One option is a 17 X 21 Dingle cog (or White Industries DOS if you want a freewheel). If you use the 17 for a 70" gear, the 21 would give you a ~57" gear. If 65, then 53".
All this without the extravagant and appalling complexity of 2 chainrings. (Yes. That is a joke.) -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
