They are a little harder to mount, but the ride is very nice -- similar to tubular. You can run then at a lower pressure -- for my weight, that's 100 PSI rather that 110-120. The weight of the tubless is about the same as a normal tire and tube.
Thanks for the info. I guess this is the future of tire technology. The convenience of clincher with the smoothness of tubular. I didn't realize that the tubeless setup would weigh the same as a clincher and tube. Anyway, be sure to post a full report once you get some miles on them.
