Supposedly the newer GRID casing (as the Slaughter would have) is quite a bit burlier than the old stuff. If I recall correctly it's more like the SX casing they used to do, but with a tubeless bead.This is very interesting to know... I'm very curious about the tire. Question about casing: is Grid like Maxxis EXO, or is more heavy duty? I'd like to give this tire a try, and would like to go lighter than the DH casing, but my past experience with Grid was about 5 years ago, and back then, it wasn't much heavier duty than Control casing - it was just lighter.
The problem here is that shops don't carry the tires, you have to special order them, so you can't pick them up and compare and contrast in person...
