Just acquired a '74 Jack Taylor Super Tourist Tandem. No size markings on the seatposts. I have measured them at 26.0 Is this correct?

Thanks - Lorin

Did you use a good quality caliper? If so, then it is what it is...

My 1975 orange Jack Taylor Super Tourist has a 27.0 diameter seat post.

I can't speak for Jack Taylor tandems (which back in the 70's, prior to Santana, was pretty much the standard tandem everyone wanted), but when English-made frames flooded the North American bicycle market around 1972-74, a lot of them were complete crap. One way you could tell just how crappy an English-made frame was: measure the seat tube diameter. Reynoilds 531 db should be 27.2mm. If it's 26.8, the genius of a framebuilder put the seat mast in upside down.

English-made motorcycles, with their vertically-split crankcases that leaked oil like crazy, were also losing market share to Japanese motorcycles at this time, too. Eventually, Triumphs, Nortons, and BSA's disappeared...

Thanks for the update. The 27.0 mm seat post in my Jack Taylor Touring single bicycle with Reynolds 531 db fits fine. Is there a market for selling Jack Taylor frames? Mine is about a 21" with aluminum fenders holding-up front and read panier racks.
