Tubeless has a noticeable performance advantage. You should definitely try it. Once you do you probably won't go back.I just don't like the idea of tubeless. For one, I heard it's not lighter at all (no idea if that is true or not), but most importantly, I hate the entire concept. Just the fact you can't let the bike sit for a while, otherwise you need to change the milk, which looks like a horrible mess of a job. I also heard the stuff leaks through the tires no matter what you do.
