I have a 2013 3, the red one and transferred a topeak explorer from my hybrid with no problem. It was designed for disk brakes and is bowed out to fit around the discs on my hybrid but since Salsa cleverly puts the brake setup out of the way in the rear triangle the rack sits out further than needed. My Axiom panniers fit fine but haven't done a loaded tour yet, just groceries so far. That rack was only about $45 as I recall.
