Money has nothing to do with it. I have bought plenty of over-priced crap in my time (anything made by Spinergy for example) and have no trouble admitting it to myself.

Rolling resistance occurs partially due to the friction between the tire and the tube, and by eliminating the tube, rolling resistance decreases. How much? I have no idea, but that is not why I bought them.

I just like the way they ride, and in that case, perception is everything. Also, without tubes, no pinch flats. Also, you can use tubes and other tires, and they are very good wheels used that way as well.

Tubeless Road Tires are a new enough product that there isn't much real-world data just yet. Nothing that the marketing department hasn't tampered with, at any rate.

So all we have to go on at the present time is anecdotal reviews of people who now swear by Tubeless tires. I suppose if I dropped $900-$1400 on a new product, I'd want it to be everything I'd hoped for, too.

But on the issue of rolling resistance, the best info I've found comes from Jobst Brandt:
