Just a quick post on this topic. I recently decided to try tubeless tires on the strength of good reviews on Hutchinson's Fusion 3s (and out of curiosity). I don't have tubeless compatible wheels so I had to convert.
Road.cc had a good piece on this but I could find little else online about what sounded like a daunting prospect - so I decided to write about the process as a little how to. You can read about it here: http://theinquisition.eu/wordpress/2010/06/road-tubeless/
Anyway, I hope this will help if you are curious about what it takes to do. Its actually quite easy.
