Can you comment on how my DuoPar is set up on my Super Sport? Mine shifts very well, but I wouldn't call this 45 degrees from horizontal. Your suggestions are appreciated.
Sorry to be replying 11 months late.
In that orientation it is not functioning properly. The secondary parallelogram should be above the pivot with the jockey wheel very close to the cogs. The secondary parallelogram is not spring loaded like it is on the Suntour and Shimano copies. When oriented properly, chain tension supplies the force that lifts the jockey wheel to ride just under the selected cog.
