Ask ScooterDad: Why do bars need slits and what do slits really do? Are they necessary?

Answer: 

If you have an external clamping mechanism (ICS, IHC, HIC), then you need a slit in your bars. Without the slit, the bars will resist compression and the clamp will do nothing to squeeze the bars against the fork or shim. The slit allows for compression of the bars. This is not true with SCS as you want the bars to be solid and resist compression since there is nothing inside the bars.
