Project P2 calculations

[Harryburgundy]

I have these for sale with someone interested.....
http://www.retrobike.co.uk/forum/viewtopic.php?t=147260
and I'm trying to work-out the size frame they are intended for

The steerer is 180mm with 32mm threaded. Using my calculations based on a Chris King headset with total stack of 38.5mm, that would leave 5.5" of steerer in the headtube....quite a large frame then.

The weight is 839g which I'm guessing is TB territory?

Am I in the right direction?

I agree that anything under 1kg is usually TB unless it has almost no steerer at all!

410mm TBs with a full length (240mm) steerer wigh in at just under 900gm, so yours seem to be TB.
I think, though could be wrong, that a 19" frame had a 15cm headtube.
Dropouts are TB style, but I seem to remember " T R I P L E B U T T E D" written in the orange of the logo...

Size 20" have the 15cm headtube, 19" are 13.5cm i think
