Glennwrote a review of Teravail Cannonball Tire - Tubeless on June 14, 2018
Familiarity: I've used it once or twice and have initial impressions
I have the 700x42 light and supple, running tubeless, orange sealant, specialized Hayfield wheels.
Just installed today and was very happy with how well they mounted. Completely dry with no sealant inside they took a quick shot from a compressor with the valve core removed. They held air just like that for a few hours. When I pulled the valve cores to add sealant they came off the bead slightly, but I was able to get them re-seated and inflated with a floor pump easily. The initial ride around the block a few times felt good, 40 psi and they rolled decent, pulled some sharp turns in gravel and dirt and they still felt solid. Going to put some miles on them and run the crusher race then will update my review.
