Re: A new shift concept for the engineers....
I had the same thought. But everything on the right hs to be reversed. So the front derailer used on the left would have to be on the bottom. Could be done use a seat post tube flaten one end so you could bolt it the the axel and another small bolt to hold it from turning. ( or weld it ) It would hang down low but should work. Then you could use part of a rear derailer for a tensioner closer to the front. Just my thought...Curt
