The pumpless pump
Your tires nearly flat?
But that other bike over there seems to have plenty?
No problem, just borrow some air ...

But one will be higher than it was!!
If one bike has 30 psi and the other 120 psi, then they will both leave with 75 psi.

Not to hyjack this thread but how often do you exchange the old air in your tires for new air. Will it help to run straight nitrogen?
Do you rotate the tires on your bike........Front to rear or side to side?

If you have a 30 psi tire and your newfound "friend" has two tires at 120 psi. Then you get up to 75 psi from the front tire, and then boost it to over 90 psi off of the rear tire.
I'm sure CrossChain or Big Paulie wouldn't mind!

I think that my screw on valve and CO2 cartridge is reasonably light and pumpless.

But your CO2 is much more costly than free air.

Air is only free if your stealing it from some poor unsuspecting bicyclist. Else you have to work for it.

How do you think the tourists are going to feel. "Hey....I went up to Minnisota to meet some of the nice people and some Guy in a winged helmet stole the very air out of my tires". Geesh, you'd think it was New York.
