I found:
Profile Designs Aris Bike.
https://www.amazon.com/Profile-Desig...-14&th=1&psc=1
That seems like it should work since the stem is made by Profile Designs who also makes the “Profile Designs Stoker 26 Bar.”
I can probably select a height based on the height of the bars for my stoker on our other tandems. I suspect the shortest length (60mm) is likely the best choice. But, how do I choose between 83 degrees and 115 degrees? Here is a picture of where the stem is going. Thanks for any suggestions.
