We are a heavier team at 450# all in and ride Conti Gatorskins in 28 at 110psi and 32 at 100psi, this is under max on the 28 and just over max on the 32. We had our first flat for couple of years recently which was a pinch-flat on the rear. We hit a patch of gravel on a decent and flatted quickly, not catastrophically it just went down quickly. We've been very happy with these tire, I know other tires have better "performance" but these have treated us very well over the past number of years.
