The perfect teeth design results in a perfect synchronization between shifting and chain movement. The six larger sprockets are divided in triplets, which are mounted on special frames to increase rigidity. Every sprocket tooth is designed and placed to perform a specific function, such as raising or lowering the chain of giving maximum power transmission to the wheel.
