Fresh Gravel: Teravail Cannonball 38mm Tires

<Back to News Home |


Teravail Cannonball 38mm tires are the “Official Tire of the Dirty Kanza 200”

Fresh Gravel: Teravail Cannonball 38mm Tires: has just purchased a set of Cannonball tires to give you all some impressions on this new design from the new tire brand dubbed “Teravail”. You can see more about this brand in our earlier post on Teravail which includes more news about different models and specs for each here.

The tires had a soft introduction at last Spring’s Dirty Kanza 200 where they were shown on a few Salsa Cycles bikes which were on display there. We learned at that time that Teravail was about to introduce the first tire specifically designed for gravel use, the Cannonball, and that this tire would also be a tubeless ready type tire. The story we got was that gravel, which is often loose and deep across the roadway, can be difficult for a tire to negotiate, which causes “squirming”, and this results in higher rolling resistance and less stability. The designers of the Teravail Cannonball claimed that this new tread design lessens rolling resistance and increases stability for a better riding experience on gravel roads. Obviously, the tubeless nature of these tires will lessen the chances for flat tires, but this should also increase rider comfort and control.

Our samples weighed in at 500 grams and 510 grams respectively, right on the money for what Teravail is claiming for weight on these. Trying out the Cannonball on an American Classic Argent wheel, we found a snug, but not impossible to mount by hand fit. The tire aired up easily. Our next post will give more details on this tire, so stay tuned. We have a new test bike in for review which these tires should be perfect on. Look for the introduction of that bike which should follow this post directly.

Note: Teravail did not bribe or pay for this review and these tires were purchased directly by for test/review. We will always strive to give our honest thoughts and views throughout this review.

    Wondering how well these hold up to pavement use. 15-20% of my gravel routes are on pavement to transfer to the next gravel road. The Clements I have aren’t handling this very well at all. Really curious about the cannonball.

      Which Clements are you using? I’m running Clement USH tires with around a 50/50 pavement to gravel / trail and mine have held up fine thus far.

      Some of the testing will include pavement and dirt, so we’ll keep a close eye on tire wear.

      I LOVED my Clement LAS tires, but they wore extremely fast when pavement was involved…I think I could get about 800 miles on a rear tire before it became a semi-slick down the center and thin enough to be highly prone to flats. On average my gravel rides are 50/50 paved/unpaved (wish it was higher…)

      Very much looking forward to the tubeless MSOs…a friend has the 40mm version and gets thousands of miles out of them, and he puts way more road miles on them than gravel.

    My dealer has the Teravail 38 and thinking about switching to them for my gravel riding. Currently on Schwalbe slicks in a 35. They have performed well for over 600 miles of gravel on my Warbird but want to move to a tubeless with a little more air volume. Also believe Clement is coming out with a tubeless in the MSO soon.
