Our new STRIKE features once more a super intuitive pumping with a certain flexibility that makes it easy to start planing without having to expend a lot of energy or learn a special technique. This STRIKE responds to pumping with immediate power.

We’ve worked on the wing’s balance and aerodynamics to ensure exceptional and superior performance, while maintaining control and precision. This new STRIKE offers an unrivalled smoothness of traction that makes it possible to ride effortlessly, as if using a smaller, very light wing.

The STRIKE’s control throughout the wind range is impressive, allowing you to easily handle gusts. For those who love speed, the wing provides a new “Going Forward” feeling that unlocks thanks to an impressive forward traction delivering fantastic horizontal acceleration.

In the low end, it never seems to suffer from air holes or heading winds, maintaining a constant glide and exceptional upwind abilities.

Thanks to its stiffness, accelerations, and massive pop and hangtime, the STRIKE will also have you hooked on freestyle. For your rotations, the wing turns easily on its own, allowing you to land all your tricks and try out new ones.

This STRIKE is much more than a new model; it’s a perfect blend of performance, a lightweight feel and smooth traction.

Design

The design of the STRIKE has been entirely revised. The central strut is now completely straight, which allows us to better control its deformation and possible twisting, while reducing drag. As a result, the infill is a bit lower and deforms less, and we’ve extended it almost all the way to the back. Our innovative Load Diffuser is reduced for weight gain, especially during freefly.

We’ve also added dihedral angle to improve stability and keep the wingtips out of the water when pumping and riding. The new leading and trailing edge tensions as well as a refined radial cut help keep the profile smooth and stable for incredible performance and control.

The accurate panel layout, precise load management and staggered seams continue to bring exceptional control of the profile, especially in the high end. The use of HITEX on the inflatable structure and TECHNOFORCE™ 52g and 66g on the canopy offer great resistance to elongation, and therefore greater durability and performances. The materials are also perfectly distributed to account for the different tensions, high pressures, and weight distribution in each specific area.

Small radial cuts are implemented on the wingtips and on the back of the strut to spread tensions. Aligning the fibre exactly along the load paths means that stretch can be controlled to a never-before-seen level on a wing. Located on the back of the strut, our Load Diffuser made of overlapping panels of hard Mylar and Dacron further helps maintaining the profile sleek and efficient, leading to the ultimate stability, performances, and longevity.

Thanks to this Sail Engineering and design work, the new STRIKE is an ideal compromise of performance, control, and smoothness. The wing feels stiff enough for any rider to perform and stay in control, but remains at the same time very progressive, offering a gentle and swift forward traction.

Handles

The new STRIKE is fitted with our new interchangeable handle system. Soft, hybrid or rigid handles, you now get to customize handles at your preference.

HITEX

To meet the specific needs of the development of wings and kites, and to offer a high-performance and durable product without using inaccessible materials, F-ONE has developed HITEX, a new high tenacity polyester. Available in 158g, and exclusively for F-ONE in 178g, this new material is incredibly resistant to elongation and increases the durability of wings and kites. HITEX is an innovative, high tenacity polyester fiber with an enhanced high-quality weaving and coating that increases the fabrics’ resistance. The 178g is a new weight and perfectly matches the needs of the center strut and center of its leading edge. The lighter 158g is used in the leading edge tips. Used throughout the inflatable structure of the wings and kites and designed to handle the high pressures when inflating, HITEX offers performance and resistance. Thanks to extensive Sail Engineering work, the R&D team has placed each weight of HITEX in different areas allowing absolute control of the shape session after session.

SAIL ENGINEERING

Sail engineering is the science of controlling our design and its behaviour while flying. These features have been created with one goal in mind: Mastering the kite's loads to maintain the desired shape for the longest time.

1 – WARP TENSION LINE

Woven fabrics feature a longitudinal 0° yarn (Warp) and a transversal 90° yarn (Weft). Therefore, a fabric has great elongation resistance and strength capacities if you apply tension at 0° or 90° along the yarns. But it will deform and stretch when tension is applied at, let’s say, 45°.

2 – LOAD CONTROL PANELING

When engineering the load control paneling, we make sure that fabrics panels are warp/weft oriented, meaning that the load path runs through the yarns. Fabric and seams are then in the best position to receive tensions and maintain the original kite shape.

3 – STAGGERED SEAMS

Most of the kite’s back lines tension is distributed through the trailing-edge panels and seams. As seams are significantly stiffer than the fabric they join, they tend to strain under loads and therefore deform the profile. The staggered seams break that line of tension by balancing the stiffness between seams and cloth, which helps distribute the load over a wider area and maintain the original shape even under high loads.

4 – FABRIC WEIGHT MANAGEMENT

Our sails feature four different cloth weights, from 52 up to 155gr/m². Sail engineering allows us to control our shape and drive load tensions without using heavy fabrics or bulky designs, therefore we can reduce fabric’s weight and use. It results in a lighter, optimized kite.

TECHNOFORCE

TEIJIN’s TECHNOFORCE™ is the most reliable high density polyester fabric. Its tear-stopping structure using thin and high tension yarn makes the fabric ultra-durable.

It has a great proven track record of lightness and durability.

REACTOR VALVE

The reactor inflation valve offers a high flow connection that twist locks the pump hose to the kite for an easy and super-fast inflation and deflation at the push of a button.

It provides a high air flow rate between the struts and leading edge.

PRE LOADED CANOPY

From the beginning, our wings have had a unique canopy tension that can be compared to that of a harden up windsurfing rig. Our wings are therefore “pre-tensioned” and made to adapt. This ideal tension of the trailing edge when riding guarantees much better performances upwind and in light winds.

LOAD DIFFUSER STRIKE

Located on the back of the strut, our innovative Load Diffuser made of overlapping panels of hard Mylar and Dacron further helps maintaining the profile sleek and efficient, leading to the ultimate stability, performances, and longevity.

RADITAL TIPS

Small radial cuts are also implemented on the wingtips and on the back of the strut to spread tensions. Aligning the fibre exactly along the load paths means that stretch can be controlled to a never-before-seen level on a wing.

STRIKE VALVES

The wing features two highly efficient inflation valves: one on the central strut and one on the leading edge. These two areas of the wing face different forces, and thus require two different pressure recommendations. As a result, the central strut is thinner in diameter and gains in rigidity thanks to its independent valve that allows for a better control of its pressure.

STRIKE KEVLAR REINFORCEMENTS

The wingtips are protected with abrasion-resistant Kevlar® fabric reinforcements.

INTERCHANGEABLE WING HANDLES SYSTEM

In 2024, all our wings are fitted with our new interchangeable handle system. Whether you’re looking for a light and comfortable setup with soft handles, a more direct and aggressive ride with hard handles or something in between with our innovative hybrid handles, we’ve got you covered. Wings come with soft handles pre-installed, but swapping a handle set between wings is quick and easy thanks to our screwless setup.
