All I can say about the $900 bid for those cranks is wow. On my Cinelli, I have a set of cranks that are identical including the condition. I have no intention of parting that bike out though, as it has way to much meaning to me in it's current condition. About the only thing I might ever do is get some other crank set as a user because I do plan to ride this bike.

I have a question though related to cranks. How do I determine that the taper on a spindle is appropriate or not for a crank? I checked Sheldon's web site but couldn't find a discussion of spindle tapers that I thought I had read there before. My hazy memory is that there are two more common tapers but that there are others as well. One taper is one commonly used on on-topic campy cranks, and the other would be the standard found on most japanese parts. However, would some Japanese components have the same taper as campy? The reason I ask this is that a bike I bought (specifically to part out. Nothing was 'original' on this bike anyway) had a campy bottom bracket set, but Sugino(?) Super Mighty.

I was playing around with different spindles I have and different cranks and it appears that some Shimano spindles might have the same taper angle but start out with a wider end. I found I could fit some cranks onto the campy spindle much farther than the campy crank would go on the campy spindle, and the campy crank would not fit nearly as far on the shimano spindle as the newer SR or Sugino crank would. In all cases though it appeared as though there was contact both fore and aft along the taper. Can someone enlighten? Thanks.
