Advanced Metallurgy: Hardened Stainless Steel Races and Ceramic Bearings Hand-built in Denmark, the BB ALPHA platform utilizes high-grade hardened stainless steel races across the entire range, delivering complete corrosion resistance and structural integrity under severe radial and axial forces. Operating within these races are ultra-precise Grade-3 Silicon Nitride (Si3N4) ceramic balls. To combat harsh riding environments, CeramicSpeed developed custom light-contact seals paired with protective dust covers refined over 28 design iterations. This system provides a staggering 500% increase in moisture and contamination protection compared to legacy versions, sealing the internal mechanism against water, mud, and road grit without introducing any mechanical friction penalties.
