The new Campagnolo bottom bracket has been designed to minimize friction and transform every watt into pure speed.
The Ultra Ceramic bearings with silicon nitride balls offer uncompromising smoothness, durability, and performance.

• Bottom bracket: the hidden heart of the bike, these new ceramic bearings have been designed to reduce friction and increase smoothness.
  
• ULTRA Ceramic bearings with silicon nitride balls selected according to aerospace standards for maximum roundness, surface perfection and integrity, and optimal gliding.
  
• High-performance resin inner cage: reduces friction and noise between the balls.
  
• Double seal system: internal and external protection for greater cleanliness and smoothness over time.
  
• Reduced weight: only 49g in the BSA version (3g less than in the standard version).
  
• Benefits: smoother, quieter, and more efficient pedaling.
• This results in a weight reduction of approximately 3g compared to the standard version; for example, the BSA version weighs only 49g.
