hey, it's your bike... i rarely see those here in Podunk, Oregon.
the pressfit treks, and a few other brands, are known for sloppy/creaky BB behavior.
a bearing might be loose in a cup too.

it sure sounds like a der. cage rubbing on big ring teeth to me... as mentioned by delbiker too. the left downstroke fits that too, if you add a tiny bit of flex or a loose bearing....
