Thanks, that goes back to what I thought originally - i.e. that the outside of bb sizing applied only to 91 and 92. So this is a 1990 size 18, sized c-t, and with the top tube and wheelbase both half an inch shorter than subsequently, but with slightly longer stems to compensate.

I think lots of makes used Shimano dropouts at that time, didn't they?

Surely it's a 16" 1990 from the top tube length?

It rides like a much bigger bike though.

The catalogue figure will have been a horizontal measure, but I assumed that you took your measurement along the tube?
