I suspect that the parallelogram fork of the Simplex isn't such a good idea as they suggest; it would work fine if the chainline remained parallel t o the chainring and the rear sprockets, but it doesn't (except, if line d up correctly on a three-speed block, on the middle rear sprocket) - it bends, and the Super Champion type fork follows the chainline. It seems to me that the chain would be more likely to rub on the fork with the Simpl ex parallelogram, since it won't follow the actual chainline.

If you refer to http://smg.photobucket.com/albums/v396/hadendowa/Simplex%20 Super/ you'll see that Simplex advertise the "advantage" of the parallelogr am, using an illustration which misrepresents the actual chainline.

I would be interested to know, Mark, whether the fork on your derailleu r actually does rub on the chain in practice, since I've never seeen one in operation.
