    Shimano 600 headset stack height?

    Can anyone help me on two fronts? First I'd like to know what the stack height is for this headset. Shimano 600 off an 88/89 Merckx. No way to know if it is original but typical 7-Eleven mercks bikes came with Dura Ace or Campy. Mine had a mix of Campy c-record and DAce 7400 except for this headset.

    I'd also like to know the stack height of c-record era headsets such as c-record, Chorus, Athena, etc. I seem to remember these 600's being on the small side and wondering if I am stuck with this headset sort of getting new fork. My current fork's chrome is super nice so I don't really want to search for a longer one.

    If I can't fit an older campy headset due to height differences anyone know if a Chris King would work?

    EDIT: Found the CKing height their "grip nut" version has a stack height of 33-38mm. Still can't find 600 stack height info.

    Thanks!

    Thanks for the link...lots of good info. Did not know about the site. Surprised it did not come up in my searching. I figured you had to have the headset off the bike the measure stackheight...so much easier than I though. Mine seemed to clock in at 36mm but most listed on that site say 38mm, though they did not have my exact one listed. I asked an ebay seller that has on like me and he said 31.5mm

    Shimano publishes all of their technical documents, and even has old ones scanned in.

    Search by series

    600 ultegra

    HP-6400 first link should download the techdoc for you. It shows an upper stack of 21.5 and a lower stack of 11.5
