The Zipp Goodyear/Zipp XPLR SLICK Tubeless Tire, part of the XPLR wheel and tire system, takes a new approach to achieving the fastest, most efficient gravel setup on the market with its optimized construction and geometry. The Dynamic:UHP compound offers exceptional grip and low rolling resistance and performs best on smooth to moderate gravel sections on a dry day, and the use of M:Wall protection helps reduce the chance of an unwanted flat tire during the middle of our ride.
