I've heard of people with custom frame setups that allow them to store liquid (fuel) in their bike frame (Mike C's Iditarod bike, among others). A neat idea I'd like to see/hear more about.
Then I saw this coming from King Cage on bikerumor's site:

The $200 titanium 'Whiskey Bar.' Guessing one could use it for fuel storage- and no custom fabrication needed.
Seems like it might be a bit of a pain in actual use, but would certainly free up some space. Anyone doing this currently with custom bars? Any thoughts?
