Had a few moments in the garage today....
first thing was to check the Pure TT 70's Jackson headset, Alloy EDCO Headset, cost me a fortune but the weight saving was worth it LOL Used to run the Jackson with Campag Pista for which it was designed but seduced by the alloy EDCO
Then remembered 36 years ago with horror that there was no room for a spacer so just put the locknut against the top race. at least the forks wouldn't fall off if the locknut did.
Had a Look at the San-Remo, yep, 36 year old Tange Falcon Locknut but no Falcon type groove in the cups.....took off the locknut here
Then the top race.......and blimey it's a Campag Pista !.....then there are a shed load of small balls all over the floor, forgot they were smaller than usual and not captive.
Now wonder where the rest of Tange headset is, where the Campag Pista locknut is and also where is the Campag Strada headset I bought for the San-Remo?
I'd buy the Tange Falcon from e-bay if I were you
