Its core innovation lies in the DUB spindle, which unifies crankarm compatibility across various bottom bracket specifications, ensuring a consistent and reliable interface. This design not only enhances performance but also offers superior protection from the elements, leading to a smoother, longer-lasting ride.

This bottom bracket connects your crankarms securely, effectively translating power to your drivetrain while protecting internal components.
