Schwinn is offering probably the most base fixed gear bicycle available for 2009.
Pros: Sealed hubs (The Langster doesn't offer this), the 1 1/8 threaded headset can be converted to threadless with a little bit of money (which I would recommend after seeing Chase's bent fork*)
Cons: Semi sealed BB, crankset is cheap
Projections say the bike should be available now, but at this price good luck getting your hands on one. Here are all of the specs.
See what other people are saying over at urbanvelo.org.
*Caveats: Chase was jumping down a 3-set and his fork is about 20yrs old.
