Product Concept & Specifications
Nexx (Portugal)Engineering & Technical Analysis
Die Nexx X.404 nutzt ein EPS-Linersystem mit Mehrdichte, das entwickelt wurde, um hohe Aufprallenergie zu absorbieren und gleichzeitig die strukturelle Steifigkeit des Kinnbügels zu gewährleisten. Die aerodynamische Schale verfügt über windkanaloptimierte Konturen, die die Luftströmungsablösung steuern und so das Wummern bei hohen Geschwindigkeiten deutlich reduzieren – trotz der Halbschalen-Konstruktion.
Fit & Shell Structure
Intermediate Oval Shape
Balanced oval fit: standard ergonomic curvature fitting 80%+ of riders.
