Building up a frame with 34 mm stack height. Since french-threaded Camp. Gran Sport headsets (34 mm) don't come up so much, I'm trying to find out what the stack height of the Triomphe headset is. It does look the same, but... The only other option I see (plan B) is a Stronglight P3, but there likely are other quality HS's with less than 35 mm stack height out there?
