I mentioned this in the other thread in Bike Mechanics, but I don't think this frame is a Trek 560 Pro. Firstly, it's the wrong color. The 560 Pro is "Aqua" or orange for this year. You can see it right in the catalog linked at the top of this thread. The 560EX was grey, but had black faded in on the bottom. You can also see that the rear triangle and front fork have eyelets, which Trek race frames should not have. It seems to me that someone migrated the 600 components over to a Trek 520 frame.

Can someone verify this in case I'm talking out my ass?
