Rod Evolution

Driven by our relentless commitment to provide every angler the upper hand, our rod design process starts with understanding the angling equation we are trying to solve, which translates to a rod’s desired flex, feel, and functionality. We obsess over the minutia of rod action with a conviction to designing the most efficient casting and fishing tapers possible.

While refined flex patterns are the soul of our rods, technology is the engine that provides performance. Our desire to improve the angler experience pushes us to develop next-level blank materials, design lay-ups, and components. These advancements, working in union with carefully conceived actions, ultimately deliver peak performance, effectiveness, and durability.

Finally, thirty-two sets of skilled hands craft every St. Croix rod in the most advanced manufacturing facilities in the fishing world. We fixate on constant process improvement with an ever-present eye on efficiency, sustainability, and company culture. After all, an ethos is only as strong as the people who preach it.


Rod action describes how and where the rod flexes, ultimately defining the performance attributes and capabilities of the rod. For example, a rod designed for a wide range of fishing applications and conditions needs adequate lifting capacity, high line speed, and dependable loop stability. If it is a freshwater rod, it must also mend well at distance. A fast-action rod features a stiff butt and mid-section with a softer tip and is ideal for these tasks. The location where the tip begins to soften affects power and accuracy. A freshwater fast action typically softens slightly lower on the blank compared to a fast/salt action, helping the angler generate tight loops off the tip of the rod, ideal for making precision casts. In contrast, a fast/salt action softens closer to the tip, which creates additional power necessary for both casting and fishing in saltwater environments.

Alternatively, a rod built specifically for technical dry fly fishing must lay down delicate casts, protect gossamer tippets, and possess the ability to hold a big fish on a small fly. For these reasons, a medium-fast or moderate action with a softer butt and mid-section are ideal choices.

An angler’s preferred casting stroke is a final consideration. Casters with a short, aggressive stroke will get maximum performance from a faster action. Conversely, casters with a long, smooth stroke will appreciate the reserve power of a medium-fast or moderate action. The most proficient anglers understand how to modify their casting stroke, allowing them to utilize the best tool in any given situation.



Our R&D engineers have decades of experience designing fly rods with our vast family of carbon fiber materials. In fact, we collaborate closely with our vendors to create proprietary materials designed and manufactured to our exact specifications. That level of control coupled with 75 years of rod-building knowledge allows us to create dynamic fishing tools that utilize a complex blend of carbon fiber in each rod, which allows us to precision craft the perfect flex, feel, and functionality for the tool’s intended purpose. /p>


Our relentless passion for improving the angler’s experience drives a continuous search for new technologies and manufacturing processes that will improve fly rod performance. Every new advancement – from new prepreg carbon to advanced resin systems – is put through scrupulous tests in our state-of-the-art engineering lab and in the field before it makes the roster.

MITO® Graphene unlocks the power of hybrid polymer materials with specialty additives which dramatically improves overall rod performance. Functionalized graphene enhances blank strength by 20%, which improves the strength-to-weight ratio and reduces swing weight. Additionally, it optimizes tip recovery, helping the caster generate staple loops and high line speeds. Finally, functionalized graphene boosts torsional rigidity, which greatly improves accuracy, giving the angler ultimate control.
