Double Tubing: The Third & Final Update

Just pump up just one tube and carry a pump. *When you top off once
every 2 weeks or, in my case, every 2 months, alternate between
tubes. *Deflate the tube that you were riding on and inflate the
other
tube. *This eliminates the hassle of getting the same volume in both
tubes and provides a check so you can always be sure when you take
off
in the morning that you have two good tubes.- Hide quoted text -

What do you do about two valves as there is only a hole for one?

Bret said previously that he drills another hole 180 degrees to the standard
hole.

It's so easy that it's more of a practice than an invention.
