The Campagnolo Centaur 10 Speed Cassette features a completely redesigned profile of the teeth, in line with the Ultra-Drive project, making it possible to achieve the maximum response speed at the moment of shifting. The synchronisation obtained by establishing a specific position of the teeth between sprocket and sprocket makes the passage from one sprocket to the next very fluid and fast. In order to not lose rigidity the last two are fitted on an aluminium frame.
