I just finished up a new ride tonight.
59cm NYCBikes CityFixed frame (I know, I know, but I didn't when I ordered it).
IRO Rear hub w/ Velocity Aerohead
Nashbar Carbon road fork
Profile Airwing 42cm bullhorn
Salsa Cross Lever
Shimano RSX Front Hub, Brake, Crankset from my old road bike.
Mavic CXP something front rim. It looks very similar to the aerohead.
Deda Zero 80mm stem
KMC 3/32 chain.
It was getting late and dark when I finished tightening everything up and actually got to take a ride around the neighborhood so it was cut short. This is a fun ride. It's my first fixie, I need to spend a bit more time on it to get comfortable, but I came home with a nice wide grin after sprinting around the block about 5 times. I figure I'll put the toe clips on in a few days, and start looking for a better saddle, longer stem, and some MKS Sylvans w/ black cages.
