I think your mechanism gets simpler, your gear loads and forces are more easily managed, and the chain takes all the abuse.

I've reread this about 10 times now.. I just can't visualize what you're saying. Are you suggesting having some loose chaing that is engaged and disengaged with sprockets? If you keep the gears engaged constantly.. how would you shift?
Thanks,

I think he means to move gear to chain, rather then gear to gear.
Have both final gears spinning, but rotate them to move the proper one into contact with the output chain. Puts all the meshing forces onto the chain.
At least, that is what I understood him to be saying.

Making and breaking chain with needlenose pliers is fun.
I swear.
