Produced by Italian sprocket specialist CHT Chiaravalli, these ergal rear sprockets have been made to obtain maximum lightness.
Why CHT ergal sprockets are highly performing
• Made of ergal 7075: high-strength aluminium alloy, mainly used in the aeronautical field.
• They are 70% lighter than conventional steel chainrings.
• Self-cleaning: the grooves at the base of the toothing, on both sides, facilitate the elimination of mud, extending the lifespan of the drivetrain (no minicross).
