Stronglight B10 B Hinault headset
 

Except for the fading lettering on the lock nut, it's in good condition.
The crown race and one of the fixed cups are plastic, it's very light.

PM on the way.

I'm glad you beat me to it, :). This along with the stronglight A9 is a really fine headset.

That's an A9 headset; the B10 had Delrin cups and race seats:

Yeah I was wondering about that actually. I run A9s on a few bikes and I have the B 10 on one (a 1984 Trek 610).

Damn it, I haven't even finished my first cup of coffee and I'm already wrong about something.

Actually, it looks like an A9/B10 "hybrid" A9's are all aluminium, except only for the bearing cages. It seems like the fork crown race and the top head lug race are B10 Delrin pieces..... So what it essentially is, a "lightened" A9.....
Forgot to mention, the top locknut is most likely from a B10, but those were identical to A9 locknuts, except for the "Hinault" model branding.

Ypu're right; I hadn't noticed that. :(


Both A9 and B10 headset were available with the Hinault branding. We went through thousands of them at Trek.

The headset was from a Trek 720.
