I just glued a set of Conti sprinters.
Pumped em up and hung them to set.
I noticed later (about 3 hours) that one of them
was flat. So, I've got this unridden, glued tire.
Any suggestions other than just repair it?
I'm not sure where its leaking from, no noticable
hissing, or bubbling when I wet it.
I don't think the presta valve is leaking but will test
that again when I get home.
I'm kind of stumped here.

thanks,
Marty

The last set of Sprinters I bought were a mixed bag, one being decent, and the other being rather haphazardly assembled. Sometimes cheap tubulars have punctures in the tube, due to some nincompoop at the factory running the sewing needle straight through it. Maybe Sprinter quality has sunk to that level, too?
Another thing to check: is the valve core fully screwed in? sprinters are one of the few tyres still having removable valve cores.
