The CeramicSpeed BB ALPHA bottom bracket represents a revolution in durability and performance for road cyclists. Designed with the ambition to last longer than the bike frame itself, this bottom bracket combines state-of-the-art materials with precise processing.

Key features:

  • Hardened stainless steel races manually assembled with Grade 3 Silicon Nitride ceramic balls
  • 500% better moisture protection thanks to specially designed sealing rings and precise dust covers
  • Ultra-low friction ensuring maximum performance and efficiency
  • 10% lower weight compared to the previous generation
  • Simplified construction of spacers and lighter cups for quick installation
  • Lifetime warranty

This bottom bracket is precisely designed for combination with 30 mm spindle cranks of suitable length and simultaneously for threaded T47 frames, which are asymmetrical with a width of 77 mm. The package includes a complete Spacer Kit, universal UFO All Round Grease 5 ml, and a sticker.

An investment in quality that will last the entire life of your bike while providing premium performance with every pedal stroke.

CeramicSpeed is a Danish brand that specializes in high-performance ceramic bearings and drive components for various industries including cycling, automotive and industrial applications. The brand is known for its innovative and cutting-edge technology, offering products that aim to improve the efficiency, durability, and overall performance of mechanical systems. CeramicSpeed was founded in 2004 by Jacob Csizmadia, a mechanical engineer with a passion for cycling.

He began experimenting with ceramic materials, which are known for their low friction and high wear resistance. After years of research and development, CeramicSpeed was born.
