On a geek note, I finally got a flat in a Hutchinson Fusion tubeless last night. I can report that after two and a half years the latex (Stan's) was not dried up at all and tried its best to fill the huge cut resulting from running over a piece of glass apparently lying long-ways in the road. I had read that the latex would dry out after a year or so, but not in this case. Just thought a couple of you might like to know that.
