If you run HIC compression, you need the Lucky HIC Compression System. HIC compression is a favorite of pro riders because it is inexpensive and simple to set up, emphasis on inexpensive. The HIC shim simply screws into the top of your HIC PRO SCOOTER FORKS via the supplied compression bolt, which makes it possible to run oversized bars with a slit and an oversized clamp.
