I'm finding it hard to track down a 27.2mm Dura Ace EX seat post to complete my 1979 Bruce Gordon (http://www.wooljersey.com/gallery/simonpj/Bruce+Gordon+1979/).
The one that I used in the photos is 26.8mm - and I would be happy to swap it for a 27.2mm It's in very nice condition.
Or I would be delighted if you have one to sell.
Many thanks,
