i hadn't noticed that. that's 23mm at 95psi in the front, 25mm at 95psi in the back ... i've been meaning to get it on a scale. i think larry has measured the weight, but i have not. it's definitely heavier than the vendetta - significantly heavier, but not so much that it would show in the wheels in that picture. i'm roughly 170lbs myself - maybe this was on the way back from the gas station after a burrito?
