The AeroBump™ String stop


What do string stops look like today?  In terms of material, a good string stop involves a lightweight rod connected to a piece of rubber.  Examples of that "lightweight structural material" include a bent rod made of aluminum or a straight rod or tube made of graphite or carbon.  And, finally, usually, those rods/tubes are attached to one's bow by one or multiple set screws.

For the AeroBump, we take all those notions and flip them on their heads.


Product Details

Now that we know what string stops are usually like, its important to understand that the main problem that arises with traditional string stops can be described in one word: vibration.  The cause of this problem however, is multi-faceted.  The table below attempts to organize how and why vibration is precipitated and how the AeroBump can alleviate or even completely eliminate that vibration.

Problem Solution(s)

Aluminum, graphite, or carbon all have a vibrational energy output of up to 98%.

Titanium, on the other hand, actually consumes energy due to its ultra-rigidity.  More specifically, AeroBump's main component is made of GR2 titanium, the most pure grade.


The bent or straight design of the rods/tubes do little or nothing to mitigate the vibrational energy output of the string stop to the bow. 

Our Z-bar is designed, as its name suggests, in a "Z" shape to further eliminate any of the already reduced (via the titanium) vibrational energy.  This is possible due to how it allows the rubber bumper to be closer to the center of the bow, which enhances its ability to halt the string.


The set screws used to unite the rod/tube with your bow amplify the vibrational energy because they act like a stylus or focal point for energy to build.

AeroBump's Z-bar has machined 5/16"-24 threads at its riser connection end and utilizes a custom GR5 titanium nut to remove the possiblity of energy promotion.
