With this tube in tube tool, we can easily insert a smaller tube inside another tube. The purpose is to gain stronger force/retraction at fork end (or center of gravity for the whole band set closer to fork side). This enable much faster speed and more powerful for shooting!
Watch below video to know how to use it. Our set includes an additional guiding rod to lead the bigger tubes on the main pipe by inserting one shorter end into the main pipe.
