Characteristics

• • Dual Cup Technology.  Two aluminium cups that perfectly align bearings on both sides, creating a solid center joint that eliminates any noise or movements issues. Find out more about our technology here.
  • This bottom bracket uses Chronium Steel Bearings (ABEC5 /P5 - 2RS).
  • The cups of our bottom brackets are made from 6061 Aluminium, a high-strenght aerospace-grade aluminium on which we apply a T6 treatment. That makes the material harder and more durable, ensuring that our cups mantain top performance over time.
  • 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.
  • Lighter. The number of pins on this bottom bracket has been reduced to make it lighter.
