Definitely too tight to pull the bottle out while riding; I actually have to stop, get off, stand behind the bike, and hold the cage with one hand while pulling the bottle straight out with the other.
It takes me two hands to install / remove the bottle that launched itself on a relatively small bump. I don't think they would go anywhere when I'm in the saddle, because my weight damps the road shock, but when I get out of the saddle for a bigger bump, that whole seat tube / carbon seatpost / arm makes a pretty good launch spring.
Bob, what types of bottles are you using?
I'll try the rubber band thing, and maybe create something out of an old inner tube.
