Howard - I agree, that Sedisport chain was a major breakthru - I have 2 rear wheels built for me by Bill Bryant in that low dish configuration, and after 20+ years of riding they are still true as can be! The narrow chain - somewhat stiffer laterally than the Regina - plus the ultra 6 freewheel was a significant breakthru in precise shifting, and a step that I don't think is mentioned in "the dancing chain".

By the way, I recently visited Jeff Groman's new shop and saw 2 copies of "the dancing chain" for sale, still in the shrink wrap, so if anybody's jonesing for a copy, Jeff has them!

Maybe it's my ADD kicking in - but Dan, your best bet on the 5 speed campy axle is ebay seller "wwcycles". His online manner ain't great but he has the axles for I think $12 and you get 2 new cones and all the spacers & locknuts too!
