Re: A new shift concept for the engineers....
Actually the idea behind the thread was to come up with an inexpensive way to easily change gear ratios. Before I totaled my bike and before winter hit I was actually running with two rear left side sprockets, the problem was chain tension. Switching from one sprocket to the next required to much chain for my tensioner to absorb. And my original thought was if some body came up with a decent spring load tensioner similar to the right side derailer than you killed two birds with one stone, minor shifting capabilities and the elusive chain tensioner grail. But then we got side tracked by internal hubs and jackshaft kits.
