A compound bow comprises at least one limb that extends continuously between opposed rotatable members. In some embodiments, the bow comprises a second limb that extends continuously between the opposed rotatable members. In some embodiments, the limbs are parallel to one another.

In some embodiments, an archery bow comprises a riser and first and second limbs. The first limb supports a first rotatable member, which is arranged to rotate about a first axis. The first rotatable member comprises a bowstring track and a cable track. The second limb supports a second rotatable member, which is arranged to rotate about a second axis. The second rotatable member comprises a bowstring track. A bowstring comprises a first wrapping portion, an intermediate portion and a second wrapping portion. A power cable is arranged to contact the cable track in at least the drawn condition. A separation between the first axis and the second axis in the brace condition is at least 27 inches. A length of the first wrapping portion is at least 52% of a length of the intermediate portion.

A projectile launching device includes self-timing without cam lean. The projectile launching device may include a rail, a riser, two energy storing components, (such as two limbs), two cams, a launch string, and at least one cable. The ends of the launch string are attached to the two cams. Opposing ends of first and second cables may be coupled to the rail or riser. A mid-portion of the first and second cables are slideably engaged with the first and second cams, respectively. Alternatively, a single cable may replace the first and second cables. The two cams are preferably built as mirror images of each other at a centerline of the rail. The two cams include a launch string track, having identical, but mirrored, upper and lower cable tracks.

A monitoring system for an archery bow is provided. Monitoring devices and methods are also provided.

In some embodiments, an archery bow comprises a riser and first and second limbs. The first limb supports a first rotatable member, which is arranged to rotate about a first axis. The first rotatable member comprises a bowstring track and a cable track. The second limb supports a second rotatable member, which is arranged to rotate about a second axis. The second rotatable member comprises a bowstring track. A bowstring comprises a first wrapping portion, an intermediate portion and a second wrapping portion. A power cable is arranged to contact the cable track in at least the drawn condition. A separation between the first axis and the second axis in the brace condition is at least 27 inches. A length of the first wrapping portion is at least 52% of a length of the intermediate portion.

A compound archery bow includes a pulley member that is rotatable on a transverse axle and that takes up a power cable as the bow is drawn. The pulley member is arranged so as to be fixed at any one of multiple transverse positions along its rotation axis relative to the bow limb by one or both of: (i) the transverse axle being retained on the bow limb at any one of multiple axle positions along the rotation axis by engagement of the transverse axle with the bow limb, or (ii) the pulley member being retained on the transverse axle at any one of multiple pulley positions along the transverse axle by engagement of the pulley member with the transverse axle. Performance characteristics of the bow can be optimized with respect to the transverse position of the pulley member along its rotation axis.

A compound bow comprises at least one limb that extends continuously between opposed rotatable members. In some embodiments, the bow comprises a second limb that extends continuously between the opposed rotatable members. In some embodiments, the limbs are parallel to one another.
