This is what my Angus looked like with a black frame and silver parts. I thought it looked pretty nice.

If I were getting one of these, I think that I would actually get a Mark V singlespeed. It costs $450, but comes with two brakes, which might come in handy. Then I would just buy a cog and lockring separately.

If this is your first fixed gear, I would want to hover around 70 gear inches. IRO chainrings are 46-tooth, so I think I would go with a 46-17 setup. I got mine in a 46-19 setup, which made a great setup for taking it easy and working on my spin. Look for more skid patches, as you will probably want to skid like crazy.

My wife's Mark V came with 28s on it. My Angus [2 years ago or so] came with 23s.
