I have an Positron Open Road bike I bought at a garage sale for about a month ago. It’s been great for gravel roads and trail paths, but I’m looking for a road bike with more speeds to take back to school with me so I’m looking to sell this one. It’s in decent condition, it needs a few touch ups which I could easily do myself. Any information on this bike and how much it’s worth would be greatly appreciated.
Here is a link with a few pictures:

Wow… thats a name I haven’t heard in a looooong time.
The brand name isn’t Positron, it’s the model. The Bike was made by Murray for Sears- their Open Road brand which coupled with their Free Spirit models. Positron was Shimanos first attempt at indexed shifting.. instead of the shifter doing the indexing, the rear derailleur had ball bearing detents which didn’t always work too well. Big fat plastic shifters were on them to take the force needed to click each gear into place.
Anyway, insofar that the bike was experimental at best and that experiment failed there may be someone out there that might want it for posterity’s sake but I doubt it.
This probably isn’t the answer you want, but you paid about as much as it’s worth. Once that drivetrain starts to fail the entire system will have to be replaced, and since the remaining technology on the bike is pretty much obsolete, well, it will end up as junkyard fodder.
So, either keep it as a bad weather bike, give it to charity for a $20 tax writeoff, or put it in your own yard sale for, um, 7 bucks.
