The XPLR Slick is part of the Goodyear range of Fitment Series bicycle tires, a complete system-based approach to bicycle tire design, where tires are developed and optimized for a specific fitment to maximize performance based on intended usage. The XPLR Slick is our fastest XPLR tire, designed for gravel racing and is optimized around Zipp’s 303 XPLR wheelset. With optimized construction, geometry, and volume maximize aerodynamics and vibration damping, the XPLR Slick is for use on smooth surfaces when speed is high.
