Hey, here's a photo of my pretty new 2008 Giant TCR C3 with my 2007 TCR C2's Ultegra/105/Race Face components installed (and Easton EA50 wheels):
And here's a closeup photo of my old, poor, broken 2007 C2 frame, showing the crack on the downtube just behind the headtube:
That crack goes almost all the way around the tube, but about 1 inch is still intact. I will be looking into whether it can be fixed by Calfee. Sad.
Hey, an update: Calfee just got back to me and said the old frame "is indeed fixable," so I'll be dropping it off as soon as I can get down to Watsonville. Glad!
