I converted a Trek CrossRip into a 1x flat bar bike. It was a drop bar 2x, rode nice, but I was using it as a commuter and I liked a more upright position better for that scenario.
I put a carbon seat post and carbon bars on it and it really made the ride very comfortable, and I got the total weight down to about 20 lbs. I changed jobs and ended up selling it when the lack of bikes was heavy as I no longer needed the commuter.
