ABSTRACT:
A tiller adjustment system for an archery bow includes a tiller adjustment knob for precisely adjusting the tiller of a bow limb. A locking mechanism secures the tiller adjustment knob in place to ensure that the precise tiller adjustments are not disturbed, even when the bow is broken down for travelling and storage. A specialized spacer with a curved top surface is disposed within a similarly curved ceiling of an internal cavity formed in the tiller adjustment knob. In addition, a biasing mechanism in the form of two spring steel members are positioned in the bottom of the limb pocket to urge the bow limb into engagement with the tiller adjustment knob.
