> For perfect shifting or to get larger cogs I use a modified 7 speed Shimano Cassette cog (pre-Hyperglide when possible) for the inner cog, then a 1mm freewheel/fixed cup spacer then a dished small cog. http://bikesmithdesign.com/SA/2Cogs2.jpg http://bikesmithdesign.com/SA/2Cogs.jpg http://bikesmithdesign.com/SA/CogMod.jpg shows how the cassette cog splines are altered.

When Jane was recovering from a knee injury I put a 22-34 pair on her SA 5 speed hub. Her Huret Duopar shifted them as smooth as butter. http://bikesmithdesign.com/SA/22-34.jpg < --------------------------------------------------------------------------------------------------------------------------- Mark and list: Pretty interesting info in this thread. I thought I remembered reading about a maximum rear cog size on a S-A hub due to overloading the hub and stripping something. Maybe it was a newer/different brand of hub. That shot of the 22-34 is still impressive though.
