This is old Trek Madone 5.2 (2006) with the unloved aero-seat tube with stock Bontrager Race-X-Lite fork. At least mine is with "unique" seat tube.
When engine/I get better, I'll swap the parts onto better frame and fork (had found good deal on full DA7900 build kit with wheels). Or if engine really that better I'll just get whole new road bike and make this my backup.
Frame is 58cm
Full DuraAce 7900 group with Gore RideOn cables
Easton EA90SLX wheels with Conti 4000s tires
3T ARX stem
3T Ergonova Team bar
Selle Italia SLR gel flow saddle
Ritchey carbon superlogic seatpost
Arundel chrono cage (aerobottle left off pic)
Cateye V3 cyclometer
total weight as pictured 16.7 lbs (certainly no weight weeenie but ok for low-end frame)
