I think, from looking at the decals available for sale on their website, it's a 2002 Litespeed Siena. It was very filthy when I got it - years of caked on gunk. It cleaned up nice though, and rides nice too!
Looks like a nice bike. If you don't mind my asking, how much did you pay? Is that steel or titanium?
Great either way, just curious!
It's Ti, with 10sp Campy on it. $500! Course then I had to go and change out the bars, stem, bar tape, saddle, and tires... And it needed new brake pads and a couple of cables replaced.
