I got myself a road bike and i'd like to make it into a fixed gear for as cheap as possible.
I know with the front sprocket i can pretty much just use whatever size i want and adjust the chainring bolts. My main problem is what to do with the rear cassette. Can i just keep whatever size cog i want and take the rest off making some sort of spacer and weld it in place ?
