Modern XC tracks throw roots, rock gardens, and rutted turns at riders, and Zipp built the 1ZERO HITOP SW to handle that terrain on a hardtail or a short-travel trail bike, rated for forks with up to 130mm of travel.\u003c\/p\u003e\n\u003cp\u003eThe rim is carbon and hookless, using Zipp's proprietary HITOP carbon layup, which is engineered to flex slightly under impact rather than transmitting every hit straight into the rider's hands. That compliance is the point — a wheel that's only stiff can feel harsh and skittish over broken ground, while a wheel with some give tracks the terrain instead of bouncing off it. At a 21.2mm rim depth and 30mm internal width, the profile stays shallow and wide, which suits XC's low-speed, technical demands better than a deeper aero rim would. The rim carries an asymmetrical, winged profile that gives the tire a smoother resting surface at the bead, which cuts down on pinch flats when you clip a rock at speed.\u003c\/p\u003e\n\u003cp\u003eBuilt into the wheel is Zipp's TyreWiz tire-pressure monitoring system, which tracks pressure in real time so you're not guessing whether a wheel has bled air over the course of a rocky descent — useful on a wheel like this, where tire pressure has a direct effect on how well that HITOP compliance actually works. The front hub uses Zipp's ZM2 SL hubset, rated at 66 points of engagement, and is available with standard or Torque Cap axle configurations depending on your fork's spec. This wheel is built for CenterLock disc brakes.\u003c\/p\u003e\n\u003cp\u003eTire compatibility runs 47-71c on tubeless or tubed setups, with a maximum tire pressure of 50 psi. Zipp rates the complete 1ZERO HITOP SW wheelset — front and rear together — at a maximum recommended system weight of 286 lbs (130kg), and lists the lightest full wheelset configuration at roughly 1,375 grams. \u003c!-- VERIFY: Zipp's spec sheet for this model lists driver body options (XD, Microspline) as part of the full wheelset listing, but those apply to the rear wheel's freehub — confirm this isn't relevant to the front-wheel-only SKU being sold here before publishing. --\u003e\u003c\/p\u003e\n\u003cp\u003eThis front wheel makes the most sense paired with a matching 1ZERO HITOP SW rear wheel, built out as a full set for a cross country racer or trail rider who wants a lightweight, compliant setup that can handle a technical course without beating up the rider in the process. It's a wheel for someone racing or riding hard enough that both weight and trail feel matter equally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Zipp","offers":[{"title":"Black","offer_id":43522093711404,"sku":"00.1918.719.000","price":975.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/zipp-1zero-hitop-sw-disc-brake-centerlock-29-wheel-front-4309502.jpg?v=1771295948","url":"https:\/\/ricycles.com\/products\/zipp-1zero-hitop-sw-disc-brake-centerlock-29-wheel-front","provider":"RA Cycles","version":"1.0","type":"link"}
