Vintage speed tire question

[David Luciani]

tubes can take ALOT of abuse sometimes.
few years back i installed a tube with not enough talc and no air.
sure enough i pinched the tube.
i didn't find the problem till i unloaded at barnsville.
the tire had held the air just fine but about an inch was visible along the seam of my margay rim..
i had left the spares box with tubes home to reduce my track package so i asked around and nobody had a spare tube. rather than find out the tube was ruined i just watched the air pressure that whole weekend.
held fine.
i'm not great at keeping track notes and forgot about the tube.
couple times i noticed the issue watched the air and promptly forgot before i got home.
at rigp my first year i missed the first race because of a stall .
then second race i lost my chain second lap.
i discovered a flat tire had let the sprocket bang the pavement and derailed my chain.
turned out it was the same pinched tube i'd basically ignored for almost four years.

so i learned tubes can take alot of abuse but i don't advise doing that extreme an experiment!!!
