The Kizer Fluid IV Grey frame is the world's first 100% anti-rocker frame on the aggressive skating market. These classic UFS frames are optimized for grinds in every aspect. The infamous Fluid material will withstand any abuse while sliding perfectly on all materials and obstacles. The unique groove shape leads directly towards the anti-rocker wheel, resulting in a perfect lock & slide feeling. This lightweight frame holds two outside wheels up to a wheel size of 60mm, providing maximum rolling speed at minimum height. To match your personal shoe size, the Kizer Fluid IV comes in three different lengths. Solid Kizer double steel axles & aluminum frame spacers will make your wheels spin fast for longer. Thanks to the UFS mounting system, the frames fit perfectly on all UFS-skates available.
