## Overview
- **Product**: 6D ATS-1R Flow Rot
- **Brand**: N/A
- **Category**: Helmet
- **Summary**: Carbon-Rennmotorradhelm mit ODS-Technologie für multidirektionale Aufprallabsorption. Der 6D ATS-1R Flow Rot ist von 6D als hochintegres Helm-Schutzsystem konstruiert und nutzt eine Strukturschale aus Kohlefaser-Verbundschale (Carbon). Dieser Schichtaufbau ermöglicht eine progressive Dissipation kinetischer Aufprallenergie bei Stoßverzögerungen, verteilt lokale Belastungsspitzen gleichmäßig über die äußeren Lamellenschichten und minimiert die Verformungsübertragung in den mehrteiligen EPS-Dämpfungskern. Zertifiziert nach ECE 22.06 ... Weiterlesen
