Finally got my bike finished today. Had trackstar install the headset and fork, then had them throw on the wheels that I built along with my other parts, because I was too impatient to take it all home and then bring it back down when the co-op is open. Here's the verdict:
Soma Rush Frame: Sweet
Brooks Saddle: They tell me it ages like wine...
Stronglight crank: Word
47x16: Just about right for where I live (uptown). Kinda spinny going downhill though. I'm going to get a 14t for the other side of the hub.
MKS pedals: Good. somehow easier to flip onto my foot than other toeclips I've used.
Nashbar bullhorns: Suck booty. Too wide and dont have a very interesting shape. I'm considering risers for the first time ever.
Promax hubs: They seem good in theory, but when they came loose after a few miles (normal on a first ride), the best adjustment that they could give me was tighter than I would like it to be. My next hubs will be higher-end.
Trackstar: Say what you will about them, but their labor is quality and their prices for it are reasonable. Their parts may be a bit taxed, but they didn't give me attitude for bringing them parts that I got elsewhere (or any more attitude than you always get at trackstar )
