Fixie commuting wheels.
 

I'm building a fixed gear commuter and I am looking for the best possible wheelset under$300. Any help?

Not much help on the bike knowledge, but been commuting for a few weeks on fixed gear myself and love it. I really recomend a front brake. My poor geared commuter has seen very little use since I put together the fixed gear, only if I have to carry much of a load.

I have Deep Vs on mine. I think I paid around $200-ish shipped from velomine.com I don't know if they're 'the best possible" but they work fine for me. Never had any issues and they look nice IMO.

IRO house brand; around $150 if you have them built up. Less than $100 if you go the route I did and build 'em yourself.

Cold Fusion rims = $30/pair
IRO high flange hubs = $40/pair
DT Champion 2.0 silver spokes = $45/box 100

For commuting I would suggest:
Rims: anything semi-aero and > 22mm deep
Hubs: nothing wrong with your basic Formula hubs
Spokes: anything 14 gauge unbutted in the rear

talked to a guy a few days ago who had some neato looking ones on his SS. he told me they are called aerospokes, haven't had the chance to google them yet but they looked niffty.

aerospokes are over 300 each new...
