Nautilus began with its CCF drag system—a sealed brake combining cork and carbon fiber discs that set a new standard for smoothness and minimal startup inertia. The NV‑CCF followed, offering improved strength, lighter weight, hybrid ceramic bearings, and a titanium drag shaft while maintaining the signature performance of the original design. The award‑winning CCF‑X2 doubled drag strength and smoothness, halved startup inertia, and featured dual-action cork/carbon braking, hybrid ceramic bearings, ActivSeal protection, and a broad adjustment range via the InfinAdjust knob. Their X‑Series uses the XCT drag system, a compact sealed Teflon and carbon fiber disc drag that preserves smooth, lightweight performance in minimalist reels. Finally, the GTX employs the Pentadrag system—a massive five‑surface brake combining carbon fiber discs with cork/Kevlar/carbon hybrid layers.
