An archery bow includes a riser, a cam module rotatably mounted to a fixed pivot supported by the riser, and an energy storage system comprising at least one axial tensile spring operatively coupled to the cam module via a multi-roller shuttle assembly. The cam module includes a cam track with a variable slope profile that governs the draw force curve during rotation. The multi-roller shuttle assembly engages both the cam track and a guide track surface to constrain the shuttle to a defined path, thereby elongating the axial tensile spring as the bow is drawn. The cam module includes parallel string grooves for engaging a single bowstring without synchronization cables. The axial tensile spring may be folded around a turning element to form two tensile legs and housed within the riser. This configuration enables compact, lightweight bows with customizable draw characteristics and reduced lateral torque.

A set of archery cam devices for an archery bow is disclosed herein, including first and second cam devices configured to be rotatably coupled to first and second limbs of an archery bow, and having first and second bowstring sheaves, first and second control sheaves, and first and second power cable sheaves. When the archery bow is vertically oriented: a vertical riser plane extends through the riser ends; a vertical bowstring plane extends through the first and second bowstring sheaves; a vertical control plane extends through the first and second control sheaves; first and second vertical power cable planes extend through the first and second power cable sheaves; the vertical bowstring plane and the vertical control plane are located on opposite sides of the vertical riser plane; and the first and second vertical power cable planes are located on opposite sides of the vertical riser plane.

An archery cam adjustment assembly for an archery bow includes an axle extending along an axis from a first end to an opposing second end and structured to traverse a limb of an archery bow. The axle further includes a central portion defining a plurality of threads. A cam support is structured to support a cam and to engage the central portion of the axle. A securing member is structured to be moved between a locked and an unlocked state. In the unlocked state, the axle is enabled to rotate freely relative to the cam support to move the cam support along the axis and displace the cam in a lateral direction with respect to the limb. In the locked state, the axle is inhibited from rotating relative to the cam support and the cam support is inhibited from moving along the axis.
