Metal HIC Kits are among the most reliable. Time and time again I have experienced first hand the troubles of using a plastic compression kit. What makes this one even better is that it has a removable top piece. What this means for riders is that you can use it even with scooter forks that have a much bigger threading and compression screw such as some forks made by Ethic, Urban Artt and Flavor pro scooters to name a few.
