Nice looking bike on paper, I really like the triple. The wtb rims are user friendly for tubeless setup, you'll just have to wait till you get it to see what it comes with however they probably ship it with tubes and you will need to tape up the rims, install valve stem and air up yourself.
The pedals might need replacing but that depends on your likeability. My rule for upgrading is ride it stock until you figure out if a part needs replacing. I try not to upgrade for upgrades sake and replace a part when it will improve comfort performance or I want to change the character of the bike.
but because i weigh 240 and plan to always have gear on it i needed a triple with hydro brakes, and it seems like a way better deal to me the one i got.
I can eventually make the one i got to the level of the other one for less it just apealled to me deal sense more
