Set with 4 different lengths of headset spacers (3mm, 5mm, 8mm, 10mm).
Used for compatibility issues when:
- The Shim is too short to reach the headset.
- the fork hits the SCS system so the compression bolt cannot be tightened.
- If you have a Madd deck and want to upgrade with a Lucky SMX for and HIC / SCS system.
- If you have a Blunt Envy AOS V2 deck and want to use it with a HIC / SCS system.
Put these over your headset, on the fork and create the needed space.
