SCS, HIC & ICS Compression systems
Compression is the system that keeps your headset tight and secure. There are three mail types for compression.
- SCS - Standard Compression System
- HIC - Hidden Internal Compression
- ICS - Inverted Compression System
SCS and HIC are similar in the sense that a starnut is installed into the fork. ICS is unique in the sense that an oversized star nut is used and install into the handlebar. All these compression systems use bolt to pull the star nut in and bring tension on the headset.
