Another thing to consider, if you don't want to modify a SRAM Automatix's shift point (seriously, SRAM, is it too much to ask for an easy spring tension adjuster? Doesn't even have to be as easy as the old Shimano AB-100, just something external), is the Sachs Duomatic. Long-term reviews of the Sturmey-Archer S2C are almost universally bad, but you can find old Duomatics without too much trouble. (I got one from Jens of scheunenfun.de.) Bonus, the old Duomatics won't need the rear triangle to be widened (I'm at least assuming that it's a 110 mm rear triangle on the Speed...)

Now I just want a front drum brake (because I hate rim brakes), but Greenspeed apparently doesn't do the 74 mm Sturmeys any more, so I'll take a dynohub instead and live with the rim brakes.
