So how much is too much? How many times is too many times? Who knows, because the answer is really only known when the frame starts to crack, or doesn't. Andy.
In most cases, that plus or minus is a fairly significant number when dealing with Sturmey Archer hubs. I've mounted SA 5 speeds between dropouts ranging from 113mm to 135mm by adding, subtracting, re arranging spacers and nuts, and at the upper end, mounting the anti rotation washers inside facing out. Lots of flexibility there.
