Due to the ideal construction the mass distribution in the riser, the center of mass and the center of force, named pivot point, are closer together than in any other riser on the market which we know.
With the special bare bow accessory weight, the center of mass is shifted towards the front of the riser and below the center of force. Depending on the mass of the used limbs, the bow nearly or even completely looses the tendency to roll backwards after release and it stays calmly in a vertical position.
All this guarantees maximum precision during the shot.
You can watch this effect fantastically in the direct video comparison between the two female bare bow finalists at the Italian indoor championship 2012. The later winner shoots with a (slightly too long) bow system with Black Thunder ILF.
