Kewlus Cobra Bag Springs

Want to change the dynamics of your cobra bag? All Kewlus Springs, like all Kewlus parts are modular components, allowing you to quickly and easily swap from one to another. The spring is the engine of the Kewlus reflex training system. Changing the spring changes the way the reflex punching bag performs. Use the Striker Spring to achieve maximum speed, the Reacher Spring to get a greater range of movement or the Prime Spring to get the perfect balance between the two. The lower cost Classic Spring is a great way to get started, especially if you're considering the DIY option.
