Bought this bike today mostly because of the early black dura ace group. I think is all 77-78. Frame based on color. Components are not original as this bines didn’t come with dura ace. Also wheels are 27 x1 1/4 which are also not original, in fact they barely fit, originals where 700. Seat post is stuck but I think I ll be able to get it out. Frame should be Reynolds 531 but decal is missing.
