I just tested these out today at sectionals, (I know, kinda risky, but it paid off.) I have to say these tires RULE!!!!
Obviously, they are a race only tire, as they have next to no puncture resistence, but at 160g each in 23 by 700C they are the bomb! They accelerate super quick, and the ride! OHHHH the ride! The closest thing to tubulars in a clincher. The minimum pressure for them is 130PSI!! Max 160PSI!!! I couldn't beleive how fast they roll! Like I was floating over the pavement!
They do it all, corner, remain supple, roll super fast and weigh next to nothing.
If anyone is looking for a badass race tire, fork out $100 for a set, and get the best!
Just don't use them on a everyday bike, RACE ONLY!!! they are thin as paper!
