Advanced Metallurgy: Hardened Stainless Steel Races and 500% More Protection Hand-built in Denmark, the BB ALPHA platform features premium hardened stainless steel races across the entire range, providing absolute corrosion resistance and high-load performance under severe radial forces. Operating within these specialized races are high-precision Grade-3 Silicon Nitride (Si3N4) ceramic balls. To combat volatile road and weather 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 legacy versions, fully sealing the internal rolling elements from water, mud, and road grit without introducing mechanical friction or drag penalties.
