SCS - This is the standard compression system. This system works by entering a star nut into the top of your forks, a bolt is placed through the spacer which sits on a lip inside the SCS and is tightened down. The bars are then place into the top of the SCS and tightened. You must not have a slit in the bottom of your bars for this system. You can cut your bars down by around 1/2 inches as using this type of system makes you bars 2" higher any way.
