Zipp 1Zero HITOP S Boost 29-inch carbon MTB wheels

The Zipp 1Zero HiTop S are high-end 29-inch wheels designed for cross-country and down-country mountain biking. These wheels stand out from the competition by offering an incredible balance between lateral stiffness and vertical flexibility. In practice, the Zipp 1Zero HiTop S will allow you to be efficient in your accelerations and on the physical sections while having excellent shock absorption capacity. You can tackle technical sections strewn with stones and roots with confidence thanks to the carbon rims with an internal width of 30 mm, which help to smooth out the various obstacles you encounter. These features are made possible by the low rim height of just 21.2 mm, which optimises the vertical flexibility and precision of these wheels on winding and chaotic trails. To get the most out of these advantages, we recommend tubeless-ready mounting with tyres ranging from 2.30 to 2.40 in section, depending on the intended use. This mounting will also significantly reduce the risk of punctures.The rear wheel is equipped with a 52-point engagement freewheel body, which provides quick pedalling recovery when exiting corners.The Zipp 1Zero HiTop S features the same UD carbon rim as the higher-end 1Zero HiTop SW, with the difference being in the hub model. In addition, the 1Zero HiTop SW comes with the TyreWiz 2.0 pressure sensor as standard, whereas this sensor is only available as an option on the Zipp 1Zero HiTop S.GENERAL CHARACTERISTICS:¤
