One thing to remember: these are two amazing bikes, and you’re going to be happy either way (especially coming from a road background).
The epic is an insanely capable race bike.
The EVO is an insanely race-able trail bike.
Choose one and never look back.
One other thing. I’ll never again ride an MTB without a dropper. If I were to get the epic over the Evo (definitely possible) I’d add a dropper before I even picked it up from the shop. Just my two cents.
