Hope I'm in the right forum.
I have a Shimano two-notch 600 freewheel (13 - 26) on a Shimano "Sealed Mechanism" large-flange hub laced to a 26- inch Ukai rim. Early 80's stuff I think. The freewheel is in pretty good shape and works, but it will wear out eventually. Do any of you freewheel experts out there know whether I can replace this freewheel with a spline type (such as an IRD) when the time comes? I don't think it's going to be easy to find a Shimano 600 two-notch freewheel.
Thanks in advance for any input.
