Our most popular gravel tire is designed to handle compact terrain, intermediate gravel, and consistent to looser dirt roads – in other words, many of the conditions encountered daily. It is likely the first choice for races or major rides, to be replaced only in case of very wet or rocky routes with coarse gravel. For higher speeds, lower pressures, and more demanding terrain, Challenge has developed a new technology applied to handcrafted construction. The new XP series adds extra protection on the sidewalls and tread (Xtra Protection - XP) for increased durability.
