Lucky ProBars™ come in both standard 1¼” as well as over- sized 1⅜” with a cross-bar and no back sweep. Oversized Pro- Bars include an innovative com- posite HIC shim (that does not re- quire a top cap) that protects the bar and buffers vibration. They are designed to fit on threadless forks with HIC. The standard-sized ProBar fits a Razor Ultra Pro, MADD, or any scooter with a threaded fork; however, the oversized version is not designed to fit on a stock Razor scooter or any other scooter with a threaded fork. Bolt and star nut are included.
