I bought a bike when I was 16 from my bike club - it was donated by a racing team - no idea which one.
I have got round to rebuilding it now - it has cinelli-like holed lugs, brazed campy 1010 dropouts, phil wood english BB, 27.2 camp post, 1" cinelli headset, chromed rear and forks. The BB has SP 91 pressed into it and also similar on the steerer tube. Would be nice to know who or what SP is - 91 is not 1991 as I bought it early in 80s. Any ideas?
I have attached a link to pictures for anyone with a keen eye - thanks...
