I'm sick of changing tubes. Popped the original tube in my 500 in the first ride. super thin! when to swap in the one out of my CRF and because I left all my tools on the job site and had to "improvise," it did not go well, I tore that one open also.... needless to say im sick of tubes. I've look at other options, including the balls, the tubeless system and the super heavy duty tube. they all have their ups and downs but the one I like the most is the Michelin Bib Mouse Tube. One question I have is they list that you MUST use them with Michelin tires, is they a ploy to get you buy their tires as well or is there real problems with running something else?
