I have had good luck with Hutchinson's Fusion tubeless tires. They're not perfect (a tad heavy and they wear like a racing tire not a touring tire), but the performance is really nice in my experience. I haven't noticed any issues when removing and installing tires. The only slow leaks I've experiences come from valve issue or punctures. Thanks for your feedback!Jim Langleyhttps://www.blogger.com/profile/04184699406623972210noreply@blogger.comtag:blogger.com,1999:blog-6752457184418512360.post-26791655210406579322011-06-06T04:46:03.211-07:002011-06-06T04:46:03.211-07:00Hi, me again!

Update: I recently broke a spoke on the 6700 tubeless-ready wheel and was able to determine by looking into the spoke-hole on the rim that there is a cavity there which is sealed off from the outer part of the rim. Thus, the spoke-holes/nipples on this wheel do not need to be sealed/air-tight and they can let water in, but only into the internal cavity.<br /><br />I've just tested tire air leakage in the sink again, but this time only by dipping the tire (and not the spokes) into the water, one section at a time. No water ingress on this occasion!<br /><br />OTOH I think I shall be abandoning this road tubeless experiment pretty soon, as I have determined that the (Hutchinson-brand) tires always develop significant leaks through the casing once they've been removed from the wheel, even once!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6752457184418512360.post-48909492008330942282011-05-15T17:13:51.504-07:002011-05-15T17:13:51.504-07:00That's interesting.

We might need to cut an old rim in half to understand where the leak could be. But it shouldn't be able to get in on the tire side so it has to be the valve or the nipples you'd think - or some hard to spot hole in the rim. Maybe you can check for leaks without submerging the entire rim?Jim Langleyhttps://www.blogger.com/profile/04184699406623972210noreply@blogger.comtag:blogger.com,1999:blog-6752457184418512360.post-84353233118719516332011-05-15T10:33:13.183-07:002011-05-15T10:33:13.183-07:00I have Ultegra 6700 wheels with tubeless tires.

There's only one hole in these rims, which I taped over as you advise above. However, after I'd done my testing, I noticed that the rims were absolutely full of water sloshing about! I'm guessing that the spoke sockets aren't water-tight and that water was pouring in through these as I was testing? Anyway, I had to untape the hole and shake the wheel vigorously back and forth for ages to get all the water out!Anonymousnoreply@blogger.com
