Pioneering Stabilizer Innovation

When Pioneer Archery Designs develops a product for RamRods, we follow a fourteen step development process that includes three separate testing and evaluation phases. The RamRods archery stabilizer system has gone through three different carbon fiber layups, three different end cap designs, and more than 200,000 shots in testing by several of the best recurve archers in the United States to get to this point. In this first full-scale production release of the RamRods archery stabilizer system we have brought several innovations to the table.

 

Changing what you know about stabilizing your bow.


When you think of the bow, think of it as a complex system. This complex system includes everything the archer attaches to the riser- sight, limbs, string, rest, plunger, dampers, stabilizers, etc. These parts should all interact to help the archer to shoot consistently. The stabilizer system operates within this system and it serves two purposes:

  • help the archer hold the bow steady so they can aim
  • help take excess post-shot vibration out of the system

When you select stabilizers for your bow, you should be asking how the stabilizers you’re about to buy are going to help you achieve these two goals. First things first, let’s debunk the myth that a stiffer stabilizer is better for everyone. The stiffness of an object is defined as the measure of the resistance the object offers to deformation. For stabilizers this stiffness can be found by applying a force (weight) to the end of the stabilizer and measuring how much it bends under that weight. This amount of bend is known as deflection. By dividing the amount of force applied by the deflection, you can find stiffness. More weight will cause more deflection. This means that the more weight an archer uses on the end of their stabilizer, the stiffer the stabilizer will need to be to support that weight. This stiffness of a stabilizer can be increased by using a higher modulus carbon, by changing the orientation of the carbon fibers, or by using a shorter version of the same stabilizer. It will be decreased by using lower modulus carbon fiber, through changing the orientation of the fibers, or by using a longer version of the same stabilizer.

Your next question may be, “Why does it matter how much my stabilizer bends?” The answer is somewhat complex. Every object will respond by oscillating at a certain frequency when a force is exerted on it. The resulting frequency is dependent on the amount of force exerted as well as the stiffness of the object it was exerted on. This is why a stiff stabilizer with a not enough weight will produce a “buzzy” feel after the shot and a weak stabilizer with too much weight will produce a “floppy” feel. So realistically, your stabilizer selection should depend on how much weight you plan to use. Don’t buy the stiffest stabilizer on the market just because it’s supposed to hold better unless you plan to use a lot of weight.

We designed the RamRods archery stabilizer system around a recurve archer that will shoot between 3 and 10 ounces of weight on their front stabilizer assuming they use dampers on at least their side stabilizers. In the last two paragraphs we stated that the stiffness of an object is dependent on its length and that the frequency it will produce is dependent on its stiffness. Our side rods take that into consideration. A side rod is, at most, half as long as a long rod. This means it is at least twice as stiff. This doesn’t really make sense because a stiffer stabilizer needs more weight than a weaker one, and a recurve bow is supposed to balance front heavy. That is, it’s supposed to have more weight on the long rod than the side rods. To get around this, the RamRods archery system uses a different carbon layup in its side rods than it does in its long rod. This design offers a soft, but not floppy, feel when properly set up.

 

The evolution of the end cap.


The distal end caps on the RamRods Archetype stabilizer system are precisely machined out of stainless steel and weigh in at 1.8 ounces. This weighted distal end cap gives the stabilizer an overall front-heavy balance and reduces the amount of weight the archer needs to mount to the stabilizer. This is important in windy conditions when any added surface area can make it harder to hold the bow steady. Our uniquely designed distal end cap also gives the archer the ability to shoot ANY weight that is threaded for either 5/16″-24 or 1/4″-20 by means of interchangeable threaded inserts that come with each stabilizer.

The proximal end caps of our stabilizer system are precisely machined out of aluminum and weigh 0.7 ounces. They contain almost an inch-long threaded segment and are designed to eliminate the need for an eye bolt. The Archetype proximal end cap also has an unthreaded through hole that will allow the archer to apply more torque when mounting their stabilizers.
