I have a short, fluted NR seatpost with no minimum insertion mark. The post is a little over five inches long and if I insert it more than an inch and a quarter into the frame, the flutes start to disappear. Plus, I need a little less than four inches to get proper saddle height. So, is about 1 1/4" enough insertion for safety? I really don't want to have my rear wheel inserted into a part of my anatomy I consider "exit only".
1.25 inches into the frame? It sounds like you have one of the older model seat posts, where the riders would ride on huge frames and seat post length doesn't really matter. I would honestly give it 2 inches instead of 1.25, as I have seen people put in about that much into their frame, and the paint start chipping off of the seat tube from the seat post adding pressure from the inside. But, I know little of bikes in general.
