According to Specialized, the S-Works version of the Pathfinder is even faster than the Pathfinder Pro (read our review) that we tested a while back. The Pathfinder S-Works comes with the same tread pattern (with lower knobs) and the same casing with BlackBelt anti-puncture layer under the tread. What's different is the GRID RACE sidewall reinforcement and an upgraded T5/T7 Gripton dual compound.


The main improvement over the Pathfinder Pro is found in the weight department, as we found the Pathfinder Pro to be quite a heavy tire for its size. The S-Works version shaves off a massive 105 grams per tire for the same tire size, making it more competitive with other tires and more suitable for those who care about weight.


Unlike the Pathfinder Pro, which is available in a couple of different sizes, the S-Works version of the Pathfinder is only available in the 42-622 size. That's probably not a big issue for most but something to be aware of.


We've run the S-Works version of the Pathfinder through all our tests, including the wet grip tests. We're still re-testing wet grip of all CX/Gravel tires, and we'll add the data to the database when we've done a batch of tests, but it's going to take some time to test all 44 CX/Gravel tires. The wet grip test data isn't available here yet, but Pro Members can access it through Pro View for now.

The CX/Gravel section is a multi tire size section, air pressures have been adjusted to the measured casing width.

All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs.

Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load.

Even though we've only tested wet grip of 17 out of 44 CX/Gravel tires up to now, it's already evident the Gripton compound offers tons of (wet) grip. Both the Pathfinder Pro, Pathfinder S-Works, and the Roubaix Pro, which all come with some form of the Gripton compound, offer outstanding grip in our test. We'll test wet grip of more CX/Gravel tires soon (available through Pro View for now), but we don't expect many tires to get up to the level of the Gripton compound tires.


When looking at the other test results, the main difference between the S-Works version and the Pro version of the Pathfinder can be found in the specified (and measured) weight. The weight reduction comes from the halving of the knob height from 2.0 - 2.4 mm to 1.0 - 1.2 mm and reducing the compound "fill" on the sidewalls.


We can't confirm the claimed reduction in rolling resistance, but it's probably as good as it gets with a compound that grips this well. The weight reduction will give a performance boost, and we would prefer the S-Works version over the Pro version any day for the slight price increase.


RATING: 5.0 / 5
TEST VERDICT:
Highly Recommended
