I have a NOS Ridley Supercross frame I'm just getting round to building, but I'm struggling on the headset.
It's roughly 2008, it is 11/8", it is intergrated.
As it's old it shouldn't have anything fancy. What I can't work out is how you can tell if it's 45/45 or 45/36.
A kind soul pointed me to an add for a cane creek that said it would fit a Supercross so 45/36. But I seem to remember something saying Campagnolo type I've had so long now I can't remember.
You need the [url= http://www.canecreek.com/headset-fit-finder ]SHIS [/url] enter the measurements, and it will tell you.

It's unlikely to be able to tell you what chamfer angle he needs
Still baffled. There are no angles, straight 1 1/8 steered. 42mm internal sis top and bottom.
The Cane Creek finder will need you to give an angle.
42mm should be Campagnolo standard 45/45.
You could make some gauges cut out of card or from a drink can.
If you have bearings of the same diameter, you could try to test with engineers blue, or even a marker pen. Coat the bearing race chamfer with ink, fit into the seat and see if you get a complete fit or just a partial mark, either inside or outside of headtube shoulder.
