So what happened to "Optimo" aluminum tubing? Cannondale spent years making a pretty big deal about the stuff...it supposedly was proprietary, and according to their own marketing literature, which is still in the FAQ section on their website, Optimo was superior to 6061 and 6069 Al.

Yet the new CAAD10 is made with 6069. Says so in the specs.

Was Optimo just marketing BS? Or was it another signature piece of Cannondale lost in the move to Asia, fading away with the "Handmade in USA" label on the seatstays?

I love my CAAD9. I wonder about this new breed.

By the way, isn't the CAAD10 in black anodized? As cool as that is cosmetically, Jobst Brandt and a lot of technical literature have things to say about anodization of thin-walled aluminum structures and the propagation of stress fractures.
