This is something that I have been contemplating for a while.

I haven't figured out how to get this to work in both directions, but if you had a 3 cim gearbox and one of the cims was geared significanlty lower, lets say 3 times lower, and was connected using a one way locking bearing would there be any significant gain in acceleration? Is there any reason for doing this instead of a 2 speed gearbox?

Thanks again
