Michelin Power Gravel (v2) 40 road bike tire on a rolling resistance test machine

We already tested the 35 mm version of the Michelin Power Gravel back in 2020 and found it to be quite a strong performer in our tests. Michelin recently released a "v2" version of the Power Gravel that comes with some undisclosed changes that we're hoping to make more apparent. We've tested the 40 mm version of the Power Gravel, making it harder to compare it to the 35 mm "v1" Power Gravel.

We've taken a long look at the (limited) specifications of the current Power Gravel (v2) lineup, and one of the few changes we noticed is that the specified weight of the 35-622 version (read our review) has gone up from 380 grams for the "v1" version to 405 grams for the current version. Even though our 2020 sample of the Power Gravel 35-622 already came in at 412 grams, it might indicate the tire has been made a bit beefier somewhere.


Wehen mounting the tire, we also noticed that the bead circumference has increased as the 35-622 "v1" version we have here fits extremely tight around the rim (we heard this from some others as well). The 40-622 went over the rim edge much easier, and it might indicate that the "v2" version has been modified in this area.


The Power Gravel is available in the 33-622, 35-622, 40-622, and 47-622 sizes. On top of that, the 47-622 is also available in a version with light colored sidewalls.


Let's look at our test results of the 40-622 "v2" version and compare it to the 2020 35-622 "v1" Power Gravel to see if we can spot some other changes.

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.

When we compare the "v2" Power Gravel 40-622 to the "v1" Power Gravel 35-622, our test results show that the 40-622 version performs better in the puncture tests, but rolling resistance has gone up. There is also a slight difference in the knob height in the center of the tire, where we see knob height has gone up to 1.5 mm from 1.2 mm.


Unfortunately, we didn't compare the "v1", and "v2" versions of the Power Gravel in the same size. It might be possible these differences must be attributed to the change in tire size instead of the specific tire version.


When we compare the latest 40-622 version of the Power Gravel to the competition, we're a little less excited about the Power Gravel. We've tested a lot of other CX/Gravel bike tires since the test of the original Power Gravel back in 2020 and have found some other tires to perform a bit stronger.
