PARK FALLS, WI – Physics is the science of matter – its motion and behavior through space and time and encompassing the related core entities of energy and force. It’s the foundation of varied scientific disciplines and mathematics. Physics has laws that cannot be broken, only better understood and then applied. Physics remains a vast frontier guiding human technological advancement.

PHYSYX is the new master of matter, motion, energy, and force on the water. Its unique materials and designs converge to manifest a better machine. PHYSYX is an evolved lever and conductor of energy. Anthropometric design ensures it’s also a better extension of the angler’s own body, combining near-bionic-level control, balance, precision, and tactile feedback with maximum comfort. PHYSYX exists to guide anglers to new levels of capability and accomplishment.

While the laws of physics bring order and continuously expanding levels of understanding to our Universe, the new laws of PHYSYX govern angler performance by increasing everything that’s possible on the water.

Presenting PHYSYX, an all-new series of 25 technique-focused freshwater rods from St. Croix, conceived in science to evolve and advance the angling experience.


What Makes PHYSYX Unique?

Molded Carbon Fiber TRIGON Handle – An evolution of the innovative and award-winning agglomerated cork TRIGON handle introduced last year on Mojo Bass, this rigid, molded carbon fiber version takes TRIGON’s benefits of dramatically increased comfort and control to all-new levels, while offering superior energy transmission.

Molded Carbon Fiber DYNAMIX Reel Seat – The next-generation St. Croix DYNAMIX reel seat is stronger, lighter, and transmits energy better than the previous DYNAMIX reel seat, while blending seamlessly with the TRIGON handle to create the ultimate angler interface.

SCIV+ Carbon Fiber Blanks – An exotic blend of SCIV and SCVI material creates blanks that are exceptionally refined, balanced, light, strong, sensitive, and optimized for their intended techniques and presentations. Select moderate-action reaction-bait models have iACT Glass blanks, which are a hybrid layup of SCIV+ and 100% linear S-glass materials. PHYSYX’s premium performance is enhanced by all top St. Croix technologies, including FRS, ARTTM, IPC®, and TET.

Titanium Guides – All PHYSYX models receive premium, rigid titanium guides with silicon carbide rings. These advanced guide trains support maximum performance with all line types and further promote PHYSYX’s supreme balance.

High-Tactile TPU Grip Lines – Angler grip is enhanced in all weather conditions via strategically placed TPU grip lines that are molded into (not surface applied) PHYSYX’s carbon fiber handle. TPU is a unique thermoplastic polyurethane material featuring elasticity, transparency, and resistance to oils, grease, and abrasion. These TPU grip lines have been rigorously tested with respect to sunscreens, bug sprays, and other common chemical substances anglers come in contact with to ensure durability.

Rear Trigger – A unique rear-trigger design near the base of the handle on PHYSYX casting and spinning models works in conjunction with the TRIGON handle design to further promote control and accuracy during casting. This innovative design feature benefits all anglers but excels when making precise presentations to fish on live sonar.

25 Models – PHYSYX is a complete, technique-optimized freshwater series consisting of 17 casting models and 8 spinning models to guide anglers toward new levels of accomplishment and success. PHYSYX’s 25 models include existing angler favorites like the C70HF and C70MHMF, as well as new lengths, powers, and actions like the C76HMF.

15-Year Warranty – Designed and handcrafted in Park Falls, Wisconsin, USA, PHYSYX is backed by a 15-year warranty and St. Croix service.
