IF it is an integrated headset there are only two in common use. the 36/45 degree one and the Campy 45/45.

yours will be the 36/45 version just get new bearings bearing number will be on it. if a cartridge eg 873-2RS

Many thanks for the suggstions, I just have the bare frame, with no parts to reference or measure. I suspect someone (previous owner has tried to fit the wrong one ) !

Have now cleaned up the damage and the best measurements I can get are as follows

Top Diameter 41.00 mm x 3.2 mm deep into a 45 Deg Angle Face

Bottom Diameter is also 41.00 mm x 7.23 Deep into a 45 Deg Angle Face

The Qutside Diameter of the Head Tube is 46.00 mm

Best I can do from Bikepedia was it's a FSA Intergrated Headst, but it gives no detail ?

Cheers JW
