I've got the option to get a set of the Ultegra 6700 tubeless wheels for a pretty good price but saw a lot of mixed reviews of actually using them tubeless for cross due to problems with burping, etc. But the new Hutchinsons are (in theory) more secure due to the carbon bead. Anyone have experiences, positive or negative?
I am waiting on my hutchinson piranha's to get here. I am going with Stan's cyclocross kit using Ksyrium Elite wheels. A team mate of mine uses the dura ace tubeless and has pretty good luck with them so far.
I am running the Hutchinson Piranhas on this exact wheelset and they do work pretty well. My only issue is that after a race and some CX practices they were out of true pretty bad. Bad enough that I could turn the spoke nipple by hand. Otherwise, they are great. I usually race on tubies and train on these, but I did have to race them once. Not as good as tubies, but way better than standard clinchers.
