they're grippy, looks cool, and they're very light...
...but that lightness comes with a price. They're weak!
I was really happy to get these tires untill one of them exploded on me, out of nowhere! I wasn't even riding when BOOM! My rim (FRONT rim!) is brand new, I use a strong odyssey rim tape, my wheel is trued, brand new tube, 80 psi (out of 100 max), nothing sharp on the inside, nothing sharp cuttin through the tire... even so it exploded one day, and that made the tire useless! I think I'm gonna stick to steel beads.
