I mounted these tubeless and have to ride on my gravel bike. I was surprised how light they are and how durable.
We rode them on two bikes down the Rallarvegen in Norway that is 30
Miles with, seemingly, 20 miles of rock gardens. Not a single problem and they worked great.
Also, when riding them on my normal road bike routes, I was surprised at how fast they were - did not feel at all like a gravel tire. Theyre very supple and five a plush ride.
So Im a big fan of these tires. Do set them up tubeless (which is what they were designed for). Riding them with tubes covers up much of what makes these such a great tire.
All that said, I would not say they are a tire you should expect to excel at durability over distance. The compounds that make them corner so well and be supple also mean they are not going to be the longest wearing. For me, thats a trade off Im willing to make every day and twice on Sunday.
I love the way these tires ride. Some of the best I have ridden on my mostly pavement commute. My only complaint is that the rear tire wore out quicker than many tires I have used in the past.
I love how light and smooth these tires are on pavement, and they were pretty good on steep big-rock gravel roads in the Hell's Canyon area. No flats, which was amazing. In spite of biggish rocks, did not bottom out or hit rock to rim even once in about 30-40 miles.Tread material is soft and not too durable - with only 500 miles, little bumps were gone from rear tire and center of front tire. After gravel experience, several visible cord spots (12-dime size) lead me to believe this tire really isn't made for gravel.

While expensive, I love these tires. I put them on a super stiff cross bike I have that I want to use for credit card touring. I set them up tubeless. Imagine my surprise when the ride was uber plush, my average speed was right up there with my road bike, and they gripped and carved their way though turns.
If you look at these tires, they are really light for the size - not much different than a tubular tire. Set up tubeless they are supple and comfortable and handle well. Set up with tubes in them, they feel like they have sidewalls made of hard plastic and the ride is truck-like.
So far, I have about 700 miles on them and the center slight knobs are worn down (I'm not a light rider). So I think they will last a little bit less than other tires might. But the ride quality is worth it if that's the price I have to pay for what I get out of these tires.
I think Schwalbe has done some good work here. They seem to hold up and I haven't had any punctures despite riding over some nasty stuff. I'm happy to recommend these, but set them up tubeless.
3-Star Disclaimer I attempted to run these on a winter commuter (adventure) bike. They are NOT suited for commuting on the terribly maintained shoulders in the Portland metro area. In 800 miles I had 9 flats, both tires have several significant cuts (two that require a boot), and the tread on the rear tire is already squaring off. I would have some doubts about these as gravel tires seeing as how poorly they fared, but it could just be that they don't get along with glass at all. And that I've had a run of really bad luck too.
They are very comfortable, grippy and predictable (wet and dry), surprisingly lightweight, and roll fast. I think if you just want a fast comfy tire that you could take on trailsunpaved roads they'd be pretty dang good. But if you're looking for something tough and long-lasting, I'd look elsewhere.
