## Discrepancy

(CAN) THE WHEEL IS THE OLDER THREE-PIECE TYPE. SEVERAL CRACKS WERE FOUND IN THE ALUMINUM CASTING AT THE FLANGE RETAINING BOLT HOLES, WITH SOME HOLES HAVING CRACKS THROUGH TO THE OUTER CIRCUMFERENCE OF THE HUB AS WELL AS ALONG THE SPOKE. ALL CRACKS WERE APPROXIMATELY ALIGNED WITH THE BOLT AXIS.
