Zipp 1ZERO HITOP S 29" Rear SRAM XD 12x148mm Standard Wheel

Zipp 1ZERO HITOP S 29" Rear SRAM XD 12x148mm Standard Wheel

The Zipp 1ZERO HITOP S is built for cross-country and down-country riders who want a light, wide carbon wheel that holds its line on rough ground. With a hookless carbon rim running a 30mm internal width, an asymmetrical profile, the Zipp ZM900 hub with 52 points of engagement and a 24-spoke CX-Sprint J-bend build, this is a serious carbon mountain wheel at a more accessible price.

At Mackay Cycles, we see the 1ZERO HITOP S as a genuine upgrade for riders wanting lower rotating weight and faster engagement without giving up trail durability, around Mackay and beyond.
