There are three Soma bikes in my house:
Soma Smoothie Race, built up w/ Ultegra 6700 group, IRD Cadence / White Industries wheels, Thomson goodies. My road bike.
Soma ES, built up w/ Dura-Ace 7700, Salsa / Ultegra wheels, Thomson goodies. My girlfriend's road bike.
Soma Buena Vista, 42cm (uses 26" wheels), single speed, Velo-Orange Milan bars, etc. My girlfriend's daily commuter.
I also run 456 track bars on my track racing bike, Clarence bars on my singlespeed 29er, and various other Soma bits on other bikes in my collection.
Considering either a Soma Rush or an All-City Big Block for a fixed gear road bike and backup track racing bike, altho I'm leaning towards the Big Block.
Soma stuff is nice and well-designed.
