I have a Challenge Grifo that has a slow leak -- in Saturday's race it dropped from 38 lbs to about 20 over the last two laps (I nailed some roots pretty good, bottoming out on the rim), eventually costing me 3 places because I had to tiptoe through the corners. I'd squirted some Slime in it a couple weeks ago, and it holds air fine when not being ridden on. After Saturday's debacle, I pumped it up to 50 psi, and it stayed there overnight. Should I put some more Slime/liquid latex combo in there, should I give up racing on it, or should I send it to that guy in Florida that fixes tubies?

buy a new one and send it to the guy. that way you have an extra the next time you flat one.

Put more sealant in it and use it for practice.
