Everyone's probably tired hearing me wanting a crankset for my '76 Schwinn Superior 10 speed. Why is the Nervar crankset so hard to find? I thought the Superior was a commonly found bicycles in its day. I have found a few Nervar cranksets but nothing close to what I am looking for. I actually found a picture of the original crankset for my Superior on someone's blog. After contacting the individual, the Nervar crankset was not for sale. There's got to be more than one bicycle that used that particular crankset.
