You can use any freewheel you want, and the rear derailleur , as long as it's within it's total capacity(which can usually be stretched) will work just fine. Minor hi/lo screw adjustments but that's easy.
As far 8 and even 9 speed freewheels, yes, they are still on the market. Sunrace and DNP makes them :) -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
