Can you explain what the FCS does?

FCS (Feeling Control System) is an adjustment which changes the contact point in the lever stroke (i.e. lever travel). This adjustment gives the rider several advantages; including the ability to select the contact point according to their personal preferences and not some predetermined contact point selected by the engineer. Also, it allows the rider to adjust the both the left and right levers to contact at the same location on each side. We designed the adjuster so that it is tucked away behind the lever blade and out of harms way during crashes.
