Product Description
1st gen Dura Ace bar end shifters from the 1970's. These are not retro-friction, but employ a spring mechanism to create a very light feel in both directions. Retrogrouch explains it as "The spring in the rear derailleur is typically "high normal" - in other words, its natural position is to be in the high gear (smallest cog). The spring in the lever is "low normal" - in that it wants to move the derailleur to the lowest gear (largest cog - and by the way, this is all completely reversed for the front derailleur). To set them up, you have to move the lever against the spring to the opposite end of its travel and hold it in place while you pull all the slack out of the cable at the derailleur and then tighten the pinch bolt. It helps to have one of those cable pulling tools, aka a "4th hand tool." When you have them all set up properly, the two springs basically fight it out, tug-of-war style, and the derailleur stays in place where you put it. The movement takes a fairly light touch as there is very little friction."
