Ah, just twigged what the 8mm is about, I'm from the era of PMP cranks and no, I didn't buy them for obvious reasons lol
I learnt to ride in the 60's where we tied blocks of wood to our feet or pedals to be able to ride bikes that were too big for us, I shudder at the loss of efficiency :)
Yes, but since your understanding of geometry is so flawed, can I interest you in some PMP cranks?
