The KIZER Fluid IV Superfluid could be the best anti-rocker frame on the market for aggressive skating. Designed as the ultimate aggressive frame for all types of grinds, the frame is lightweight, super durable, and glides on all kinds of surfaces—from rails to coping, marble, and even rough concrete curbs. The brand new Superfluid material can withstand a lot of abuse while gliding perfectly over all materials and obstacles. To enhance control, the KIZER Fluid IV Superfluid features a unique groove shape that leads directly to the anti-rocker wheels, resulting in a perfect lock-in and fast, fluid sliding. This lightweight frame accommodates wheels up to 60 mm on the outside and standard anti-rocker wheels on the inside, providing maximum roll speed and minimal height to improve balance and stability. To fit different shoe sizes, the KIZER Fluid IV is available in three different lengths. The frame includes double steel axles and aluminum spacers to ensure your wheels spin faster and last longer. The Fluid frame family has been a popular anti-rocker frame among aggressive skaters for years, and the KIZER Fluid IV enhances what is already a great collection of frames. Try it out for yourself.
