Correct about the headset, not a Stronglight clone, it has beefier rollers. Galli later sold a rebranded Stronglight, but this one isn't one of those.

We used to put this style on custom tandems in the early '80s. Dunno if they're actually more durable than most headsets, but we assumed so, just looking at them. Probably a lifetime headset. Careful, I have this vague memory that there's something hinky about the crown race seat/adaptor thingie, like thin/weak, easy to damage on removal? There was some headset back then that required a special tool to hammer on the crown race, maybe it was this Galli? Been 40 years since I worked on one, all I remember for sure is "be careful".

Oh yeah here's a pic of the innards fron the web, I see where the regular slide-hammer for installing would hit on the retainer that holds the rollers. So the tool they provided had a smaller diameter surface where it hit on the part that gets hammered onto the crown. (I think the roller assembly with retainer doesn't come off.)


Aha, here's the install tool, called out as "129":



And yes I think that lower flange, that you might want to hammer on to remove the crown race, is both thin and weak Al alloy. So removing it is likely to screw that part up. Luckily the headset will probably work fine without it, but then it would have a larger opening for dirt/water to get in. Use with fender only, from then on? Maybe someone here knows how to get one off without damage.
Very good to know Mark, as I was maybe going to sell the headset to recoup some (or possibly all!) of the cost. Maybe I better just leave it on?

Andy says he didn't braze it, and Mark was at Specialized by the , so who knows. Seatstay treatment doesn't look very distinct to my untrained eye.

How common were Gipiemme dropouts? I think this is a first for me.

Sadly no Strawberry BB shell cutout, not sure what era that was for them.

I'm not much for modern drivetrains, but I think some 7700 or Campy Titanium would look fantastic.

Only dreaming now, I have so many other projects to work on, and most of them aren't bikes.
