The CeramicSpeed ​​BB ALPHA BSA Road bottom bracket is designed for skinny bikes with English thread (BSA) in combination with cranks with a 30 mm axle of appropriate length. It uses hardened stainless steel rings and grade 3 Silicon Nitride ceramic balls, which are designed to achieve very low friction and high durability in harsh conditions. With custom seals and precision caps, the center is optimized for moisture protection while maintaining smooth operation. A simpler spacer tube design and lightweight cups shorten assembly time and reduce overall weight compared to the previous generation. All CeramicSpeed ​​BB ALPHA bottom brackets are covered by a lifetime warranty.
