Road Cycling - How do you use your old inner tubes?

I just opened a really tight jar lid by wrapping an inner tube around the lid. Best jar opener I ever used. Maybe I'm being a pack rat, but I save all my no-longer-usable tubes (i.e. more patch than tube). So, what are some other great uses for tubes that have passed their prime?

You can use'm to seal the seat-post tube when it's removed. Put a lenght of tube on
and fold it over. Secure with a rubber band.

I use a section of innertube as a Chainstay Protector on my MTB, stops all the damage from chainslap.
it's not a new idea but it's a good one.

Pedro's makes saddle bags out of them:

...the rubber goes all the way around the sides, making them durable. Pedro's is big into recycling and resourcefulness.

I use pieces of road bike tubes as covers for CO2 cartriges to keep them from rattling in my bags. I also cut a small piece to band a set of tire levers together so I can find them when I need them.

They do make excellent rubber bands. My pump sits under the crossbar. It rattles. But not when its got some inner tube bands around it. They also hold the old platic container for my repair kit shut. And they keep the repaired spare inner tube neat.

I use old tubes to hold the lid down on the outside rubbish bin...it fustrates the hell out of dogs!!!:D :D

Look at my username - put 2 and 2 together, and there's your answer ;)
