Compression Systems Explained
Compression Kits are required when using threadless forks on a scooter setup.
There are 4 main types of compression available
1 Standard Compression System (SCS) An easy to install clamping system that provides an external component (SCS Clamp) to clamp the bars into the top and bolt the forks into the bottom.
2 Inverted Compression (ICS) - A starnut Installed in the Bars and a compression bolt (either long or short dependent on forks) is then screwed up through the forks into the starnut
3 Hidden Internal (HIC) A starnut Installed into the Forks and a compression bolt is then screwed through the headset and use's a sleeve into the starnut located in the forks. This system requires HIC bars to fit which are larger in diameter to fit over the sleeve.4 Integrated Headset Compression (IHC) Similar to HIC but standard bars are used not over sized HIC Bars
