Monkey Barrel 5a counterweight


The new monkey barrel counterweight has some classic features that you will find in the market today. Delrin body, friction fit bearing, and an end plug are standard. We used an extensive prototyping process to refine the shape to be large enough to make an easy catch and kept the edges smooth to ensure comfort. The friction fit bearing and plug all assemble into a classic-looking counterweight. That is where the similarities end.

Using the same technology we used in our Private Reserve begleri, our new counterweights use our proven Control Rod Technology (CRT). This system lets the player fine-tune their weight to exact preferences. As your skill progresses, so too can the counterweight. There are eight machined holes on the bottom of our design. Four of these holes are added to keep the initial weight down, while the remaining four are machined to accept our one-gram control rods, thus letting the player adjust the weight to their own skill and comfort levels. At release time, stores will have the option of white, Black, Red, or blue. Later releases may involve other colour options. Each counterweight will ship with the body, top plug, a bearing, 4 x one gram control rods, and a hex key.

The base model weighs only 10.6 grams.  Having a height of 21mm and a diameter of 24mm the monkey barrel is perfectly contoured to fit your palm and make easy grabs.  Each Barral has 4 weight-reducing holes and 4 threaded sockets for the CRT system.

Over the past few months, many yo-yo companies and people have produced new designs for counterweights. Now that the 5A patent restrictions have been lifted, I suspect that this style will finally flourish with new ideas, designs, and innovations.

The learning curve for 5A is a steep one for many throwers, and as they progress, they will look to change their counterweight as their skill level increases. Generally, one starts heavy and moves to lighter weights as control and ability improves. This means several different weights over time. But what if you could tune your counterweight to your exacting sweet spot as that sweet spot changes over time? Or what if you could simply adjust the weight to you, rather than you adjusting to the weight? Well, we have the answer!
