CI4 stands for Carbon Interfusion with the 4 referring to the number of electrons in the Carbon atom. Ultimately, this means CI4 is reinforced Carbon Fiber. The new CI4+ is the next generation of our CI4 material and 250% stronger.
It is over one and a half times stronger than our normal XT-7 graphite and is over 20% lighter. Because it does not contain metal, it is impervious to rust.
So, as a result of its strength and weight, we can create an extremely lightweight reel with very precise tolerances.
