CeramicSpeed BB ALPHA Road Bottom Bracket – Italian, 70mm, for DUB Spindle delivers the kind of precision, efficiency, and durability that dedicated road riders demand. Built to outlast the frame it’s installed in, this bottom bracket combines advanced ceramic bearing technology with thoughtful engineering for smooth, low-friction performance and long-term protection against the elements.
At the heart of the BB ALPHA are hand-built bearings featuring grade-3 Silicon Nitride ceramic balls running on hardened stainless-steel races. This pairing ensures exceptional corrosion resistance and remarkable rolling efficiency, even under high loads or in wet conditions. Improved custom seals and precision dust covers provide up to 500% better moisture protection than previous designs, keeping contaminants out and performance consistent.
A redesigned internal race supports better pre-load handling, while the simplified spacer tube and lightweight 7075 aluminum cups shave 10% off the weight compared to earlier generations. The result is a bottom bracket that installs quickly, runs smoother for longer, and maintains the performance edge serious cyclists expect from CeramicSpeed.
