Carbon Seat Tube - Post minimum insertion
Hi,
Quick question, i have a 2011 Wilier Izoard XP with the original Alu Deda seatpost. I'm just curious, the minimum insertion mark on the seatpost i assume is just for the post. Is there a minimum insertion for the frame? The reason i ask is that thinking about it, the frame must get stressed differently during riding when there is more post or less post in the tube (with front-back and lateral movement). The seatpost is like a lever i would say, clamped at the top, but the bottom surely moves about the clamp which is it's axis, right?
Has anyone ever heard of a carbon seat tube cracking or anything due to too little seatpost in it?
Thanks!

As long as the bottom of the post extends past the bottom of the junction between the top tube and the seat tube, you'll be fine.0
