Generally that's referred to around here as "ghost shifting." It happened to me when I tried the original SunTour Sprints on an 8spd Moulton. I then used the same shifters on a Kogswell P/R set up with 7 spd Hyperglide, and shifting is great. I believe the problem is 8spd is just too close for me to accurately shift a system that doesn't give much auditory feedback for misalignment like Hyperglide. One thing that's been suggested a lot over the years is to swap the upper and lower pulleys, so that the upper pulley is the one with no float at all. You might also try doing your downshifts with more load on the drivetrain. When I shift my Kogswell that way, the gears change with a PLUNK, quite positively. That's entirely counter to how you would shift an old-time friction system. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
