Okay, so Sheldon says that there should be a little play at the rim when a SA hub is adjusted correctly. Another friend who has spent a lot of time with three speeds swears that you can remove all play, as with a normal hub. I currently have it adjusted so that there is play, and in fact, could not adjust it to remove play when I set the wheel up. As a consequence, I feel like I get a fair amount of vibration from the wheel when coasting - I can feel it through the frame. Any thoughts from you three-speeders?
As I recall (and I may be mis-remembering), it came down to the cone and anti-rotation washer. The washer only allows four positions for the cone, 90, 180, 270, etc. I'm pretty sure I had the left side maxed out in terms of tightening, so no option there. I might be missing something.
