I'm now riding a Giant TCR carbon, 07, and a 07 Trek 5000 TCT. Both are full ultegra, except the trek is a 30spd and the Giant is an 18speed. The trek also has 105 sti shifters, other than that, beautiful bikes.
Bit more of a fan of the TCR but hey, they both are pretty close to the same. Huge fan of each.
And of course, I still have my old C.Itoh steel frame from forever ago.
