This Apex HIC compression kit set is designed to work with threadless pro scooter forks with threadless headsets and oversized scooter bars. The kit includes a 2.1" high shim, oversized double clamp, and 25mm long metric 6 allen bolt. If you order this set together with a threadless fork that does not have metric 6 threads machined in, ask us, and we will install the star nut for free. Please read instructions before ordering.
Tools: Allen wrench metric # 5, Star nut setter (steel forks)
If your pro scooter fork does not have metric 6 threads machined in the top of the steerer tube, install starnut in fork steerer tube using a star nut setter. If you have an aluminum fork, you may need a 1 inch star nut. Install the fork through the headtube. Install top headset bearing, compression ring and headset cap. Make sure you have at least 1.5 inch but no more than 1.8" of steerer tube above the headset. Slide HIC shim over steerer tube. Place cap on top of shim. Tighten cap down with the compression bolt and a # 5 allen wrench until headset feels solid (no play) and still turns smoothly. Slide oversized pro scooter bar over shim and clamp it.
