I haven't tried to remove the spring yet, but all the other parts are there, and it is nice and clean. I'm using the model that fits to the campy shifter braze-on boss. I will dig deeper and see what I can find. Basically, there is no spring assist on the left lever one feels with retrofriction shifters. Thank you for the photos and guidance.
It is hard to describe the advantage of retrofriction shifters. With most friction shifters the effort it takes to pull or push the shifter is related to the tightness of the adjustment screw. On retrofriction shifters there is a spring inside the shifter that allows less "tension" on the adjustment screw lowering one's efforts on the downshift (rear derrailleur) making for smoother shifting with less trimming, but offers increased resistance on the upshift. For the front der. pulling back to shift to the big ring is easier than pushing it forward to the small ring. The shift levers counter balance the springs in the derrailleurs to some degree. Retrofriction shifters also reduce or eliminate the amount of autoshifting that occurs on some bikes. I have been using them for a long time (25+ years) and recommend them.
