I bought a Raleigh Marathon 12 speed bicycle from our town dump for only $30. It is in awesome shape and it looks like the previous owner never road it. I replaced the shift cables, which were a little rusty (although I probably could have just cleaned up the original cables with some oil and they'd be OK).
Yesterday, while I was tuning the bike, I noticed that the rear wheel makes noise when rotating. It sounds like the freewheel mechanism has a lot of friction. When I had the bike on the work stand, if I cranked the pedals, the rear wheel would turn, and then when I released the pedals, the wheel would continue to rotate, but I could hear some friction sounds and the rear wheel would pretty quickly come to a stop. I also noticed that when I turned the pedals backwards, the rear wheel would rotate backwards with the chain instead of staying put (if I started pedaling when the wheel was at rest)!
I road the bike for a few minutes, then put the bike back on the stand to do some more tuning. I tested the freewheel again and this time, when I pedaled backwards, the wheel didn't turn backwards, but there was still significant friction and noise and whenever I stopped pedaling, the rear wheel would come to a halt pretty quickly.
Does this sound like a problem with my freewheel or is it something to do with the rear hub? Do you think it would help to remove the freewheel and then clean and lube it? The front and rear hub on the bike look like they are in good shape. I'm wondering if maybe I need to lube the freewheel or something, or if I have to replace the entire hub/freewheel combo.
Any advice on what to check?
