Quoted for truth. If you REALLY wanna go fixed, I'd suggest having a beater bike that you don't have to rely on to use as your toy. My "daily driver" is an 80s Ross Professional Gran Tour 10-speed. I didn't wanna screw it up so I instead posted an ad on craigslist asking for a junky road bike less than $100. I ended up buying an old beat up Schwinn. Started by taking it apart and learning what everything was. Then I bought a repair book and did repairs on it. From there I did what I could with what came on the bike. That's where I'm at now and I plan on buying some parts and making it into a trendy fixie.

That's what I suggest at least. But your miles may very. In summary, don't think about it and just find a way to ride.
