Centaur™ sprockets use the Ultra·Drive™ system and are the fruit of continuous research and development to improve our products.
The Ultra·Drive system makes shifting more precise and fluid, especially thanks to the careful machining and treatments that the sprocket teeth have undergone. The special sprockets pattern interfaces perfectly with the rest of the drivetrain components, especially the chain and chainrings, thus bringing performance to levels of outstanding excellence. The sprockets are made with the same type of steel as Record™ and Chorus™ sprockets. The only difference is that they use a different system of supports and spacers.
