I bought a Super Galaxy about ten years ago and a 1976 Galaxy about five years ago, one of those pretty green ones with chromed forks. I got rid of them when I bought the Ranger.
You're right, it's an 80's mountain bike / all terrain bike.
With a silly sticker that brags .....

It's hard to keep the collection down when there are so many nice bikes at the dump going so so cheap!
Can you really keep it down to just ten?
Sell your bikes and buy some more tents maybe?

Edit: Just googled Ferrari road bike.....OMG, you have one of them

Yes. Been looking for someone that wants it. Too big for me. Needs a tall person. In this area older bicycles can be difficult to sell. I often find it costs more in parts then I could sell them for so many I scrap and take parts off them.
One of my 531 bikes has a Sachs Elan hub gear. I am planning on building the hub onto another bike and selling it, as it is currently on a mid 1980's 531 Sports Touring frame. I think I need to start a new thread for bicycles!
