Having sold and serviced more then a few back in the 1990s I suggest you don't suffer more people with this. Does it work? Sure when all is well set up. But the auto principle is still lacking in shifting point control WRT the rider's pedaling pressure and the simple rotational based shift point is biased to the 50 RPM rider.
I might still have a take off in my stash. We changed out to the common cable controlled systems on more then a few of these bikes (GT had their Air Stream versions too). Andy
