The Piper Superlite Wheels 4pk is tuned for max speed and minimum weight. Built from Piper's signature racing formula, these outdoor wheels feature an ultralight built that speeds things up without weighing your feet down. An internal nylon core keeps things light, while a 78A hardness provides plenty of cushion to handle debris and rough surfaces with ease. A 65mm wheel height delivers speed you can feel right away, while a thinner 38mm width allows for high maneuverability.
