I dare to go against the knowledge and wisdom of juvela at my peril, but I would guess a couple years later The combination of the under-BB cabling makes me think it is no earlier than the late-70s, and the five-speed rear end makes me think it's no later than the late-70s. I am prepared to be humbled by my betters if my thoughts and assumptions are off base (it wouldn't be the first time, it wouldn't be the last), so have at me.

I saw Kareem riding out San Vincente Blvd in West LA/Brentwood c.1981. In my memory, his bike was significantly bigger than that - his wheels looked stupid-small on his very big frame, and these wheels look within spitting distance of normal compared to the frame. (Of course, I ride a 64cm frame, so that clouds my perspective.) I'd guess that to be about a 68cm frame, as it looks like I could ride it, although all stops would be an adventure for my naughty bits. No way I could have ridden the bike I saw Kareem on.

Robvolz, are there any distinguishing marks on it at all? It's a beautiful bike and it would be great to give proper credit to the builder. It also looks a smart "bang for the buck" build.
