CX/Gravel Tire Test: Specialized Pathfinder Pro 2Bliss Ready 47

The Specialized Pathfinder Pro 2Bliss Ready is a tubeless-ready gravel bike tire made for a mix of asphalt and gravel roads. The Pathfinder Pro has a remarkable tread pattern that we expect to work well in most gravel bike conditions as it comes with a slick center tread, small, closely spaced knobs between the center and edge of the tire, and larger and wider spaced knobs along the edge.

We already tested both the 38 mm and 42 mm versions of the Pathfinder Pro and found them to be strong performers in our tests. The strong performance comes from Specialized's Gripton compound, which offers a low rolling resistance and excellent performance in our wet grip test. The BlackBelt anti-puncture strip under the center of the tread is quite rare for a gravel bike tire, but it works well to prevent punctures.

On paper, all sizes of the Specialized Pathfinder Pro are created equally except for the obvious size differences. We'll compare the 47 mm version of the Pathfinder Pro against the 38 and 42 mm versions, which will give another good indication of how gravel bike tires perform in different sizes.

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.

Conclusion

When it comes to rolling resistance, the biggest version of the Specialized Pathfinder Pro falls right in between the 38 and 42 mm sizes. We're unsure if we can draw actual conclusions about the rolling resistance based on our samples. From the looks of it, and because our samples are from 2021, 2022, and 2024, we suspect there to be a manufacturing tolerance, as the numbers just don't seem to make sense.

We see a clear pattern in the wet grip tests where the larger sizes offer better grip than the smaller ones, which makes sense and is in line with what we've seen with other tires. All other measurements fall within the margin of error of our tests.

It looks like compound mixing is the most critical for rolling resistance.

RATING: 4.0 / 5
TEST VERDICT: Highly Recommended
