Can anyone out there help me? I discovered a broken spoke on my rear wheel on the freewheel side. I was able to get the tool to remove the Campagnolo freewheel but the parts are so badly seized that I cannot get the parts to unthread. I took the wheel to a bike shop and they have not been able to get the freewheel assembly apart. I had this bike assembled to my specifications in 1986. I ordered a 23 inch Eddy Merckx Columbus tubing frame and had it equipped with Campagnolo Super Record parts. So the gear cluster is from 1986, the freewheel assembly is from 1986. Of course the tubular tires on the Mavic GP 4 rims are new, as is the water bottle and the cycle computer. I changed the pedals to clipless a few years ago. I do not want to have to get a new rear wheel but if that is the only way I can ride this bike I will do that. I have a close ratio set of sprockets. I do not recall the number of teeth off hand but there is no big hill climbing gear. It may be that my 1986 campagnolo derailleur will not accommodate a larger set of sprockets. So I really want to be able get the rear sprocket set off so I can replace the spoke and get my retro bike back on the rode. Can anyone suggest a way to unseize these parts that are threaded together. Looking back on it I guess I should have taken that rear cluster apart every ten years or so, to make sure it would not seize up. Have I explained the problem well enough? I look forward to whatever help might be available. FYI I live in a small mining town in Northern Ontario, central Canada. The bike shop that I took the wheel to is a 1.5 hour drive west of my town, which is too small to have a bike shop.
