Hello!
I have lately bought a couple of 20” Avon SM front tyres in Spain. I got them from “AAW” whose website is the following: www. aaw-bcn.com I hope you find what you need! And please answer back for me to know how is their spares stock functioning.
However, I could not find 20” tube-type so I took a 19” one in my 20” tyre and it is runing without any problem. Of course there are different solutions for each model so I let you know mine is a 1929 Flying Squirrel.
Kind Regards
