Carrying Spare Tubes
 

Is it possible for a tube to develop a tiny hole on its own after being carried around in a backpack for about 2 years? The compartment I stored it in has no sharp objects.

Right now, I'm hoping that this was just a bad tube and have now learned to try pumping up the tube before mounting it on the wheel.

Tubes can degenerate over time, so yes, it is possible for a tube to "go bad." I keep the tube dusted with talc in a ziplock bag in my bike bag. I find the talc helps prevent the deterioration of the tube and the ziplock bag keeps it from getting dirty or contaminated.

+1. The talc also aids in mounting the tube in the tire when you do use it.

Biggest thing that will kill a tube is UV light, which isn't the problem for most people. From there it's the tube chafing against things or even itself in your bag.

I do as the two above me do, although i tend to carry two tubes, and a patch kit. What's an extra pound or two on my already heavy steel vintage touring bike.

Thanks for all the helpful suggestions.

Now, off to buy some spare tubes. :)

you telling me you went two years with no flats? Thats awesome

On my commuter bike I'd gone 2 years with no flats, until earlier this week.

I always wrap the valve stem with something, like maybe Saran Wrap.. I figure the threats about the stem might be a source of irritation and storing it within my bike wedge, there is likely vibration .

I keep one new spare tube in it's original box, and one patched tube in a ziplock bag. Good idea on the talc !

>2 years with no flats?

Yep.

The streets in Irvine and especially at UCI are pretty clear of glass/etc.
