The latest tire in Specialized’s adventure lineup is the Pathfinder, and it’s designed to bridge the gap between their very fast rolling, minimally treaded Sawtooth and the knobbier (for a gravel tire) Tracer. In fact, they say it’s for rides when you’re rolling on road and off in roughly equal parts.

A smooth center tread ring provides contiguous rubber for smooth rolling. Diamond shaped darts fill in the transition area, with slightly larger versions spaced a bit more apart on the outer cornering edge. It’s all made of their Gripton compound to provide solid traction in all directions

Underneath is their BlackBelt puncture protection layer, followed by three layers of their 120tpi Endurant casing construction so it’ll hold up to roots and rocks without getting sidewall tears. Specialized boasts that this combo has four Dirty Kanza 200 wins.

  1. When I first started riding (way before #putagravelonit was a thing), my boss in Iowa told me that to make a gravel tire, you just rode a set of CX tires until the center tread wore down smooth. Thank you, Specialized, for vindicating him.

    • I have the 650×47 version mounted to some Blunt SS’s (almost 27mm internal). At first install they measured closer to 45mm, but stretched out over a couple of hours to right around 47-48mm. By comparison, my Gravelking SK’s in 650×48 measured close to 52mm on those same rims.

    • The 38mm measured true to size. 38.3 on a 20 internal rim and 38.5 on a 21 internal rim. Weight was 380 and 375 grams.

      Mounted up very easily. Held air overnight with NO sealant. With sealant they held the same air pressure for over a week. Very happy with these tires.

      My only wish is that they were a little lighter, closer to the Gravelking SK 38mm (which is actually a 40 on the same rims).

  2. The smooth center ridge seems significantly raised from the shoulder tread. While that should result in long wear life, I wonder what that does to the tire’s feel transitioning from straight to turning?

    • I’ve ridden the tire a lot and it feels a little iffy in those situations, especially on dirt. The sharp edge of the raised portion, combined with the skinny, but tall shoulder tread/knobs means you can feel all those tiny knobs squirm a little under you during cornering. The grip is there, but it’s un-nerving to feel that little bit of movement. For me, it’s more of an 80/20 road/dirt tire. I’ll take a 37mm Riddler, or a Byway instead.

  3. “In fact, they say it’s for rides when you’re rolling on road and off in roughly equal parts.”

    I wish we could just adopt existing industry standard language from motorcycle tires, and just call it a 60/40 (street/dirt), or 80/20, or 50/50, etc. Seems pretty straightforward.

    Sidenote: I like me gravel tires pretty aggressive. I wish SmallBlock8’s in 700×40 was a thing. or tubeless Knard’s.

    • Exactly, a little more pronounced, but basically the same tread pattern. Now…that’s not to say there is anything wrong with that tread pattern, as I have the Strada on my wife’s bike and they have been great for her 60/40 terrain. I do think the weight is an issue, but with the puncture layer and overall beef in the carcass, it’s just going to weigh more. No free lunches!
