My second pair of Gravelking SKs and they are great. Set up easily and give me confidence on a variety of dirt and gravel.
I've been using these in 35c for pretty much everything for the last year, from commuting about 20 miles each way in DC, to the full 120-mile unPAved gravel race last October, to gravel on the C&O canal trail, to dry cyclocross races. They set up tubeless super easy, with hardly any leak-down and zero burps. They're more supple than I expected, but I have not had a flat as of yet. The grip is superb on pretty much everything but the really chunky gravel. With a couple thousand miles on them the rear knobs are about worn down, so here soon I'll be replacing the rear with a 43. Highly recommend.
I've been running these in size 700x35 on an SSCX-type bike as a commuter in NYC for a good few years now, and they've proven themselves in all weathers. Lightweight, fast on dry pavement, insanely good at shedding water and mud, and just enough tread depth to keep the tiny shards of glass and metal found on city streets well away from my tubes. I won't go back to slick tires for my commuter, there's just no reason to. The Olive Green colour from 2020 was perfect, Panaracer ought to reissue it.
