Most things are fashion or fad driven cycling being no different. Prior to 1939 the normal wheel size in the UK was 26". Sometime after the war Dunlop amongst others who were rim makers and tyre manufactures decided to introduce the 27" rim to corner the market. This is what I have been told by the old-timers. By the early 1950's the normal British standard rim size being ridden was the 27". The 26" being virtually extinct and only ridden by a few of the old diehards. These dates are approximate. Like I said there was a transition period. I am sure some of the other Brit members will elaborate on this subject. Best wishes and be lucky. Michael Butler Huntingdon UK.
