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

Probably not as soft as the ultra high (320?) TPI open tubes, but they delaminate and the tread comes off when you use them overtake some serious miles on them. They're vulcanized, so it can't be. They are still reasonably comfortable and handle the MN's gravel turns well. They are also very light, which helps with climbing. I've probably ridden them 200 miles on gravel and another 150 on tarmac. Right now they are better in every way (as rough on MN gravel but not too sharp) than the MSO Clement they replaced. Flint skating can be different.
