The riser (the centre section of the bow) is generally separate and is constructed from wood, carbon, aluminium alloy or magnesium alloy. The term 'riser' is used because, in a one-piece bow, the centre section rises from the limbs in a taper to spread the stress.
You actually keep twisting it and then string the bow to see if you've reached the recommended brace height (the distance from the string to the deepest part of the riser), usually the distance is 7 3/4 inches to 8 1/2. You should look online for what the recommended height is.
