      Standard 1970's geometry. 72 parallel. 27 inch wheels, 1 1/4 inch high pressure(!!) tyres.



      Actually, the frame was that old when I got it, it was probably from the 1960s.

      [mansplaining] I just realised what you might have meant. Not a penny farthing 67 inch gear. 48 tooth chainwheel, 19 tooth rear sprocket. Although it was a single gear, the sprocket was free, not fixed (actually, that comes out at 68 inch, I must have misremembered over the intervening 35+ years...)[/mansplaining]

        Does "mansplaining" mean explaining by a man or to a man?

        Just wondering, because as in this case it isn't always obvious.

          Well, since I acually quoted Pip...

            So, the 67 inches I took to be the size of the wheel (hence penny farthing) is the product of the number of teeth on your chain ring and your rear cog?

              The very aged among will recall that bicycle gearing was measured in terms of the equivalent penny farthing (properly called an "Ordinary") front wheel diameter, until most started having gears on them.

              Incidentally I have a certificate upstairs to the effect that I rode the Coddington Flyer, a genuine penny farthing, in the mid 50s. Since I would have been in junior school, I have no idea (or recollection) how I achieved that feat!

                No, it's the height of the saddle I think

                  And the wheel size (27 inches).

                  Thus (48/19)*27 = 68

                  Way too high for the ride in question. But I did it
