I saw far more ti bikes at CO than in the past three years.  That may be in part because the route was flatter so less emphasis on weight and more attraction for less than stellar climbers.  But the difference was big enough that I have to believe there is some change in perception.

The bikes I saw include Merlins, a few Serottas, a few Sevens, a Dean, a Sage (a bike imported into Portland, designed with input from Dave Levy of TiCycles and inspected by him) and several others,  (I never got organized and wrote the names down.)  There was a ti tandem with massive tubing from Pennsylvania ridden by a couple who loved it.

I think the word is getting out that ti is an awfullly nice material if you ride chip seal.  I think people are starting to notice that when we hit nice pavement that the steel and ti riders aren't singing out "Ah!" and also aren't slowing when the rough stuff appears.
