The ITM Visia stem is one that came with the bike. It's a 90mm and I'm looking for a 110mm.
I was considering the FSA Carbon Pro stem- decent price and looks like carbon to match the rest of the bike, but I'm concerened about the angle. I wouldn't mind even if it were to angle down a bit, but it seems that w/ the 6° angle it will always angle up. I guess that's why Orbea specs ITM.

Thanks to everyone for confirming my assumptions here!
