Tried to fit a NOS Tioga beartrap 2 headset into a NOS Haro frame today and it was not having it. So i checked the diameters and to my surprise the internal of the head tube is 32.1mm and the external of the headset cups is 32.6mm ??? I would say there's not much chance of it going in. Anyway i have a mate with a tube reeming kit, so nipped round to borrow it only to find that it only goes out to 30.5mm which he assures me is plenty for doing standard/early roadbike mtb frames with 1" threaded steerers. Now im completely stumped.
Anyone else come across this issue and any ideas what to do or where i might get it resolved?

What sort of haro frame those headsets usually fit 87 88 and 89 I'd say

is the frame and the headset painted , powder coat can be quite thick , could account for the difference , 1" road bike headset is smaller than whats considered 1" bmx

Headset is chromed, so is the frame. inside headtube is bare metal though.
