Tear up the vert while remaining flat spot free with a set of Ricta Sparx 54mm 99a skateboard wheels. These 99a rated wheels are a great mid range of grip and slide for control on vert when you want, but premium power slides when you want as well. The 54mm sizing offers above average carrying speed to maximize your pumps when riding vert and help with ease on and off of coping. The larger wheel size is also great for street riding so that every grain of sand doesn't take you out.
