How can I tell a Giant TCR Alliance 0, from a TCR Alliance 1, or a TCR Alliance 2?
The frame seems to get good reviews, with composite use of both of aluminum and carbon, as described on the Giant site.
Interestingly, it has Dura-Ace derailleurs, shifters, brakes, and crank, a Thomson seat post, an FSA headset, a Chris King front hub, and a Dura-Ace rear hub. Was that a set that was ever standard on an Alliance, or has it been modified/upgraded?
This is the only pic I have:
