Characteristics

  • This bottom bracket uses Chronium Steel Bearings (ABEC5 /P5 – 2RS).

  • Fully sealed. Axial seals on bearings and fully sealed on all surfaces to avoid dust and water.
  • Asymmetric. This bottom bracket is asymmetrical because it takes up the space previously occupied by the spacer, making it more robust.
