Key Features of DAIWA 2021 ALPHAS SV TW
HYPERDRIVE DESIGN
In 2021, DAIWA’s new baitcasting reels underwent a significant evolution, marking a new era of innovation. The term that embodies this transformation is "HYPERDRIVE DESIGN." This new design philosophy aims to elevate all basic performance levels, ensuring they remain consistently high over time. At its core is the HYPERDRIVE DIGIGEAR, which includes both the drive and pinion gears. Supporting this are three additional key components: HYPER DOUBLE SUPPORT (pinion gear support system), HYPER ARMED HOUSING (reel body), and HYPER TOUGH CLUTCH. These four critical elements, refined with DAIWA's cutting-edge technology and new innovations, collectively deliver exceptional drive performance. A model featuring HYPERDRIVE DIGIGEAR and enhanced rotational performance falls under the HYPERDRIVE DESIGN category.
HYPERDRIVE DIGIGEAR
HYPERDRIVE DIGIGEAR is a newly designed gear system for baitcasting and conventional reels, engineered to maintain strong and smooth rotation over time. DAIWA’s unique technology avoids reducing the module size of the gear teeth, which is crucial for durability. Instead, it enhances meshing efficiency by shaping the gear teeth with a bullet-shaped silhouette that optimizes the pressure angle. This design ensures the initial smoothness of the reel lasts longer, achieving an exceptional balance between smooth rotation and rotational durability. Compared to previous DAIWA gears, the noise felt during handle rotation, such as roughness, has been significantly reduced by over 50% in the HYPERDRIVE DIGIGEAR.
HYPER DOUBLE SUPPORT
The HYPER DOUBLE SUPPORT system is a pinion gear support mechanism that enhances smoothness, power, and lightness in the reel’s operation. By precisely supporting both ends of the pinion gear with two ball bearings, it ensures that the power input from the handle is transmitted without loss, allowing for powerful and light winding even under load. The pinion gear, a crucial component on par with the drive gear in baitcasting reels, has also undergone significant evolution. Like the drive gear, the pinion gear’s tooth surface has been updated with new specifications, and the use of special materials has greatly reduced issues such as corrosion, seizing, and damage, thereby significantly contributing to the gear's durability.
HYPER ARMED HOUSING (Aluminum)
The HYPER ARMED HOUSING is a body system designed to provide high rigidity and precision, supporting the internal structure of the reel to deliver smooth winding and power. A key requirement is the use of metal materials for the frame, which, when combined with side plates and set plates, ensures that the reel's fundamental performance is maintained over an extended period.
HYPER TOUGH CLUTCH
The HYPER TOUGH CLUTCH system delivers precise on/off performance, maintaining its reliability through thousands of cycles. It is designed to be highly durable, even in saltwater environments with high salt concentrations. Featuring an advanced insulation structure, this system has achieved a 99% reduction in sticking-related repairs compared to DAIWA's previous clutch systems, showcasing its exceptional performance in harsh conditions.
ULTIMATE CASTING LINE GUIDE(T-Wing System)
Traditional level wind systems were designed, as their name suggests, to lay the line evenly across the spool. However, during casting, they often created resistance, leading manufacturers to experiment with different internal diameters and shapes to enhance line release. But these efforts had their limits. Excessive enlargement of the level wind compromised its original function, restricting advancements to minimal adjustments, such as refining the internal diameter. Some solutions included increasing the distance between the spool and the level wind or narrowing the spool width to prevent the line from hitting the level wind at sharp angles. While partially effective, these methods were essentially temporary fixes that led to side effects such as elongating the reel body, reducing palming comfort, or decreasing line capacity.
DAIWA's TWS (T-Wing System) addresses these contradictions not with compromise but with innovation, achieving both precise line winding and an expanded resistance-free range during line release. By significantly widening the resistance-free zone where the line makes contact with the level wind, particularly right after it leaves the spool, TWS has dramatically enhanced the long-casting performance of DAIWA baitcasting reels. Simultaneously, the smooth line flow facilitated by TWS has proven effective in preventing backlashes.
SV (Super Versatile) concept
The SV concept maximizes the effectiveness of magnetic brakes to deliver practical advantages in a field. It significantly reduces the risk of backlash, making casting easier and more effortless. With minimal adjustment of the magnetic dial, the SV concept allows for a wide range of lure weights—from lightweight rigs around 4 to 5 grams to heavier lures—to be handled smoothly and without stress.
AIR BRAKE SYSTEM
The AIR BRAKE SYSTEM significantly enhances casting accuracy while minimizing the risk of backlash, providing a stress-free experience. During full casts, the brake engages effectively, but in low-speed operations like pitching, the inductor rotor remains retracted, reducing the braking force. This system allows for low-trajectory casting and seamlessly balances pitching and casting at a high level.
UTD (Ultimate Tournament Drag)
By re-evaluating the washers and grease from the ground up, DAIWA has refined the drag system to reduce initial resistance when a fish is hooked, ensuring the line starts to slip smoothly and consistently. This advanced drag system, which surpasses the previously established standards set by DAIWA, is designated as "UTD" (Ultimate Tournament Drag).
