The new DUB (29 mm) crankset standard, built on a 28.99 mm axle, allows for a bottom bracket design that is more resistant to contamination, while maintaining the efficiency and durability that characterize CYBREI bottom brackets.
With an integrated dust cover on all models , the firm and secure fit that also fully protects the bearing face offers exceptional performance without compromise.
CYBREI's handcrafted bearings transmit the load from the crank arm to the frame with unmatched durability and efficiency.
