Erm, from memory I think so, been a few years since I used them, and vowed to never again, bitch to fit, and quite easily punctured, but that was when they first came out, and 32mm. Eventually I gave up and went back to Paselas.
For what it's worth, I've used Paselas (in 28c) and Gravel kings (in 32c) and liked them both. I've done about 2000km on the GKs so far and not had a single puncture. I think I've been fairly lucky though.
