Available on Trio spinning reels, Okuma's Crossover spool brings us the best of both worlds by employing aluminum where needed for strength and rigidity, and using composite where possible to reduce weight. "For the main body of the spool, we use a polymer material called Nylon66, which contains additional fiber for maximum durability," Bretza says. "Graphite spools tend to flex where the shaft goes through the center of the spool. Okuma wanted to ensure critical alignment of the shaft and drag washers, and avoid any potential for flexing, so we designed the Aluminum Drag Chamber. This aluminum cage holds the drag washers and screws into the top of the spool, so the washers are housed in a strong chamber and run on the same smooth surfaces found in an all-aluminum spool. The ADC also allows for precision alignment because the spool shaft runs through aluminum, not graphite."
