Trust me...If the CAAD 7 framesets were anywhere near on the horizon, I would have one. My CAAD 3 weighed in at 22 lbs though and handled rough (pre-wishbone stays). I have some really big races coming up and couldn't wait for C-Dale any longer. Besides, the old frame will make a nice cyclocross bike.
I just like having to assure the airline personnel that "yes, there Is a bike in the box" (he he)...all 16.5 lbs of it!
I haven't heard of Airborne at all. If they are too inexpensive I'd be wary. I've worked with many metals and know that the $ for a ti bike is driven by the craft it takes to work the metal not by the metal itself.
SEVEN makes a sweet custom only bike...beyond my budget.
