Not sure how a stem change could induce a no-hands shimmy. I suspect something else is the cause.

FWIW, I just changed a 95mm SR Royal stem to an 80mm Technomic with no shimmy problems.

FWIW, the threaded post on the 2033 lever clamp is standard 6mm x 1mm thread, so pretty much any nut of that thread will work. The 2038 washers might be more of a problem.

The pedals look more like Cyclone (or the MKS analog to Cyclone pedals) than Superbe. But still, for $20 it's hard to go wrong.
