here. I believe Ashtabula is Greek for
Boat Anchor. Good luck with the project and post some pics
The 73 SS below has the one piece crank -it weighs a ton
I had a 1973 Super Sport in Lime Green when I was a kid. It was a VERY heavy bike, and yes it had the one piece crank that was not only a boat anchor, but the anchor from the Titanic. I road that bike a lot as kids will do, as it was my only form of transportation, however, I never really liked it as it never shifted well, nor easily. Plus the weight. I ended up giving it to my cousin when I turned 16 and could drive.
The only decent thing on it was the Brooks, leather saddle.
