CeramicSpeed BB ALPHA for T47/68 Campy UT Road

 

The CeramicSpeed BB ALPHA for T47/68 Campy UT Road is a flagship ceramic bottom bracket from Denmark, designed for frames with a T47 threaded bottom bracket shell (68mm width) paired with Campagnolo Ultra Torque cranksets (25mm axle), with bearings placed outboard. 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. Purpose-built for the Campagnolo Ultra Torque system.

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 T47 threaded bottom bracket shell measuring 68mm in width, with bearings placed outboard. The T47 standard is a modern BB standard that combines the reliability of threaded installation with the larger bore diameter advantages of oversized BB shells. The 68mm shell width is the standard width for traditional road frame geometry. Threaded installation means no pressing is required, making fitting and removal more convenient, friendlier to the frame, and significantly reducing the risk of creaking associated with poorly fitted press-fit units.

This model is purpose-built for the Campagnolo Ultra Torque (UT) crankset system. The Campagnolo Ultra Torque system features a unique 25mm split-axle design where each crank arm integrates a half-axle, joined at the centre via a Hirth joint. BB ALPHA's outboard bearing cups are precisely matched to the Ultra Torque system's installation dimensions and tolerance requirements, ensuring smooth, play-free crankset operation.

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.

T47/68 Threaded Installation (Outboard Bearings)
The T47 standard employs threaded installation, combining the large-diameter BB shell capacity with the convenience of traditional threaded bottom brackets. The 68mm shell width represents the standard road frame geometry with bearings placed outboard. Compared to press-fit designs, threaded installation is more frame-friendly, less prone to creaking, and does not require expensive dedicated press tools for fitting or removal.

Campagnolo Ultra Torque Dedicated Design
Purpose-built for the Campagnolo Ultra Torque crankset system (25mm axle), with outboard bearing cups precisely matched to the UT system's installation dimensions and tolerances. Compatible with Super Record, Record, Chorus, and other Campagnolo cranksets utilising the Ultra Torque interface.

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 a T47 standard threaded bottom bracket shell measuring 68mm in width, paired with Campagnolo Ultra Torque cranksets, with bearings placed outboard. The Campagnolo Ultra Torque system is a split-axle crankset design where each crank arm integrates a half-axle (25mm diameter), joined at the centre via a Hirth joint self-locking bolt. Ensure your frame's BB shell width measures 68mm, and confirm that your Campagnolo crankset uses the Ultra Torque interface (not Power Torque or other interfaces). T47 is a threaded standard (not press-fit), requiring a suitable bottom bracket socket tool for installation. 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.
