Super Schwinn Suburban Score

[oldschoolcolo]

Just picked this up. Looks like Copper paint. All OG except for the tires. Everything is Schwinn. Has the crazy drive train where the front chain ring rotates. Is there any reason for that?

Thinking this is from the mid1970s. Enjoy!

Interesting, but why? Was the performance supposed to be better?

I think its so you can shift when you're not pedaling

I think that color is called chestnut. It's not the coppertone. Gary

that's the Positron drivetrain. I had a Caliente that had that set up, pretty neat to watch it shift while coasting.

That's a beautiful bike. I have a few Schwinns , but am not familiar with that drive system. It's interesting. I'm going to learn more about it.Anyone know of a good source of info? I believe I'll go see if Sheldon Brown had anything to say about it. :?:
