I have a s3x, black (currently mounted on gold deep v velocity, with black dt swiss spokes - but up for potentially splitting) 36H with a matching 120mm flange black SA hub laced to the same setup - except this rim has machined walls.
It works pretty well as a geared system, I used it for a month while I was up in scotland (the reason I built it up in the first place!) but now I've had to move back to Cambridge/London for work so it's not really as much use here - alas!
Took a few rides to get properly set up and adjusted, but works smoothhhhhh.
