The HD is designed for demanding riders that bend any deck. AO increased the thickness of the center beams by 30% making it significantly stronger. Unchanged are the Stealth’s amazing riding and grinding capabilities which are supported by an all flat deck, grind rails to reduce friction and rounded edges to prevent injuries. It comes with an indestructible high tensile axle bolt, steel flex brake and the head tube opening is machined after anodizing for a tight fit of the headsets. The brake is adjustable and fits wheels from 110 to 125 mm.
