I've got a 63cm C50 and wondering how long of a post I need to be safely within spec. A 270mm post only gives me about 20mm of post below the bottom of the top tube, which is still pretty far above the bottom of the lug. The min insertion mark is a good 20mm inside the frame, but doesn't Colnago warranty require something like 200mm inside the seattube? I'm 185lbs, so I'm not worried about the post as much as I'm worried about force being transferred to a single spot in the middle of that lug instead of spread out throughout the lug joint. Any thoughts or advice? Or should I just suck it up and go find a 300mm carbon post?
