CeramicSpeed BB ALPHA for T47/68 30mm Road

 

The CeramicSpeed BB ALPHA for T47/68 30mm Road is the flagship ceramic bottom bracket from Danish manufacturer CeramicSpeed, purpose-built for frames equipped with a threaded T47 bottom bracket shell (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 109g net — a 10% weight reduction over previous generations — and is backed by a CeramicSpeed lifetime warranty. The T47 threaded interface combines the installation simplicity of traditional threaded bottom brackets with the performance benefits of larger bearings, and is compatible with SRAM, Easton, FSA, Rotor, Cannondale, and Race Face cranksets.

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 is specifically designed for frames featuring a threaded T47 bottom bracket shell that is 68mm wide, with bearings placed outboard, accommodating cranksets with a 30mm axle of adequate length. The T47 standard combines the installation convenience and serviceability advantages of traditional threaded bottom brackets with a larger shell inner diameter to accommodate bigger bearings, delivering superior performance and durability. This standard has been increasingly adopted by premium road, triathlon, and track frame manufacturers in recent years. The threaded installation requires no press-fit tools, making installation and removal significantly more convenient, while also eliminating the creaking issues sometimes associated with press-fit bottom brackets. CeramicSpeed recommends using their Dual Socket Tool T45 Colnago/T47 for installation.

This product offers broad compatibility with major 30mm spindle crankset brands including SRAM, Easton, FSA, Rotor, Cannondale, and Race Face, providing excellent flexibility for frame builds and upgrades.

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

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

Grade-3 Silicon Nitride Ceramic Balls (CeramicSpeed Balls)
Manufactured from aerospace-grade Silicon Nitride, these ceramic balls offer exceptional hardness and superior surface finish, dramatically reducing rolling friction while significantly extending bearing lifespan. Compared to traditional steel balls, they are lighter, have a lower coefficient of thermal expansion, and exhibit far greater corrosion resistance.

Hardened Stainless-Steel Races
The races undergo a special hardening process for outstanding wear resistance. The stainless-steel material is inherently corrosion resistant by design, ensuring stable ultra-low friction performance throughout extended use regardless of environmental conditions.

500% Moisture Protection Improvement
The custom-engineered sealing system has been proven in testing to deliver up to 500% better protection against moisture and contamination versus previous generations, dramatically extending bearing service life across all riding conditions.

Precision Dust Covers — 28 Design Iterations
Custom-designed dust covers have been refined through 28 iterative design cycles to achieve optimal balance between precise fitment and maximum protection, effectively preventing water, dust, and contaminants from reaching the bearing internals.

Lightweight Cup Design
Cup material and structural geometry have been re-engineered to optimise strength while achieving weight reduction targets, resulting in a 10% overall weight saving compared to previous generations.

Super Light Simplified Spacer Tube Design
The new spacer tube system achieves greater universality and installation convenience with fewer component variants, reducing installation complexity while further minimising weight.

T47 Threaded Installation Advantage
The T47 threaded standard merges the installation simplicity of traditional threaded bottom brackets with the high-performance benefits of larger bearings. No press-fit tools are required for installation or removal, making future servicing significantly more convenient while eliminating the creaking issues sometimes associated with press-fit bottom brackets.

Broad Crankset Compatibility
Compatible with SRAM, Easton, FSA, Rotor, Cannondale, and Race Face 30mm spindle cranksets, providing excellent flexibility for frame builds and component configurations.

Lifetime Warranty
All BB ALPHA products are covered by the CeramicSpeed lifetime warranty. Simply follow official guidelines for correct installation and maintenance to benefit from lifetime warranty coverage.

Hand-Built in Denmark
Every bearing unit is individually hand-assembled and quality-inspected by skilled technicians at the CeramicSpeed facility in Holstebro, Denmark, ensuring each product leaving the factory meets the highest quality standards.

Serviceable Design
The BB ALPHA is built with serviceability in mind, allowing users to clean and re-lubricate bearings as needed to extend product lifespan and reduce overall replacement frequency.
