San Clemente, CA – KINETIXX Golf today announced the launch of SyrgeX and FlexurX, two next-generation wood shaft platforms built around Kevlar® EXO™, the most significant advancement in aramid fiber technology in more than 50 years. KINETIXX is the only golf shaft manufacturer with exclusive access to Kevlar® EXO™, pairing this breakthrough material with its utility-patented hybrid construction to deliver unprecedented strength, consistency, energy transfer, and feel. Beyond exclusive access, KINETIXX uniquely owns and controls the design, production, and commercialization of the proprietary unidirectional prepreg architectures used in these shafts, manufacturing the material itself rather than sourcing it externally. This vertically integrated capability allows KINETIXX to engineer performance at the material, fiber, and structural levels simultaneously, a feat no other golf shaft manufacturer can replicate.
“This launch represents far more than two new shafts,” said Jason Horodezky, CEO of KINETIXX. “We own the material science, the prepreg architecture, and the manufacturing process end to end. Because we actually produce the commercially viable unidirectional prepreg in-house, we can build performance into the shaft at a molecular level. There is no shortcut to that capability — and no other company in golf can make shafts like these.”
Kevlar® EXO™ is a copolymer aramid fiber engineered for extreme performance. It has been in development for 15 years and has expanded to other key applications such as crash-resistant fuel bladders for Formula One; protecting satellites, deployable structures, and spacecraft in space from orbital debris; and now looks to the sports world with best-in-class golf shafts. KINETIXX’s proprietary prepreg forms of Kevlar® EXO™ are not single-purpose solutions, but a scalable materials platform that will be deployed across future applications both within and beyond sporting goods, including advanced industrial systems and next-generation medical devices requiring controlled flexibility, fatigue resistance, and long-term structural reliability. Compared to standard Kevlar®, it is approximately 30% stronger, 30% lighter, and 30% more flexible. That added ductility allows the material to absorb impact energy rather than fracture, which is essential in high-speed golf applications where carbon fiber alone can be brittle. By combining Kevlar® EXO™ (tension and impact absorption) with high-modulus carbon fiber (compression and stiffness), KINETIXX achieves a composite system that stores, controls, and releases energy more efficiently than any existing conventional shaft design. Because KINETIXX engineers and manufactures the prepreg material itself, these composite systems cannot be reverse-engineered or duplicated using conventional table-rolled or third-party-supplied materials.
“We couldn’t be more excited to partner with KINETIXX on a project that brings together two innovation‑driven brands,” said Scott Janco, Kevlar® EXO™ Application Development. “By combining KINETIXX’s cutting‑edge approach to golf performance with the breakthrough power of Kevlar® EXO™, we’re setting the stage for technology that can truly change the game.”
SyrgeX: Filament-Wound Precision, Vacuum-Cured Consistency
SyrgeX represents the most advanced execution of KINETIXX’s utility-patented hybrid construction. A 30T (0°) and 40T (45°) high-modulus carbon fiber core is paired with a homogeneous, circumferential filament-wound Kevlar® EXO™ exoskeleton, all vacuum-cured into a low-void, ultra-dense composite. The Kevlar® EXO™ filament and prepreg materials used in SyrgeX are produced exclusively by KINETIXX, enabling fiber placement, tension control, and material consistency unavailable to manufacturers relying on outsourced composite supply chains.
This architecture solves the long-standing trade-off between bending stiffness and torsional stability. The 0° fibers deliver elite linear strength and a stable kick profile, while the 45° fibers and Kevlar® EXO™ hoop layer dramatically resist twisting and ovaling under load. The result is a shaft that stays round, stays square, and recovers faster, even on high-speed or off-center strikes.
Key performance outcomes include:
- Pure kinetic energy transfer from reduced resin content and higher fiber volume.
- Spineless, concentric construction for ultra-tight dispersion.
- Reduced vibration and enhanced feel, as the Kevlar® EXO™ exoskeleton filters harsh, high-frequency impact shock.
- Exceptional durability and impact resistance without added weight.
SyrgeX is available for both drivers and fairway woods. This line is engineered for mid-to-high swing-speed players seeking bulletproof distance with bulletproof precision, delivering a high, stable kick point, low torque, and lower-mid launch/spin characteristics.
FlexurX: The Most Advanced Table-Rolled Shaft Ever Developed
FlexurX applies Kevlar® EXO™ innovation to a vacuum-cured, table-rolled platform, creating a shaft that redefines what is possible in traditional flag-wrapped construction. A 30T/40T high-modulus carbon fiber core is reinforced with a proprietary ultra-thin Kevlar® EXO™ unidirectional outer ply at 45°, precisely oriented for stability, loading, and recovery. This unidirectional Kevlar® EXO™ prepreg is wholly engineered and manufactured by KINETIXX, allowing exact control over fiber orientation, resin content, and ply thickness at a level not achievable through third-party materials.
This Kevlar® EXO™ exoskeleton acts as a structural safeguard, preventing deformation and ovaling during aggressive swings while adding elongation and vibration dampening that carbon fiber alone cannot provide. Vacuum curing eliminates irregularities like resin pockets, ensuring every FlexurX shaft is lighter, more consistent, and performs exactly as designed.
Performance benefits include:
- Higher ball speed through efficient energy transfer.
- Tighter dispersion and greater forgiveness on off-center hits.
- Smooth, solid feel with filtered vibration despite high stiffness.
- Broad playability across a wide range of clubhead speeds.
FlexurX is available for both drivers and fairway woods. This line is engineered for golfers who demand maximum stability, forgiveness, and efficiency without sacrificing feel — particularly players with moderate to fast swing speeds who want confidence on aggressive swings and protection on imperfect strikes. Designed for those who value tight dispersion, consistent ball speed, and smooth feedback, FlexurX is ideal for competitive amateurs, serious club golfers, and fit-focused players seeking reliability, playability, and tour-level consistency.
“Because we design and produce the prepreg material ourselves, FlexurX isn’t constrained by traditional manufacturing limits,” said Horodezky. “We can tune elongation, stability, and feel with a level of precision that simply doesn’t exist elsewhere in the market. These shafts aren’t iterations of what’s come before; they’re the result of a materials platform that will ultimately extend well beyond golf.”
Both SyrgeX and FlexurX are built on KINETIXX’s philosophy of material-first engineering: aligning fibers along calculated load paths, optimizing fiber angles and wall thickness by flex, and vacuum curing to achieve unmatched structural integrity. Unlike centerless-ground shafts, KINETIXX shafts are produced as true net parts, preserving concentricity and consistency from raw material to finished product.
With exclusive access to Kevlar® EXO™ and a proprietary hybrid construction process, KINETIXX has created not just new shafts, but a new performance category — one that combines strength, flexibility, durability, and feel in ways previously thought incompatible. These are shafts that cannot be copied, licensed, or reverse-engineered because no one else controls the material itself.
SyrgeX and FlexurX are now setting the standard for what a modern golf shaft can be: stronger, smarter, and engineered to protect and elevate every swing.
