What size tube?

[Georgetown18]

My rubber band on my helmet broke today and instead of ordering one off of ebay or something I figured I would pick up a bike tire tube at walmart. The problem is that i dont know what size to get. I use a 1010 if that matters.

Go to truck tire repair shop. Ask them for an old truck tube. Cut said tube up. Easy. Free.

I've always used a "normal" car or truck size, like a 15 or so. Basically whatever is from the crap pile.

Depends on your head.

I have to use extra large.

Or check out your local bike shop. They always have old tubes lying around. I've found you can get 4 bands out of a std mtn bike tube (26").

I am a big fan of free too. If you can't find them, I have the Streamlight one for a whole $3.

Just make sure its not the fallopian type tube.
