Tubeless ready tires tend to be heavier than there non-tubeless counterparts. By design you wouldn't be using a tube either (the tube would make up most, if not all, of the weight penalty anyway), so the weight difference between the Cannonball and the Challenge Gravel Grinder is sort of a moot point.
On the whole, this company is making some interesting tires. I'm digging the Lickskillet and the Cannonball.
