Engineering problem:

Road bike, Audax Aluminium frame + Ali seat-pin.

How many diameters minimum in the frame for safe and secure operation, taking into account the number of diameters sticking out?

Opinions?

At least 100mm odd, and the seatpin should extend well below the tt/st join.

Most posts will have a minimum insertion mark on anyway...?
