Can I use a wheel with a tubeless tire for long-distance riding? I mean, whats the worst that could happen, right? Ive seen all these roadies singing the praises of tubeless tires, but arent they just asking for trouble on a long ride? Dont they worry about getting a flat and being stuck with no tube to boot? I know some of the mountain bike crowd swears by tubeless, but thats a whole different ball game - were talking rugged trails and short distances, not smooth roads and marathon riding. And what about the whole sealant thing - isnt that just a fancy way of saying cement thats going to dry up and leave me stranded? Im not trying to be a skeptic, but I genuinely dont get why anyone would trust a tubeless tire for long-distance riding. Am I just missing something, or are tubeless tires just a recipe for disaster on a long ride?
