Review on 🚵 Challenge Gravel Grinder Race Tire 700x38C: Folding Clincher for Ultimate Performance and Durability in Vulcanized Nylon, 120TPI, in Sleek Black by Josh Elkins

Swapped out the Specialized 33mm OEM tires for the Crux and they greatly improved grip on fresh gravel climbs. We also had the opportunity to use them on some country roads where we encountered grass, mud, ruts, still water, sand and creeks. and in general they did well on all surfaces. They were a bit slippery in thick mud but much better than I expected and I had no problem scaling them. I am currently using them with flat latex tubes on the inside which seems like a good combination. Overall I am happy with these tires and would buy them again.
