On a classic Parawing with fixed geometry, power reduction often comes with an overall change in wing behavior. Result: in gusts, the rider must deal with narrower control margins, less stable heading management, and a useful wind range that tightens quickly.
This is precisely the mechanical lock that SROKA sought to break with the PushBar System®. The FYNIX is the first Parawing equipped with true dynamic depower/power-up thanks to the PushBar System®: the lines slide inside the 32 cm carbon bar and modify the wing geometry in real time. The term PushBar System® is a registered trademark of SROKA, and the associated innovation is the subject of a patent application filed with INPI, currently patent pending.
Applied to the FYNIX SROKA, this principle opens a new way of reading the Parawing: more stability, finer piloting, better harness exploitation, and the ability to maintain more control when wind increases.
1. The real problem with fixed-geometry Parawings
On a fixed-geometry wing, the rider cannot freely choose between power, comfort, and heading: everything is linked. As soon as traction needs to be reduced, there is often a drop in overall efficiency, a more unstable feeling in gusts, and less serene exploitation of the chosen size.
In other words, much of the limit comes not only from wind or rider level, but from how power is managed on the wing. This becomes decisive when trying to launch early, stay efficient upwind, or hold longer in strong wind. The subject is covered in depth in our analysis of a Parawing's wind range.
2. What the PushBar System® changes
The PushBar System® was designed to provide dynamic power modulation without reproducing the limits of a classic bar on fixed geometry. The lines slide inside the 32 cm carbon bar: by pushing the bar, the rider creates a central fold that reduces the wing surface without changing the leading edge angle of attack. The goal is simple: allow the rider to stay more powered when it makes sense for early takeoff, then regain control once launched.
In this logic, the system helps to:
- better absorb gusts
- improve overall wing stability
- better maintain heading and useful speed
- more serenely exploit certain sizes with harness
- rationalize the quiver by increasing the exploitable wind range per size

Reference test configuration
- Rider: 80 kg
- Foil: UHA 1100 cm²
- Board: LW Middle Length 90 L
- Sizes tested: 3 m², 4 m², 5 m²
Ranges observed in this configuration
- 3 m²: 23 to 35+ knots
- 4 m²: 14 to 29 knots
- 5 m²: 10 to 25 knots
These ranges assume adapting foil and board size (the top of each range is a gust margin handled thanks to the PushBar System®, not comfortable established wind). In this test framework, using the 4 m² with harness allowed an 80 kg rider to handle gusts beyond 25 knots without changing size: these are still occasional gusts, not continuous navigation at this level.
3. Performance reading: heading, control, and comfort
On the water, the difference is not just about having less traction. The benefit is mainly measured in navigation quality: ability to keep a larger wing when needed, superior comfort in wind variations, and maintaining a cleaner trajectory.
The mechanics are simple to understand. On a fixed-geometry wing, an overpowered rider cannot cut power in the gust: they suffer it, the sail moves back in the wind window, drag increases, and heading degrades. With the PushBar System®, power is cut without the angle of attack changing: the gust passes and heading is maintained.
In this logic, tests notably highlighted:
- a gain of approximately 2 to 4° upwind compared to fixed-geometry wings, in the test protocol described above
- more active power management in gusts
- reduced fatigue sensation on long sessions
- better consistency between early launch and control once underway
| Criterion | Fixed-geometry Parawing | FYNIX SROKA with PushBar System® |
|---|---|---|
| Power management | More constrained traction reduction, with quick compromises | More dynamic modulation and pursuit of finer control |
| Reaction in gusts | More sensitive to sudden variations | Behavior designed to remain more manageable in gusts |
| Upwind performance | Heading penalized faster as control degrades | Observed gain of approximately 2 to 4° in test configuration |
| Harness use | Limited sooner depending on size and wind | Better possible exploitation of certain sizes |
| Fatigue | Sessions sometimes more physical | More serene and less suffered navigation |
| Useful range per size | More restricted | Wider in the usage framework presented |
| Quiver rationalization | More sizes needed to cover a wide spectrum | Potentially lighter quiver thanks to better versatility per size |

4. See the PushBar System® in action
Key takeaway: the PushBar System® is not presented here as an absolute or universal promise. It is a SROKA development intended to improve active power management on the Parawing. PushBar System® is a registered trademark of SROKA, and the associated innovation is currently patent pending.
FAQ: PushBar System® and wind range
What does true depower/power-up bring to a Parawing?
True depower/power-up allows dynamic power modulation without suffering the same limits as fixed geometry. This improves control, stability in gusts, and exploitation of the useful wind range.
What's the difference from simple depower?
Simple depower reduces traction but doesn't necessarily change the deep aerodynamic logic of the wing. The PushBar System® aims to bring finer control of power and wing behavior in use.
What does the controlled profile break at the center allow?
It allows progressive and controlled power reduction without instantly losing all useful wing behavior. This helps better absorb gusts and maintain more control.
What heading gain was observed?
During tests, a gain of approximately 2 to 4 degrees upwind was observed compared to fixed-geometry wings, in the protocol described above. The reason is mechanical: an overpowered rider who cannot cut power suffers the gust, the sail moves back in the window, and heading degrades.
Under what conditions were the tests conducted?
Reference tests were conducted with an 80 kg rider, a UHA 1100 cm² foil, an LW Middle Length 90 L board, and sizes of 3 m², 4 m², and 5 m².
Is the PushBar System® compatible with a harness?
Yes, harness use is part of the usage scenarios mentioned for the FYNIX, particularly to better exploit certain sizes in sustained wind. See our Parawing harness guide.
How does the system react in gusts?
The principle sought is to bring more active power modulation and better control of wing behavior in wind variations.
Does the PushBar System® help with takeoff or relaunching?
The system primarily aims to improve power management and control in navigation. Relaunching help always depends on conditions, rider technique, and overall configuration.
For which practices is the system relevant?
The PushBar System® is designed for uses such as Freeride, Downwind, technical progression, and certain performance-oriented practices.
Is the PushBar System® protected?
Yes. PushBar System® is a registered trademark of SROKA, and the associated innovation is the subject of a patent application filed with INPI, currently patent pending.
Does the system adapt to all levels?
The FYNIX equipped with the PushBar System® is presented as potentially suitable for initiation, progression, Freeride, and performance, depending on size, spot, and technical level.
Does the system eliminate all limits?
No. It provides an additional control margin but does not replace foil learning, choosing the right size, or reading wind and water conditions.
