Trinity Ninja 4x90mm 273mm black Size:273mm Basically ABEC is a ratingThe Trinty NN 90 is the most nimble 4 wheel frame of the Trinity NN Family. It's agile while maintaining speed and stability for the ride experience. Normally, skating a longer frame will feel like you're rolling on rails, but with the custom "V. m" rockers, the 90 turns like a dream. Combining Powerslide's proprietary Trinity mount with NN's custom "V. m" rocker, you can't go wrong with the all around "ninja" while you're skating all around town
