Familiarity: I've put it through the wringer
I have used these tires for gravel races as well as my weekend road training rides-- typically around 40 miles long. I think they roll really well on the pavement, especially for how durable they are. Off road, I find they have good volume for comfort and surprising grip on fast fire road descents. I am most pleased with their durability. I had a road tubeless tires on before (pavement only of course) that punctured on seemingly every long ride. I have had these on for about 1,200 miles without a single puncture. I will definitely buy again.
