Default Campagnolo 1" Triomphe headset crown race sizes?

I have a Campagnolo Triomphe headset that i took off a bike that I then rebuilt for a friend. The crown race on the Triomphe crown race has a smaller internal diameter than does the one on the 1" headset I replaced it with on the bike.

1. Does anyone know what internal diameter is the Triomphe crown race I do believe it's English threading as that was the threading of the replacement headset.

2. Anyone know where I can buy that smaler inner diameter crown race? Or a complete Triomphe headset at a reasonable price with reasonable shipping?

Cheers

Any help at
http://www.velobase.com/ViewComponen...c-f21446a9b792
which lists two possible threadings - English/ISO/Italian (25.4mm x
24TPI) or French (25mm x 1mm)

The two sizes are 26.4mm and 27.1mm.
Generally premium quality bicycles use the smaller crown
race seat. The matching head cups are 30.0mm and 30.2mm so
one generally cuts a midprice frame and fork to the smaller
crown seat and larger head tube.

In practice, ignoring the 0.2mm head cup difference doesn't
seem to be an actual problem.

I think you want frame machining service, not a new headset
but if you want one they exist:

Thanks Andrew.

I'm leaving shortly to put the Triomphe headset back on the buyer's bike. That means I'm in the market for a Triomphe or Victory headset for my Miele Tange Infinity frameset.

Cheers
