• Even if my shit old measure was out by .5mm, still doesn't explain why the bb axle sits at the wrong depth

    If your axle really was 13mm minimum across flats, the crank would be pushed out about 9mm. The error on the axle width is multiplied by 28.6 (i.e. 1/tan2°) as an axial displacement of the crank.

  • I'll throw the shit caliper in the bin. It was in the bottom of the toolbox for a reason.

    Maybe @JWestland is right, that the angle of the tape isn't the same as old ones...

    So, considering that a crank sits barely 50% onto this axle, and now ignoring my shit earlier measurements, should I just mount it? Is this standard?
