There are two popular models of Maxxis tires (at least for the road). The detonators come in colors while the refuse do not. The detonators lack the kevlar belt that the refuse has. While I generaly felt the ride of the detonators were nicer than the refuse, the lack of flats on the refuse wins out. Even when I had a a lot of missing rubber after like six months of a refuse on the rear, it still didn't get a flat. I only got a flat with the detonators when I put a hole through the tire.
