ILF stands for International Limb Fitting system. ILF risers and ILF limbs follow an agreed global standard and are compatible between manufacturers.
Most ILF bows allow some form of adjustment of draw weight and tiller. Some even allow for adjusting the centre line of the string.
We made a short video that shows how to adjust the tiller of an ILF Black Hunter riser. To adjust the draw weight simply do the same amount of adjustment on both bolts.
