    Holes in inner tube at folds

    I keep a spare tube in the seat pouch. But, after a few months they tend to develop holes at the folds. There aren't any sharp objects in there to puncture the tube. So, should I guess that it's from contact with the inside of the pouch?

    Was wondering if anyone else has experienced this issue? If so, what corrective steps did you take?

    Thanks.

    You are most likely correct that it's from rubbing on the pouch. You could put a old sock over it ,or wrap it in a rag ,figure out a way to secure it in the pouch.

    Old sock sounds like good advice. Perhaps a polyester sock will be more durable than cotton.

    Had this happen to me and I don't use a seatbag but a strap. I think mine were from folding it too tightly and just UV/age.

    yep

    have a polyester, or 50/50 poly sock ?

    keep cap on valve, fold up tube, stick tube in sock, then store that

    sock should keep tube from wearing at edges. mine last forever stored like that, no odd wear or blown tubes

    I just checked my spare tube I keep on the road bike. Its been folded very tightly (never inflated, right out of the box) with a rubber band on it, stuffed between the seat rails for 3 years. Holds air perfectly!

    Its so old that I forgot I went to deeper rims, so it doesnt even fit the bike. Glad I checked! Tubes should hold up fine if kept somewhere they're not rubbing. A few months is way too short!

    Neat trick: Vac-pac your spare tube! Sucks ALL the air out so it packs much smaller, AND the package will take this kind of rub abuse rather than the tube itself.

    Win Win!
