The name Cosmic has always been synonymous with speed and performance. This 65mm version for disc brakes is no exception: when it comes to spinning on the flats and in the wind, it´s the fastest in the family. The 65mm high contoured rim penetrates air with minimal drag; the 26mm wide profile provides great stability against side winds. Another crucial factor in efficiency is rolling resistance. The problem is solved with our reworked UST Road Tubeless System, which makes fitting and changing tires easier than ever.
