The CeramicSpeed BB ALPHA for EVO386 30mm Road is a flagship ceramic bottom bracket from Denmark, designed for frames with an EVO386 press-fit bottom bracket shell (46mm bore, 86mm width) paired with 30mm axle cranksets, with bearings placed inboard. 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. Compatible with SRAM, Easton, FSA, Rotor, Cannondale, and Race Face 30mm axle cranksets.
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 an EVO386 press-fit bottom bracket shell. EVO386 is a press-fit BB standard featuring a 46mm bore diameter and 86mm shell width, with bearings placed inboard. The EVO386 standard is commonly found on high-end road frames, where the wider shell design provides greater structural rigidity for the frame while accommodating 30mm large-diameter axle cranksets to enhance pedalling efficiency. Press-fit installation involves pressing the bearing cups directly into the frame shell, requiring professional press tools to ensure precise alignment.
This model is compatible with all cranksets featuring a 30mm axle of adequate length, including those from SRAM, Easton, FSA, Rotor, Cannondale, and Race Face. It is important to note that this product is not compatible with THM cranks.
A Spacer Kit is included to allow axial clearance adjustment for your specific frame and crankset combination, ensuring a play-free and smooth-running crankset system. Prior to installation, please consult the CeramicSpeed official Spacer Chart and Compatibility Matrix to confirm suitability for your specific setup and select the correct spacer configuration.
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. At just 84g net weight, it is exceptionally light among press-fit ceramic bottom brackets of its class.
Super-Light Spacer Tube Design
The simplified spacer system achieves greater versatility and installation convenience with fewer part variants, while further reducing weight.
EVO386 Press-Fit Installation (Inboard Bearings)
The EVO386 standard employs a 46mm bore press-fit shell measuring 86mm in width, with bearings placed inboard. The wider shell design provides greater structural rigidity and wider bearing spacing, contributing to improved stability and efficiency of the entire drivetrain system. Press-fit installation requires professional tools to ensure precise cup alignment.
Multi-Brand 30mm Axle Crankset Compatibility
Broadly compatible with 30mm axle road cranksets from major brands including SRAM, Easton, FSA, Rotor, Cannondale, and Race Face. This covers a wide range of high-end to mid-range crankset systems across multiple brands to suit various rider preferences. Please note this product is not compatible with THM cranks.
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.
