Trail compliance is vital, with modern cross-country races becoming rougher and more challenging. No longer is it good enough for an XC wheelset to be stiff above all else. The 1ZERO HITOP SW carbon rim complies with the terrain thanks to Zipp's proprietary HITOP Technology for carbon layup. The result is a lightweight XC wheel that carries speed through all sections of the trail, rocks, roots, and ruts with the durability required for a trail bike with up to 130mm of travel. ZM2 SL hubset, with 66 points of engagement, ensures you'll be quick to accelerate and back on the pedals sooner after corners with the 1ZERO HITOP SW. The winged rim provides a smooth resting surface for the tire, reducing the chance of pinch flats after a rock hit TyreWiz 2.0 tire-pressure monitoring system included Lifetime Warranty SRAM Model ID: WH-1ZRO-HTSW-A1table{border-collapse:collapse;width:100%;}td{text-align: left;padding: 8px;font-weight:350;}tr:nth-child(even){background-color:#f2f2f2}th{background-color:#eb212e;color:white;text-align:left;padding:8px;}.desc ul{font-size:24px;font-weight:600;margin-left:-25px;padding-top:35px;border-top:3px solid #f0f0f0;}.desc li{list-style:none;border-bottom:4px solid #eb212e;width:142px;} TECH SPECSAxle Type12mm TAFreehub BodyShimano Micro SplineHub ModelZM2 SLHub Spacing148mmPositionRearRim ColorBlackRim ConstructionDouble wallDepth21.1mmRim Drilling24Rim External Width37.7mmRim Internal Width30mmRim MaterialCarbonRim Model1ZERO HITOPSkewers IncludedNoSpoke TypeSapim CX-RayValvePrestaWheel-Brake Comp.Disc Center LockWheel Diameter/ISO29 / 622Wheel Tire TypeTubeless ReadyRim inner width range28-34.9mm
