Since you are in the looking stage maybe consider a 2x chainring
The bb change makes sense. The q factor doesn't bother me. I haven't looked to see if the SRAM GX crank is direct mount, but would consider something like that.
I haven't really considered a 2x, would that work with a SRAM 11-42 cassette? Just looked at the Rival 22 crankset, lowest gearing offered is 46/36. Could I change the 36 to a 32?
