Freewheel spacer for fixed gear?
I just converted an old Raleigh to a single speed and I want to economize as much as possible by saving the original wheels. I have the chain rigged up to the small sprocket in front and the second cog in the back and the chain is lined up pretty good. My question is does anyone sell a spacer thingy that I can use instead of the original freewheel? Meaning, I want to buy a single cog and lock ring and use it with the original 10-speed hub. Is there a spacer I can buy to help keep the chain lined up or am I looking at a dicey situation? I want this bike to be a reliable fixie not a rigged safety nightmare.
This is not a cassette set-up. It is a true freewheel old-school 10 speed.
