I'm going to be there driving 20 hours one way friday and 20 back sunday. How is the seatpost attached? See you at the show.
The post is a rare Campy Super Record model, made during the Moser aero era. The slanted bolt is captive and thread through a long aluminum rod. turning the bolt moves the rod uphill, following the angle of the bolt. As it travels up, it pulls on a wedge, much like a quill stem.
