Another thing to note is I believe my chainline is further out away from the frame, haven't measured anything yet because my old crank is at my work but looking at the bike when its in the 52 up front and 28 in the rear, it looks like the chain is at much more of an angle than I ever remember seeing with the FSA. According to the spec's, the FSA has a 44mm chainline and the Shimano has a 43.5 so would the Wheels bottom bracket conversion come into play here? Don't think so but today I noticed when I was pushing hard I could feel the chain rolling, kind of a rough feeling throughout the bike that wasn't there before.
I have cross chained my previous setup without issues for three years and the chain is brand new.
