    Hooded dropout rotational orientation?

    Complete greenhorn here! Couldn't find the answer after some digging so asking for help. I am using Paragon's hooded rear dropout (thru axle - DR2065). Is there a correct rotational (around axis of axle) orientation for installation? I know I need to keep left and right dropouts in phase with each other. Thinking in terms of resulting angle of derailleur hanger and how important that is. I see on their drawing they show 128 deg and 61 deg indications. Thanks for any insights or suggestions! Daniel

    The top plane from the model should be aligned with the bottom bracket for 10mm hanger setback. For 8.5mm (preferred), 3 degrees of rotation above the bb.

    Thanks, PVD, for the input. Is the setback a measurement from the vertical? This is my first frame, so all of this is new to me.

    Setback is the distance from the plane perpendicular to the plane formed by the rear axle and bottom bracket spindle. The length of the hanger and set back are specified by SRAM and Shimano.
