CX/Gravel Tire Test: Michelin Power Gravel 35

Michelin has been making some of the most popular and best performing road bike tires for a long time so we couldn't leave them out of the CX/Gravel section. The Power Gravel is currently their only tire in the CX/Gravel category but as it comes in the 33-622, 35-622, and 40-622 sizes, they cover a wide range of use cases from CX to gravel bikes.

The Power Gravel is made up of a 3x120 TPI tubeless-ready casing with an extra layer of "Protek" puncture resistance material that runs from bead to bead. We really like CX/Gravel tires with reinforced sidewalls (+1) as this helps protect against cuts especially when used tubeless. The compound is Michelin's X-miles compound that is optimized to last a long time yet still has a decent rolling resistance and grip.

We've tested the 35-622 version as that is the perfect size for our mixed CX/Gravel category.

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

We feel the Michelin Power Gravel is an excellent compromise between speed, protection, tire thickness, and knob height for a CX/Gravel tire. Rolling resistance is a bit higher when compared to the fastest CX/Gravel tires but you'll get better protection and knob height in return. We would be surprised if you had something to complain about with these tires.

If you've had troubles with cuts and punctures with other tires, the Power Gravel might be worth a try if you don't want to go all out on the most puncture-resistant CX/Gravel bike tires. Go to the CX/Gravel overview to compare against the other tires.

RATING: 4.5 / 5
TEST VERDICT: Highly Recommended
