Frejus seat post diameter?

[oldbobcat]

I'm in the middle of building up an old (late 50s or early 60s) Frejus track bike, and I cannot get an accurate reading of the seat tube ID using calipers. As far as I can tell, it's smaller than 27.0 and larger than 25.4. It uses a separate binder that fits over a flange at the top of the seat lug.

Is there anybody out there familiar with the marque who can tell me what seat post size(s) will work?

Hello

Seatpost might be 27.0

I bought a 2nd hand Frejus track bike last year, fit it with a 27.0
Great bike so far. I bought the seatpost through the Internet, the original seatpost-rails, 50's Campagnolo, do not fit modern day Saddles

Regards

Thanks for the tip. I think mine is smaller, though. We tried to stuff the post from a Bridgestone MB-4, which I'm told is 27.0, and couldn't get past the slit in the seat lug.

I just bought a 26.4 for 5 bucks, so we'll see.
