Re: A new shift concept for the engineers....
We can call it the Fireball... I guess.
As far as the free wheel goes I never ride in reverse so I don't think that would be a problem. You could also offer different gear set ups, because I would want something with a larger sprocket for hauling fat guys up hill, as opposed to trying to break the sound barrier.
As far as as a 410 size goes that should still work for those of us that run a 415 as long as that is taken into consideration, because the pitch is the same just a bit wider right?
