CeramicSpeed Alpha T47a bottom bracket: long-lasting performance and superior protection

CeramicSpeed’s BB ALPHA bottom bracket is a solution built to outlast the frame itself. The hardened stainless steel races are hand-built with grade 3 silicon nitride ceramic balls, delivering up to 500% better moisture protection than traditional models. Custom seals and precision dust covers maintain very low-friction performance over time, even in demanding environmental conditions. This innovative design ensures consistent reliability for riders seeking professional-grade components.

The streamlined spacer tube and reduced-weight cups deliver a 10% weight reduction versus previous generations, without compromising structural stiffness. Quick installation is supported by the optimized design, allowing even riders with intermediate technical skills to complete assembly without difficulty. Precise compatibility with SRAM DUB cranksets with a 28.99 mm spindle and 77 mm asymmetric T47 threaded frames ensures a perfect fit. All models benefit from a lifetime warranty, confirming CeramicSpeed’s commitment to durability.
