I'm still mulling over bottom brackets. For my Atala, I need a pre-CPSC Italian bottom bracket. One of my Chicago area bike buddies likely has the part I need, but that doesn't keep me from scouring eBay. I came across this eBay auction a few minutes ago. It seemed odd to me. I think the spindle and cups are mismatched. The cups look to be thin (Record?) cups, while the spindle (70-SS-120) should be for Nuovo Record cups. Perhaps there is a meaning to the "Z" suffix after all? Rather than just link to the image in the ad, I've uploaded it, should it be useful for readers who come along in the distant future.
