A 52mm chain line seems to be the “standard” for bikes with boost spacing. For some reason Giant speced the fathom 2 (praxis crank) with a 0mm offset ring which makes it a 55mm chain line. The 3mm offset ring brings the front chain ring 3mm more inwards which makes the chain a little more straight when you are in your lowest gears (biggest cogs). The fathom 1 comes with the SX crank comes with a 3mm offset ring.Excuse my ignorance, but what's the offset chain for? Also, what grips did you swap out too? I feel the ribs on the stock Giant ones are too soft for me. The ribs move under my ha d too much.
