    cartridge headset match (or go with ball bearings)

    I am repacking a bunch of headsets this weekend and one has me a bit stumped.

    the headset is Shimano 600 but it has bearing cartridges not simple bearings. (or at least the cartridges shown in the photo are what came out of the headset when I took it apart.)

    My LBS tells me a) they need to know the headset type in order to match the worn cartridges (I couldn't remember when I was there this afternoon and so I would like to avoid the need to return) and B) they might not even be able to get them anyway.


    But it doesn't seem right does it make sense that this setup (Shimano 600) would require or take cartrdge bearings (I would have thought cartridges post-dated 600) and if not, can I use straight ballbearings instead? and if so, what size?


    thanks

    To answer some other questions, cartridge bearings have been around for a long time. I don't know how early their use in headsets started but everything I've read on your particular headset describes it as using cartridge bearings. Headsets designed for cartridge bearings definitely can NOT be used without cartridges and just balls. The cups are not designed with the geometry or material spec for loose ball bearings.

    +1, forget guessing the vintage.

    Headset either have ball races to accept loose (or in retainer) balls, or seats to accept cartridge bearings It's strictly one or the other, and can't be switched.

    The cartridge bearing Ultegra/600 heasdet was HP-6500. They date from at least 1995 as I installed one on my new Litespeed that year. They were, BTW, a great headset. Very durable, smooth and a real bargain.

    The earlier loose (retainer held) ball 600 headset was, IIRC, HP-6200.

    The bearings in these two models were definitely not interchangable.
