I have Mavic cosmic pro ust wheels. I’m running specialized Roubaix tires. They were a ***** to get on and I’m not looking forward to a flat in the field. Before the flames start for not running tubeless, I got these wheels because I got a crazy good deal on them, not because I wanted tubeless. If you try different tires, I’d buy them from a shop and watch while they mount them so you won’t have to buy them if it isn’t a reasonable fit. If you try to mount them yourself, the won’t let you return them.
