The CeramicSpeed BB ALPHA for T47/86 Campy UT Road is a flagship ceramic bottom bracket from Denmark, designed for frames with a T47 threaded bottom bracket shell (85-86mm width) with inboard bearing placement, paired with Campagnolo Ultra Torque cranksets (25mm 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. At just 72g net weight, with threaded installation ensuring reliable, tool-friendly fitting purpose-built for the Campagnolo Ultra Torque crankset 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 model weighs just 72g net, placing it among the lightest threaded ceramic bottom brackets in its class.
This product is designed specifically for frames with a T47 threaded bottom bracket shell that is 85-86mm wide, with bearings placed inboard. T47 is a threaded BB standard that combines the installation reliability of traditional threaded bottom brackets — cups thread securely into the frame without requiring press tools, eliminating the risk of frame damage from improper pressing force — with the bearing size advantages afforded by the larger shell bore diameter. The 85-86mm shell width is a wider BB shell specification used in certain modern road frames. The additional internal space, combined with the inboard bearing layout, provides an improved bearing spacing span for crankset axle support while allowing frame designers to achieve greater structural stiffness in the bottom bracket area. Threaded installation means cups can be precisely and securely fastened into the frame, with subsequent maintenance and removal being significantly more convenient. The inboard bearing configuration means the bearings are housed within the BB shell rather than sitting externally outside it, resulting in a cleaner, more streamlined appearance while the bearings benefit from additional protection provided by the shell itself.
This model is purpose-built for the Campagnolo Ultra Torque (Campy UT) crankset system. Campagnolo Ultra Torque is Campagnolo's distinctive crankset axle technology featuring a split 25mm diameter axle design, where each crank arm carries a half-axle that joins and locks together at the centre of the bottom bracket via a central bolt. This design enables exceptionally convenient crank installation and removal while maintaining outstanding structural rigidity. Due to Campagnolo Ultra Torque's unique axle architecture, a purpose-designed bottom bracket is required — this product is engineered precisely for that purpose.
Installation uses a threaded method. The CeramicSpeed Dual Socket Tool T45 Colnago/T47 is recommended to ensure correct torque application. Prior to installation, please consult the CeramicSpeed official Spacer Chart and Compatibility Matrix to confirm suitability for your specific frame and crankset combination.
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 72g net weight, it is among the lightest threaded ceramic bottom brackets available in 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.
T47 Threaded Installation (86mm Shell Width, Inboard Bearing Placement)
The T47 standard uses threaded installation where cups thread securely into the frame BB shell with precision threads, providing stable and reliable fitment without requiring press tools and significantly reducing the risk of frame damage during installation. Threaded connection also makes future maintenance and removal considerably easier. The 86mm shell width accommodates an inboard bearing layout where bearings sit within the BB shell rather than externally, benefitting from additional shell protection and presenting a cleaner external appearance. The wider shell provides improved bearing spacing and support. The T47 threaded standard's larger shell bore diameter accommodates larger bearings, delivering superior support and durability.
Campagnolo Ultra Torque Crankset Dedicated
Purpose-engineered for the Campagnolo Ultra Torque split 25mm axle crankset system, precisely matching Campagnolo's proprietary axle architecture and bearing specification requirements. Compatible with all Campagnolo road cranksets utilising Ultra Torque technology, including the Super Record, Record, and Chorus series.
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 threaded BB standard with a shell width of 85-86mm and inboard bearing placement, purpose-built for pairing with Campagnolo Ultra Torque cranksets. T47/86 refers to the T47 threaded standard with an 86mm (or 85mm) shell width — please confirm your frame's BB shell is T47 threaded with a shell width of 85-86mm before purchasing. This model's bearings are positioned inboard (within the BB shell), which differs from outboard configurations — please ensure you select the correct type for your frame. Campagnolo Ultra Torque employs a unique split 25mm axle design, and this product's bearing specifications and internal dimensions are engineered specifically for this architecture. Threaded installation requires appropriate torque application. The CeramicSpeed Dual Socket Tool T45 Colnago/T47 is recommended for installation and removal. 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.
