Zipp unveils the 1Zero HiTop SW cross-country carbon wheels

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.
