It’s the Delta 2’s little brother! We are extremely excited about this wing, and think that it represents as much of a leap forward in performance designs as the Delta 2 has proven to be. The Rush 4 has class-crushing performance, and some features which we have never before applied to the Sport-Intermediate class, including Ozone SharkNose Technology.
Over the past three years, the SharkNose has proven to be one of the most important innovations in the sport of paragliding. The concept has now been thoroughly tested on our competition and performance XC class wings, and we feel that its arrival in the Sport-Intermediate class is an important milestone. The SharkNose profile provides vastly better behavior in performance and stability at both high and low angles of attack. In accelerated flight, the SharkNose profile is more stable, with better inflow to the cell openings and less drag at the leading edge. At slower speeds, and during intense brake inputs (for instance while coring tight thermals) the SharkNose profile is highly spin resistant, providing a longer and more progressive brake travel which the pilot can easily use to their advantage.

At Ozone, we are obsessed with “free” performance upgrades, which come as the result of improvements in materials technology and design factors which reduce drag without compromising passive safety or comfort. The Rush 4 has benefitted from a 25% reduction in line drag compared to its predecessor, thanks to a more advanced 3-Line design.
The Delta 2’s renowned balance of performance and comfort is the result of the new SharkNose, an advanced arc, and very low line drag. The Rush 4 features all of the same modern design advantages, and our testing has shown that this is a wing that will inspire confidence in active air. We have maintained a moderate aspect ratio, which is one of the keys to comfort. On launch, the Rush 4 rises in a balanced and predictable manner, and its compact and coordinated feel must be experienced to be believed.
In much the same way that the Delta 2 put huge smiles onto the faces of our R&D Team during the final testing phases, we think the Rush 4 will more than satisfy even the most demanding pilots in the Sport-Intermediate class, and maybe even tempt some pilots from other more advanced classes, as well. Overall, it has a very similar feel to the Delta 2 in terms of handling, precision, solidity, and spin-resistance while coring lift, and our early testing has shown that its performance is unique in the class.
