Aluminum frame, carbon fork and seat post.
Brand new selle Italia saddle. (Not in pic)
Fancy giant wheels: P-SL0 Alloy Road WheelSystem (WheelSystems) - Bike Gear | Giant Bicycles | United States
Dura ace 9spd groupset with ultegra brakes.
Cassette, chain and big ring all new this passed season, couple marks on the clear coat of the aluminum, but overall it's in pretty good shape.
$850.
$600 with stock wheels.
$925 if you want the trainer too (cycle-ops)
This is the only (crappy) pic I have of it.
Edit: it's a medium/large with a short stem. I think that translates to 55cm, I forget. I'd say this is suitable for anyone from 5'8" to 6' with minor tweaking. 175mm cranks.
