Ultra light weight, ultra durable. Utilizing the state of the art manufacturing processes and cutting edge technology, Loaded Precision's X-lite Ultra Wheelsets are quite possibly the strongest and lightest tubeless carbon fiber mountain bike rims available today. We use a Carbon Knitting Technique (CKT), securing the carbon layers together through a refined knitting and bonding process. All X-lite Ultra Wheelsets feature True Bead Technology- Loaded’s very own Tubeless System that provides an efficient interface between the tire and rim for easy installation and inflation. Our X-lite Ultra Wheelsets feature either our X-lite V.2 Hub, DT Swiss 180 Ceramic Hub, or DT Swiss 240 Hub. These race-ready wheels are hand laced in San Diego.
