Sometimes you can find a work around and rig an ill fitting rack...but personally i would return it to Amazon rather than force something. I also have the Giant Escape 2. I bought the Topeak super tourist tubular bicycle rack off amazon. Fits perfectly. They have disc & non disc versions. I have rim breaks, but i know the newer Escapes come with disc brakes. So you’re covered either way. I got a topeak bag which slides into the rack, but will also add ortlieb panniers on the side for more storage.
