I’ve used these for racing for several years as they are very fast and have great feel and grip for criteriums and time trials. The trade off is they do wear out fast and don’t have a lot of puncture resistance so they are race only tires.

These are great on your training wheels or for competitive cycling. Aired up they've got minimal resistance. The old school file tread grips like the last of the early 80s Clements. Why go tubeless when you can still roll on tubulars like these?
