CeramicSpeed BB ALPHA for PF30 30mm Road

 

The CeramicSpeed BB ALPHA for PF30 30mm Road is the flagship ceramic bottom bracket from Danish manufacturer CeramicSpeed, purpose-built for frames equipped with a PF30 press-fit bottom bracket shell (46mm bore diameter, 68mm width) paired with a 30mm spindle crankset. Featuring grade-3 Silicon Nitride ceramic balls paired with hardened stainless-steel races, custom-engineered seals refined through 28 design iterations, and precision dust covers delivering up to 500% better moisture protection, this hand-built bottom bracket weighs just 101g net — a 10% weight reduction over previous generations — and is backed by a CeramicSpeed lifetime warranty.

The BB ALPHA is a bottom bracket built to outlast your frame. CeramicSpeed has concentrated decades of ceramic bearing expertise into this flagship product, with every detail from material selection to seal architecture rigorously validated and iteratively refined.

Each BB ALPHA unit is hand-assembled by skilled 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 industries — offering exceptional hardness, superior surface smoothness, and outstanding corrosion resistance. These ceramic balls are paired with specially hardened stainless-steel races to deliver consistently ultra-low rolling friction throughout the product's lifespan.

The sealing system represents a key breakthrough in the BB ALPHA design. CeramicSpeed's engineering team developed an entirely new custom seal and precision dust cover assembly through 28 design iterations. While maintaining minimal rotational drag, this system achieves up to 500% better protection against moisture and contamination compared to previous generations. This means bearing internals remain clean and dry even when riding in wet or adverse weather conditions, dramatically extending service life.

The simplified spacer tube design reduces the number of component variants, making installation quicker and more straightforward. Simultaneously, the redesigned cup material and geometry have been optimised for strength while achieving a 10% overall weight reduction compared to the previous generation.

This model precisely pairs with frames featuring a PF30 press-fit bottom bracket shell — a pressfit 46mm bore that is 68mm wide — with bearings placed outboard, accommodating cranksets with a 30mm axle of adequate length. PF30 is a widely adopted press-fit bottom bracket standard found in road and triathlon frames from numerous prominent frame manufacturers. Installation requires a press-fit specific tool, and CeramicSpeed recommends using their dedicated Bottom Bracket Tool Kit.

All BB ALPHA products are backed by a CeramicSpeed lifetime warranty.

Important note: This product is not compatible with THM cranks.

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.

Compatibility

This product is compatible with all frames featuring the EVO386 press-fit BB standard (46mm bore, 86mm shell width), paired with 30mm axle cranksets of adequate length, with bearings placed inboard. Compatible brands include SRAM, Easton, FSA, Rotor, Cannondale, and Race Face. It is important to note that this product is not compatible with THM cranks. EVO386 is a press-fit installation standard, requiring professional bottom bracket press and removal tools. Before installation, confirm your frame's BB shell bore diameter is 46mm and shell width is 86mm, and verify that your crankset uses a 30mm axle diameter. It is recommended to consult the CeramicSpeed official Compatibility Matrix and Spacer Chart before installation to confirm suitability for your specific frame and crankset combination, and to select the correct spacer configuration.

Grade-3 Silicon Nitride Ceramic Balls (CeramicSpeed Balls)
