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

Here is another angle to attack the shifting from. Instead of copying the rear derailer for shifting, why not copy the front derailer, less moving parts, and I imagine it would hold up a lot better, and then make a separate spring loaded tensioner piece. Not to mention that most motor bike chains on the left side are above the chain stays not below it making the rear derailer useless...
