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?
