ALCJPHIL:
You are preaching to the choir. First, on my 1989 hand-made Ritchey Mountain Bike there is a non-native Sachs Aris Freewheel Sprocket(s) that is not performing well with the Mavic Hubs. I can't use my Rapid Fire button anymore because of a piece-meal set up (on my Ritchey). But let me cut to the chase, because I have an Ochsner Road Bike (Columbus Tubing) with Campagnolo drop-outs and Campagnolo Record Hubs and derailleur says Nuovo Record that I need help with. I want a Campagnolo Freewheel that is compatible with my setup because my pulley wheels are cracking because of non-native Suntour Freewheel that is on the bike (currently). I found a beautiful NOS Vintage Campagnolo 6 speeds alloy freewheel 13/21 and trying to see if it will work with Campagnolo Record Hubs and Nuovo Record Rear derailleur (but the price is ridiculously high and I want as many options as I can find because I don't want to pay $595 for that Campagnolo 6 speeds alloy freewheel 13/21 ! Please help!
