(DebW - I pm'd you on this too!)

I got a flat on my front tire. The tire actually had a small slash. Replaced the tire and tube. Pumped it up, went flat! No hole in the tube at all (slime tube, so I should see something leaking out, right?) Replaced it with another slime tube. Flat again! Replaced it with a regular specialized tube - yup - flat within five minutes!

I can't see any holes in the tube & I don't hear anything leaking out of the valve. I'm taking it to my LBS today.

My question - I'm REALLY apprehensive about riding tomorrow (27 mile race, flat & fast). If this thing keeps flatting, it could be very bad. Have you ever heard of this? If the LBS can fix it, do you recommend riding the 27 race?
