LIGHTENED AND BALANCED CRANKS
APE completely machines the crank counter-weights
to remove weight and narrow the pro le (sometimes called “knife-edging”.) The oil holes are  uted on certain models to keep more oil at the bearings. The crank is then balanced on a state-of-the-art computerized balancing machine to extremely tight tolerances.
As all racers know, heavy wheels and brakes spinning fast act like gyroscopes, and resist being moved o  their axis, such as leaning the bike over for cornering. Same with the crank. The heavier the spinning crank, the more it resists being tilted when cornering. Light cranks not only make more power, but help improve handling.
