The road sections between the dirt are where a lot of gravel tires bleed watts. Specialized built the Pathfinder TLR to hold speed across chip-seal, dry hardpack, and light gravel without dragging on the tarmac, and the reworked tread carries a claimed 19% rolling-resistance improvement over the previous Pathfinder Pro. If your rides trend toward compact surfaces with the occasional loose section, this is the tread in the Specialized gravel range that leans furthest toward speed.

The tread pairs two compounds: a firm GRIPTON T2 down the center for wear resistance and straight-line velocity, and a tackier GRIPTON T5 on the shoulder knobs for cornering grip. The low-profile center section and tightly spaced knobs keep rolling resistance in check on tarmac, while the shoulder knobs bite when you commit to a corner. Reviewers found the tire snappy and fast on tarmac and compact gravel, with the shoulders still supplying reassuring grip when the surface turns loose. It's a semi-slick approach that rewards riders who want to hold road-bike speeds until the dirt gets serious. The tradeoff shows up off-road: on coarse gravel and in the wet, testers noted the rear can slip under hard acceleration, so this is a tire that wants firm ground.

The casing is a 60 TPI 3-ply TLR construction, a shift from the older 120 TPI Pathfinder Pro layup. You trade some suppleness for a casing tuned to tubeless pressures and long gravel days, and Specialized pairs that with a claimed 25g weight reduction from the reworked, more open tread. The tubeless-ready bead lets you drop pressure for comfort and traction, and riders running these in the 30 to 40 psi range reported reliable, flat-free days over mixed terrain. Cut resistance is up 14% over the previous generation by Specialized's own figures.... Read More
