X Rigid Rotor By using an aluminum alloy and verifying the thickness arrangement in detail through repeated 3D analysis, it realizes tougher rigidity, durability, and excellent rotation balance than ever before. This high rigidity also contributes to improved functionality of the drag and other parts.X Rigid Handle Highly rigid cold-forged handle specially designed for STELLA SW that transmits angler’s power without loss.High rigidity arm cam Equipped with a metal arm cam, just like the rotor, to increase rigidity. Transmits the power of STELLA SW without distortion, such as when winding line with a high load and during drag running. Smooth surface is maintained for a long period of time by metal plating treatment. This reduces damage to the line.Line roller for STELLA SW Special surface treatment (diamond-like carbon) reduces friction and prevents line wastage. In addition, a contact-type waterproof seal is installed to block seawater from entering the line roller section. The internal bearing is protected from the harsh environment, and durability is improved more than 10 times compared to the non-equipped model. *Based on our comparison test.Line roller looseness prevention mechanism The line roller section, which is the first to catch the pull of a large fish and is applied with force, is equipped with a mechanism to prevent loosening. The bolt that holds the line roller is doubly secured with a set screw to further prevent loosening.CI4+ handle knob (except 14000) Adopts a handle knob made of carbon material CI4+, which combines high rigidity and light weight. (14000 model adopts a lightweight hollow oval round knob)
