ZIPP 1ZERO HiTOP SW 29" Wheelset - SRAM XDR

The Zipp 1ZERO HiTOP SW 29" Carbon MTB Wheelset is purpose-built to meet the demands of today’s modern and increasingly rough cross-country trails, where agility and liveliness are just as important as stiffness. With courses becoming more technical and challenging, Zipp has developed a wheelset that feels alive under you, delivering responsiveness and compliance for maximum control and comfort over rocks, roots, and ruts.

At the heart of its performance is Zipp’s advanced HiTOP Technology carbon layup, designed specifically for off-road conditions. This unique rim construction combines lightweight efficiency with a forgiving ride quality, allowing you to maintain speed through every section of the trail. Strong enough for use on trail bikes with up to 130mm of travel, the 1ZERO HiTOP SW offers effortless climbing, rapid acceleration, and stability when the terrain gets unpredictable.

The smooth-running ZM2 SL hubs with 66 points of engagement ensure immediate power transfer, while the wide rim flanks provide a solid contact surface for the tire, reducing the risk of pinch flats from stone impacts. Adding another layer of precision, the 1ZERO HiTOP SW is equipped with the Zipp TyreWiz tire pressure sensor. This lightweight and durable device monitors air pressure in real time, transmitting data directly to your bike computer or smartphone. Powered by an easily replaceable button cell battery, the TyreWiz app processes this information to deliver personalised pressure recommendations and alerts, giving you the ability to make informed decisions that directly impact rolling resistance, traction, tire wear, and ride comfort. For the first time, riders can access accurate, real-time tire pressure data to optimise performance every ride.
