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 Steel Bearings (ABEC5 /P5 – 2RS).
  • The cups of our bottom brackets are made from 7075 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.
