The Supertype cassette is a component that has been studied and designed for maximum lightness, customization and functionality. The sprockets are made of AL 7075-T6, and finished in CNC to ensure perfect indexing and guarantee compatibility with all transmission systems. The surface treatment of anodizing with the HT (Hard Treatment) process gives the sprockets their particular charcoal colouring and increases their resistance to wear. The cassette's special construction, with separated sprockets, allows for custom gear teeth combinations, with respect to transmission capability.* 11 Speed Campagnolo compatible* AL 7075-T6 CNC Sprockets* Hard Treatment anodization* First position sprocket in stainless steel. * AL 7075-T6 lock ring* Weight: 150g (12-25)**Gear Increments*** MCX102: 11/12/13/14/15/17/19/21/23/25/27* MCX103: 12/13/14/15/16/17/19/21/23/26/29* MCX104: 16/17/18/19/20/21/22/23/25/27/29* MCX105: 12/13/14/15/17/19/21/23/25/27/30
