They have 20 some pins in the tire.

The ride is hard to describe. They seem to move immediately when you stand up to accelerate==like a say crono evo at 200 psi. When rolling along sort of like any mid range clincher at 100-110 psi. Over bimps more like the crono evo at 200 psi.

IMHO great trainer tire, acceptable for training, even in groups. They would make a great commuter tire.

And for a disabled racer who can't change a flat after a stroke--perfect training tire.
