I have a 3T Doric seatpost. On my new frame its a bit short since I previously cut it.

The height I need it at, I checked and it had about 1” inserted into the frame.

Is that not safe?

Not safe. You need around 100mm of insertion.

Uh, nope. I’d want at least 10cm.

Yeah. The safety issue is on both the seatpost and the frame. The minimum insertion helps distribute the load on your bike's seat tube. A too short of a seatpost inside the seat tube can cause the seatpost to break. Some frames manufacturers will deny a warranty claim if they suspect too short of a seapost was used.
