BI-METALLIC X-RACE SPROCKETS
Produced by Italian sprocket specialist CHT Chiaravalli, these bimetallic X-Race rear sprockets have been crafted to achieve maximum performance without compromise.
Why CHT bimetallic X-Race rear sprockets are highly performing
• Lightness: the internal part in ergal 7075, a high-strength aluminium alloy mainly used in the aeronautical field, makes them 40% lighter than conventional steel rear sprockets.
• Maximum durability: the toothing made of high-strength ET-RG45 steel, makes them 3 times more durable than aluminium rear sprockets.
• Self-cleaning: the grooves at the base of the toothing, on both sides, facilitate the elimination of mud, extending the life of the transmission.
