Has anyone every thought about using timing belts instead of chain? Fitting it into a 2x1 box probably wouldn't be possible, but what about a 2x2 box. I'd imagine it would be even more of a "set it and forget it" scenario because a timing belt would be less likely to break than a chain.
That's a lot of weight you're gaining though (~2-4lbs depending on drivetrain), and you would have to settle for 1/8" wall probably. If teams say the chain doesn't break, then it doesn't break. That might be okay if you have the space and weight and mounting issues solved, because then you get a decent efficiency bonus.
