Thanks! Seatpost is a bit lighter and the smaller diameter has some give to it, plus I had it laying around. It's an older Shimano PRO Vibe 7s post. Wheels are a little lighter, I could go lighter but these are bombproof. The hubs are better and already broken in. Plus the tires are more road oriented, the main difference is it's easier for the bike to hold 46kph thus giving me a little more range. Not needed, but I like parking it as fast as it'll go on my way to the shop
Converting would be pretty easy with a couple moves. The main challenge is you've got to replace the rear derailleur, Shimano mountain and road derailleurs and shifters have different cable pull ratios. Additionally you want to note which calipers and brake hoses you use, sometimes there is a road drop lever that can work with that system which lets you just replace the shifter/master cylinder versus the entire brake system. GRX stuff is totally rad and would work well, same thing Spec. uses on the Creo. Both the flat bars and 99% of road bars have a bar clamp diameter of 31.8mm, no issue switching over.
