Never tried adjusting a Shamplex before, hence the reason why I was stumped with the Gran Sport.
Wouldn't it have made a bit more sense if they had made a small adjuster spring and screw on the inner end of the rod? Would have made it easier for sprockets that sit a few MM farther out then the norm (running a 51t on the inside).
Take care,
