There is a 21.15mm size for steerer ID, where the steerer OD was still 25.4mm (1") - i.e the steerer is made from thicker tubing that the regular 25.4mm OD/ 22.2mm ID. Was common on BMX and on some early MTBs and one-piece crank bikes. Not as small as 20.6mm though.

Egghead, thanks so much for that wisdom! I’ll get him to check his internal dia with this in mind. I was wondering if the old headclip type bikes might have had tiny quills.

Next stop the VCC brigade, to see if there’s an even teenier quill size back in the mists of time.
