Underneath the touring-style shallow tread there's a Kevlar breaker strip. This wasn't as tough to penetrate as the tread of the Krylion, but was the equal of most of the 700Cs. The skinwall sidewalls are fairly easy to pierce. Weight isn't bad for a wire-bead tyre, and only the Conti Gatorskin matches it on value in this test.
It's available in a large range of sizes, and in the larger widths should be able to handle rougher surfaces better than the full-bore slicks. I'd prefer the more expensive Panaracer Urban Max, which has a 'hypertex' casing to add sidewall protection, but for the money this is as good.
