After reading several glowing reports of this tire, I bought a pair for use on an upcoming 120 mile gravel event, which includes rocky, challenging, terrain. Initial setup went OK, except the casing is porous, and sealing with Stan's liquid was not great, even with vigorous shaking and extended time left on their sides atop a bucket. Next time, I'll use Orange Seal.
The casing is supple, and after some pressure experimentation, I found the ride comfort to be quite fine. Climbing and cornering grip is good, though not much better than some other 40c tires I've used.
Rolling resistance seems higher than 40c Nanoraptors, regardless of the psi used. Other reviews have said these tires roll well. Wish I could agree, but that wasn't my experience. I will try them again to confirm, but initially, I'd say the Nanoraptor is faster rolling with comparable grip.
