Usinée avec une grande précision dans un aluminium 7075 T6 très léger et très résistant.
Profil dessiné pour les dents qui permet de faciliter l’évacuation de la boue et réduit au maximum les pertes de puissance dûes à la friction entre la chaîne et la couronne.
L’anodisation durcit la matière en surface et améliore aussi l’esthétique. Des alésages sont réalisés sur la couronne à des endroits stratégiques afin d’alléger la pièce sans diminuer la résistance.
Cette couronne vous apportera un gain en poids, en puissance, en résistance et en longévité. Un atout pour le MX, SX ou l’enduro.
