Also the cool thing with a 3 stage ball shifter gearbox is that the third stage actually isn't "part" of the gearbox the way it's assembled makes it fairly easy to mount the gearbox. Additionally given the good track record vex parts have had I don't expect much maintenance ever to be needed, only in worst case scenarios which can't be avoided.

Cool design! When our grade11 students showed me their preseason drive train, I envisioned something like this, but they were reluctant to hide the chain, and probably for good reason. Repairs if something goes wrong with the chain would be difficult. Also, I would be wary of using these wheels in a drivetrain, especially one like this where replacing them would be a bit of a challenge. We ordered some samples, and they are tiny! The narrow width means the tread will wear pretty quickly.
