The Coresolid Philosophy is characterized by two major functional elements. The first is adding stiffness and rigidity, and the second is creating a smooth continuous rotation feeling. The Coresolid philosophy evolves around the use of specific strong materials, and a configuration that is optimized for delivering smooth power when reeling. What separates Coresolid reels from other reels is in the construction of the reel's body and the gearing. Using high end body materials enhances the durability, strength, and overall performance of the reel. Coresolid reels have very stiff bodies that do not flex or bend, even under high pressure.
