Sprockets with an Ultra Drive™ design enable optimised downshifting under loads. First-class shifting performance is achieved thanks to maximum synchronisation between the sprockets and micrometric machining of the teeth. The nickel-chrome surface treatment makes the sprockets extremely resilient and extends the service life of the chain.
