The SA 2010 catalog is awesome, I wish one of my LBS carried the full line. Look at the fixed 3 speed hub for instance...although I wonder how hard that would be on the knees during shifts... Anyway, I just purchased the SA 8 speed drum brake hub for a future build, and it is approx 132mm. I tried it on a 120mm track frame and the amount of forging needed is just a bit too scary for me.
