The Shimano Stradic CI4 Reel is made of a carbon fiber thats over 1-1/2 times stronger than normal XT-7 graphite and is over 20% lighter. Because it doesnt contain metal, its impervious to rust. CI4 stands for ‘Carbon Interfusion’ with the 4 referring to the number of electrons in the Carbon atom. The Stradic CI4F makes use of a new carbon fiber material on both the frame and sideplate and the internals feature all the latest Shimano designs including Paladin gear durability enhancement. The reel also makes use to the complete spectrum of features within the company’s propulsion line management system as well as the Aerowrap II Oscillation. The Stradic now features a waterproof drag and there are a number of features designed to make maintenance both quicker and easier including the maintenance port and a repairable clicker.

So, as a result of its strength and weight, we can create an extremely lightweight reel with very precise tolerances. CI4was originally developed for the brake calipers on Shimano’s top end “Dura-Ace” road groupo as well as the front chainring of their XTR premium mountain bike groupo. These were the very components chosen for use by Lance Armstrong during his seven year dominance over Le Tour de France!
As far as I can tell they are trying to compete with Daiwa’s own “Zaion” body, by producing there own new body material named C-14. C-14 is a new carbon material that Shimano claims to have the strength of metal bodied reels while retaining the lightness of carbon. Flex is also eliminated in the C-14 body, which is a common downfall in carbon/graphite reels.
