Sustain FK Spinning Reel

Near-Zero Inertia. Infinite Drive. Sustain FK Spinning Reel.

The Sustain FK is built around a single obsession: eliminating every source of resistance and inefficiency in a spinning reel. From the asymmetrical MGL rotor that starts spinning with almost no effort, to the InfinityDrive gearing that reduces internal friction by up to 40%, every system in this reel is engineered to give you more sensitivity, more power, and more control with less effort.

Technology That Changes How a Reel Feels

• Asymmetrical MGL Rotor — A rotor design with near-zero startup inertia that begins rotating the instant you turn the handle, with no lag or resistance. The result is a reel that feels alive in your hand and responds instantly to every input.
• InfinityDrive Gearing — A proprietary gear system that reduces internal friction dramatically, delivering more cranking power with less effort — critical when fighting large fish or working heavy lures for extended periods.
• InfinityXross Gearing — Cross-hatch gear tooth geometry that increases the contact surface between gears, improving smoothness and durability under load.
• InfinityLoop Line Lay — A precision oscillation system that lays line on the spool in a tight, consistent pattern, maximizing line capacity and improving casting distance.
• Anti-Twist Fin — Eliminates line twist at the point of entry into the spool, reducing tangles and maintaining line integrity over time.
• Rigid HAGANE Body & CoreProtect — A cold-forged aluminum body that eliminates flex under load, with CoreProtect water resistance to keep the internals protected in wet conditions.
• Duracross Carbon Drag System — Smooth, powerful drag with carbon fiber washers for consistent pressure across the full range.

Who It's For

Serious anglers who fish streams and technical freshwater environments and want a reel that performs at the absolute highest level — where every advantage matters.
