Thanks for the explanation walks with a gimp. If I understand this right the bus cable is what hooks the cams to the limbs. In a dual cam bow there are two of these cables and if they strech a different amount the cams will be out of time. The cam and ahalf only have one buss cable if it streches both cams will move the same amount . this will put them in the wrong position but they will be in time with respect to each other. Am I close?
