Simple tools and a good eye are all that are needed to work out the possible fork misalignment.


A straight rod about the same diameter as the drop out slot fitted into the slots serve as a straight edge indicating the dropout end of the fork. A second straight edge placed across the tops of the upper legs, just below the crown, does the same for that end of the fork. Are the two edges parallel when viewed from above?


A good dished and true wheel placed fully in the drop outs (without clamping any QR as that can shift the wheel) serves as a indicator for the "blade" lengths being the same. If the rim is off center near the top of the fork then the wheel is situated off plane from the steerer.


Sighting through the steerer (star nut and any other inside the steerer part removed), through the above rim's valve hole (is this hole centered in the rim?) to the bottom of the rim (opposite the valve hole) and seeing if this view is centered on the rim will indicate if the fork is splayed to one side or the other.


Creative people will come up with refinements of this but this is very basic 3 axis aligning checks stuff. Andy.
