Great on any dry surface

Wet surfaces

Pretty sweet tires. I won them at a race and they hold up pretty well. On dry, fast or technical courses these tires are the bomb. Also, the 45 psi minimum is great! (I run them at 35 psi and have not flatted yet) Little rolling resistance and the side knobs bite into the ground quite well. However, on slick grass or mud sliding out is a slight problem, there are much better tires for wet races. But in the dry they are great and so far very durable.
