There is no rifling on the steerer tube, but I thought rifling only applied to later SLX-SPX tubesets anyway. Also, anyone else have or seen a Cinelli frame with fender BOs on the stay bridges?
Hey, I forgot to add the most important part! When Brian Baylis put in a new down tube on my 1960 Cinelli S.C. he told me that it was a Reynolds 531 main tubed frame (the bike had been repainted way before I ever had it). And the steering column inside has rifling (indicating Columbus for the rest of the bike).
