The CeramicSpeed BB ALPHA for PF30 SRAM DUB Road is a flagship ceramic bottom bracket from Denmark, designed for PF30 press-fit frames (46mm bore, 68mm shell width, outboard bearings) paired with SRAM DUB cranksets (28.99mm axle). Featuring grade-3 Silicon Nitride ceramic balls with hardened stainless-steel races, a 28-iteration seal design delivering 500% improved moisture protection, hand-built in Denmark, and backed by a lifetime warranty.
BB ALPHA is a bottom bracket built to outlast your frame. CeramicSpeed has distilled decades of ceramic bearing expertise into this flagship product, with every detail from material selection to sealing architecture rigorously tested and optimised.
Each BB ALPHA unit is hand-assembled by specialist technicians at the CeramicSpeed factory in Holstebro, Denmark. At its core are grade-3 Silicon Nitride ceramic balls — a high-performance material widely used in aerospace and precision engineering, offering exceptional hardness, superior surface finish, and outstanding corrosion resistance. These ceramic balls are paired with specially hardened stainless-steel races to deliver consistent, ultra-low rolling friction.
The sealing system represents a major breakthrough for BB ALPHA. The CeramicSpeed engineering team developed a custom seal and precision dust cover combination through 28 design iterations, achieving up to 500% better moisture and contamination protection compared to previous generations while maintaining minimal rotational drag. This means the bearing internals remain clean and dry even when riding in wet or harsh weather conditions, significantly extending service life.
The newly simplified spacer tube design reduces part count, making installation quicker and more straightforward. Meanwhile, the redesigned cup material and structure achieve a 10% weight reduction over previous generations, offering a meaningful advantage in weight-critical racing applications.
This product is designed specifically for frames with a PF30 press-fit bottom bracket shell. The PF30 standard specifies a 46mm inner bore diameter with a 68mm shell width, with bearings installed in an outboard configuration. This model is purpose-built for the SRAM DUB crankset system, which features a 28.99mm axle diameter — SRAM's universal spindle standard designed to unify compatibility across different BB standards. All BB ALPHA products are backed by the CeramicSpeed Lifetime Warranty.
Key Features
Grade-3 Silicon Nitride Ceramic Balls (CeramicSpeed Balls)
Manufactured from aerospace-grade Silicon Nitride, these balls offer exceptional hardness and superior surface finish, dramatically reducing rolling friction and significantly extending bearing service life. Compared to traditional steel balls, ceramic balls are lighter, have a lower thermal expansion coefficient, and offer superior corrosion resistance.
Hardened Stainless-Steel Races
The races undergo a special hardening treatment for outstanding wear and corrosion resistance. The stainless-steel material is inherently corrosion resistant by design, ensuring stable ultra-low friction performance over extended use.
28-Iteration Precision Dust Covers
Custom-designed dust covers refined through 28 design iterations achieve the optimal balance between fitment and protection, effectively blocking external contaminants from entering the bearing interior.
500% Moisture Protection Improvement
The custom-engineered sealing system has been laboratory-tested and proven to deliver 500% better protection against moisture and contamination versus previous generations, significantly extending bearing lifespan across all weather conditions.
Lightweight Cup Design
Cup material and structure have been redesigned and optimised to achieve weight reduction while maintaining adequate strength, delivering a 10% overall weight saving compared to previous generations.
Super-Light Spacer Tube Design
The simplified spacer system achieves greater versatility and installation convenience with fewer part variants, while further reducing weight.
Purpose-Built for SRAM DUB
Precision-engineered for the SRAM DUB 28.99mm axle specification, ensuring a perfect match with SRAM DUB crankset systems, eliminating unnecessary play and misalignment, and delivering optimal drivetrain efficiency.
Lifetime Warranty
All BB ALPHA products are covered by the CeramicSpeed Lifetime Warranty, safeguarding your investment for the long term. Simply install and maintain according to official guidelines to enjoy lifetime warranty coverage.
Hand-Built in Denmark
Every bearing is individually assembled and quality-inspected by specialist technicians at the CeramicSpeed factory in Holstebro, Denmark, ensuring every unit shipped meets the highest standards.
