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, offering total corrosion resistance and high-load performance under severe radial forces. Operating within these specialized races are premium Grade-3 Silicon Nitride (Si3N4) ceramic balls. To combat volatile road environments, CeramicSpeed engineered custom light-contact seals paired with structural dust covers perfected over 28 design iterations. This advanced barrier setup provides a staggering 500% increase in moisture and contamination protection compared to previous designs, fully sealing the internal rolling elements from water and road grit without introducing any mechanical friction or drag penalties.
