The Teravail Cannonball Tubeless Gravel Tire was designed to be a first-choice gravel racing tire. The directional, tight-knit center tread efficiently sheds dirt and debris to decrease rolling resistance, while the side knobs provide effective cornering traction. This Durable sidewall version is constructed with a robust woven nylon composite reinforcement between the outer rubber and the inner casing within the tire’s sidewalls to prevent tearing and abrasions.


  • Designed and inspired by experiences seeking the ideal all-terrain, all-weather tread pattern for gravel and adventure cycling.
  • Durable sidewall prevents tearing and abrasions for extra flat protection. 
  • Tubeless ready for flat prevention, lower-pressure traction and comfort
  • Ideal rim width of 23mm

Teravail Cannonball Tubeless Gravel Tire (Black) (700c / 622 ISO) (35mm)
Put these on a Giant Revolt. I do combo mileage of crushed gravel, packed dirt and street riding. Pros: Increased my street speed easily by 2mph as they are way less resistant than the original 40mm tires that came w/ the bike. Decent traction on trails and good absorption on crushed gravel. More nimble on trails. Cons: Not great cornering on pavement- tail end has come out from underneath me when cornering at higher speeds. Not as great a bite in loose dirt/gravel also. Realizing that no tire is going to be great at all things, this is a decent all around tire that serves me well on streets and trails. Did a NYC to PHL ride last week of combo city streets and D&R trail- all dry. Short of above, served me well and a good compromise for the riding I do.
