Specialized Pathfinder TLR 700c Tire Lighter. Faster. Tougher. Better than ever. An already legendary tire in the world of fast gravel riding and racing, this new Specialized Pathfinder TLR Tire upgrades this ultra-popular tire to make it faster, lighter, tougher, and just plain better than before. The lightest, fastest tubeless gravel tire in the Specialized lineup, the Pathfinder TLR features the tried-and-true fast center tread with a fast-rolling GRIPTON T2 compound for unmatched straight-line speed. The tread opens up toward the edges for increased control, with the extra-grippy GRIPTON T5 compound for added control when leaning into loose corners. This Pathfinder TLR is made with a 3-ply, 60 TPI, tubeless TLR casing to maintain ride quality and durability. The result is a Pathfinder that's 25g lighter (and more cut resistant) than its predecessor, and 19% faster than any gravel tire Specialized has tested before. That's one heck of an upgrade.
