I remember when GK was launched because I was on their Race Type A Evo tires at the time, and I recall that the GK was pitched as having an all-new construction— new casing, compound, everything— that was specifically designed for gravel use. It was certainly unlike any of the other tires they had at the time, as I recall; I had Paselas on one of my rigs, too.
Anyway, I’ve been running some type of GK since ‘16 or so, either in 28c or 32c tubed, and they’ve been great for my needs. The 28s were my gravel tires until I built up a dedicated gravel bike this year, and they were so well suited to the job that although I selected Herse rubber, I confidently stuck with the file tread type. I still use the 28c GK on my spring/rain/winter bike. Good tires, IMO.
