Default Re: A new shift concept for the engineers....

I was aware of the jackshaft systems that are available. My thinking was that most of the jackshaft systems end up kind of messy looking on the right side, and using the crank hub would clean that up. The drawback is trying to get a 15-1 gear reduction on the left side, and keep it clean looking. Probably just need a decent chain guard design.
