Sturmey Archer axle length/sizing question
With the various choices of axle length for any sturmey archer hub is it just the axle, shell, nuts and toggle chain that differ, with all other internals being the same?
I think in some instances the shell is the same and the axle nuts and axle account for the OLD specification, but in other instances the shell is different.
I'm guessing there's always potential on the left side/non-drive side for changing proportions so it wouldn't make sense to have different driver/pinion etc specs. . . ?
