BA began by painting his standard AF1 66 trucks by hand to get the custom colorway exactly as envisioned. Take notice to the red "ACE" logo and black checkers on the baseplate, two rare touches. Looking for a slight increase in weight, and also add a unique touch, the hanger is painted cream then black, with the cream base layer revealing as the black coat is skated off. The "BA" moniker is embossed into the hanger opposite the size marking. Dubbed "Street Pirate" by Frank Gerwer, this namesake is engraved into the axle.
