I've desperately been searching for an old single speed, but I have had no luck at all. I've found numerous 12 speeds and I'm thinking about converting one, I know a little bit about the subject but I still have no Idea what I would be getting myself into. I'm on a pretty tight budget and this will be the first bike of my own. Any advice would be greatly appreciated.

Check craigslist. I have seen a few SS and FG show up lately.

not to sound rude but try the search function for "chep fixed" or somthing like that.

i dont think "chep fixed" is a searchable term

so im illetarite ... crucify me

sorry dude, no offense...when it comes to spelling, i'm borderline OCD...

its cool when it comes to spelling im borderline able.

<laugh out loud>

So take the 12 speed, rip off the front and rear deralliuer, shorten your chain, and viola instant (albeit ugly) SS.

or do that ^^^ and just replace your rear wheel with a flip-flop....

will the dropouts pose a problem?

i don't think so... just get the correct wheel size for your frame and you should be fine...
