Cervelo P2 seatpost...minimum insert length?

Does anyone know the minimum amount the carbon cervelo seatpost on a P2 has to be inserted? I don’t see a mark or line…I think it’s worn away or something.

Thanks!

2 inches on all carbon seatposts.

I may be way off but I thought I heard that you need a minimum of 5-7cm below the clamp for safe riding. It may be different with aero posts, but I would definitely recommend more than 4cm no matter what the accepted minimum is. Even that may be pushing the lower limit.

2 inches = 5.08 cm , at least by my bad memory.

65mm

65mm

My GF says no less than 205 mm.

If you have to ask, your seat is too high.
