Alchemy Bicycles (Austin, TX based builder) and their carbon fiber aero road bike:
Bishop Bikes (out of Baltimore, MD):
Blacksheep Bikes (out of Fort Collins, CO) - the first one, folks, is a 36er.
Boo Bicycles (also out of Fort Collins, CO) and their bamboo - carbon fiber bikes; love the bamboo headset spacer on there:
Caletti Cycles out of Santa Cruz, CA; the first (blue) one is an all purpose steel frame/fork combo built to take large tires for the occasional dirt road excursion:
Calfee Design out La Selva Beach, CA and their Dragonfly Pro with custom internal Ultegra Di2 package:
A rare EE crankset sighting (I was told they are good friends with the owner); they also had their brakes on this bike:
And the trick seatpost with a Di2 battery hidden inside (note the charging port right above the decal):
