It's a racer's build. Fine for it's intended purpose. Go for 100-120mm fork if you want it for other use... I run a Rev spaced down to 120mm and it's just right as an all-round XC bike.

Australian spec Anthems came with 100mm forks, US spec came with 80mm. A 100mm fork will slacken up you head tube angle by something like .5 degrees. I have an Aus Spec with Fox 100mm fork. I've been told with such a steep head tube angle the bike can feel twitchy. After riding and racing the bike for the last 6 months it does not feel twitchy. What it boils down to is the bike goes where you point it weather that is where you wanted to go or not, most casual riders do not like this level of responsiveness. I think that is the main reason that Giant slackened the head tube angle on the AnthemX.
