinking green or red lights on the TyreWiz 2.0 also gives riders a visual reference confirming whether their tyres are at the desired tyre pressure.

Regarding weight and hub engagement, the £2,000 1Zero HiTop SW is rated at 1,325g and features an AMS SL rear hub with 66 engagement points.
The more affordable HiTop S wheelset weighs 1,495g, and its ZM 900 SL hub engages across 52 points. Without the TyreWiz 2.0 and spinning a cheaper rear hub, the HiTop S is priced at £1,400.
