Has anyone tried a s3x hub in an old Sports frame? Looks like there's a 5mm difference in OLD, the hub being wider than the dropouts.
This is interesting to me both as a slippery weather bike and also, perhaps, with a freewheel screwed on and a derailer.. kind of a modern-day cyclo kit...
Was 3 spd fixed ever an option on a bike like the Sports or was it really found only on road/racing frames?
