I just ran a pair on my 2017 Roubaix. I wore out the back tire in 1,200 miles, and after another 900 miles both were pretty chewed up, due to the roads I ride. But, no flats, no issues. and they ride and handle very well. While not as smooth or easy rolling as "race" tires like the GP 4000s or GP 5000, they are not slow by any means. If you need a tire that's more durable than those pure race tires, it's a really good choice.
