I posted three weeks back about a pair of really nice 1981 Centurions I picked up; one a Pro-Tour, the other a Semi-Pro. Fast forward to today when this arrives on my doorstep. A very nice, very original circa 1976-1977 Centurion Semi-Pro. I took a few photos before the daylight faded, it still needs a bit of assembly and adjustment, but you get the idea.

I've included photos of both Semi-Pro's; I'm afraid that I may be only able to hang onto one of them, unless another one of my bikes were to go away. Which one would you keep? Points in favor of the 1977: it's orange, it is the sister bike of a 1977 Pro-Tour that I own, and did I mention that it's orange? Points in favor of the cobalt blue 1981: it's gorgeous, unblemished, and has that fantastic set of drilled chainrings.

Which one would you choose?
