The Importance of Parallel Cam Technology

If you shoot a compound bow, you probably have a fair idea of how it works. But did you ever wonder what critical role the cams play in the shot process? What’s more, have you ever weighed the pros and cons of different cams, including parallel cams? If not, here is your quick guide on bow cam technology.
Traditional recurve bows get harder to pull the further you draw them back. That’s because the energy is being stored in the limbs and reaches a critical point where it cannot hold any more. Cams reduce that burden by manipulating the draw weight mechanically so you don’t feel as much of it. Instead of getting more difficult at the end of the draw length, camspeak in difficulty somewhere in the middle of the draw and then let off again. This can be visualized by a graph showing the draw length versus the draw weight. The area below the line represents the potential energy of your bow (aka, how fast it can shoot).
