• It's an XT-M786 mech, XT 780 shifters (both 10 speed).

    Chainline is good, 45-46mm. It's a triple crankset, so the chainring is effectively where the middle ring would normally be. I just used a 5mm narrower bottom bracket than Shimano specified, because the rear frame spacing is 130mm (vs the 135mm MTB spacing they specced it for).
