The Zipp G40 XPLR Tubeless Tire is made for comfort and control on the toughest terrain. This tire features a wide 40mm width to assure confidence on difficult rides. The tread pattern started with a chevron center-tread pattern for speed which translated into an inverted soccer cleat design. It also added XC-style knobs at the edges for the ability to dig into dirt when needed. A bead to bead puncture protection strip gives this tire top durability without sacrificing its performance. The Zipp G40 XPLR Tubeless Tire is just what gravel riders need for their off-road adventures.
