Engineering & Technical Analysis

Das HJC RPHA 11 Pro bietet fortschrittliche Sicherheit mit seinem PIM+-Schädel, der eine leichte Dauerhaftigkeit und eine hohe Stoßfestigkeit bietet. Seine mittlere ovale Kopfform gewährleistet einen sicheren, bequemen Sitz, während fortschrittliche Lüftungskanäle einen Luftstrom fördern, der Fahrradfahrer kühl hält. Die Helmform "Track/Race" priorisiert Aerodynamik und Leistung, was es zu einem idealen Helm für Hochgeschwindigkeitsfahrten macht.
