Cassette Campagnolo Chorus 12-speed 11-34

The Chorus 12s 12-speed cassette from Campagnolo allows 1-tooth jumps up to the seventh position and still only takes up the space of the 11s sprocket set. Therefore, the 12s cassette is also perfectly compatible with the current Campagnolo 11s freehub bodies. The two larger groups of three consist of one piece, which avoids energy losses. The spacer rings are made of aluminium and all have the same thickness. These spacers have optimised the spacing of the sprockets so that the chain is perfectly aligned at all times. This ensures a long service life for the entire cassette. Also thanks to the special surface treatment of the sprockets, they are harder and therefore more durable with improved smooth running.
