CX/Gravel Tire Test: Teravail Cannonball Light & Supple 42

Teravail is a relatively new brand that offers a wide range of off-road tires that ranges from gravel bike tires all the way up to fat bike tires. The Cannonball is their most all-round gravel bike tire, and it's a good place to start testing Teravail tires and see how they perform in our tests.

With Teravail being a relatively new tire brand, it's always exciting to see if we've found a "special" tire brand that can outperform the competition. With the Teravail brand, our hopes aren't that high as it doesn't look like they've done much research into compounds or casings. Their main effort seems to have gone into tread patterns for off-road tires. Unfortunately though, the tread pattern isn't something that makes a huge difference in our tests.

Teravail also seems to specialize in making their tires available in a huge range of different sizes. Every type and size is also available in a version with black sidewalls and a version with tan sidewalls. On top of that, you can pick any size and sidewall color in their "Endurance" casing that offers more protection or their "Light & Supple" casing that's lighter and faster.

This is a test of the 42-622 Teravail Cannonball with black sidewalls and the Light & Supple casing.

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

The Teravail Cannonball is an average performer in nearly all of our tests. The main weakness and the potential deal-breaker is the puncture resistance of the sidewalls, which may be a bit too low for a tubeless-ready gravel bike tire. As the sidewalls are much thinner than the tread, the tubeless sealant will have a tough time re-sealing a somewhat bigger puncture or cut and will leave you stranded.

As most people looking for Teravail tires probably aren't going to use them for racing, it might be wise to simply go for the Endurance casing as it should up the protection level to adequate levels and also make it a more durable tire in the long run.
