I've experienced that very short* inline seatposts made from alu can cause a lot of pain. Could it be that the Trek has a way shorter seattube that allows more flex and forgiveness?
*not a lot of post showing above the top tube.

I’m thinking this too, it would have gradually get worse, rather than immediately flared after a few minutes.
Maybe try the lightest flexiest post you can get your hands on or try doing some drillium on a cheap post?
