Early 1900s bicycle tyres can be a pain to match with modern equivalents. After dealing with so many over the years, I thought I’d seen every tyre size …then a few years ago I bought an early 1900s French bicycle and discovered it had a tyre with the size 28 x 1 1/5″ !
I shared a photo of it on facebook and a chap in Norway sent me a message to say he had one the same size for sale. So I bought it.
Just to illustrate how ridiculous bicycle tyre sizes are …his tyre had exactly the same size markings on it, BUT IT’S BIGGER!

SAME SIZE …BUT BIGGER
