Interesting!
that's a different mechanism from the Landrider (another automatic shifter)

Looks like they use a low-normal rear derailer
then have spoke weights linked to a large movable 'dork disk' which slides laterally to oppose the derailer
I'd imagine it rubs a lot given that the disk spins with the wheel while the derailer doesn't...

Doesn't look like it has a shift calibration; maybe hackable by altering the spoke weights?


Again, Just get Normal Manual Shifters.
You're not happy with when the autoshifting is changing gears; means you've graduated to the point where it's time to take control and do the Shifting Yourself.
