BB ALPHA is CeramicSpeed's latest flagship bottom bracket series, engineered with one uncompromising goal: to outlast your frame. This model is purpose-built for BBright pressfit asymmetric frames (46mm bore, 79mm shell width) paired with 30mm axle cranksets. It is suitable for road cycling, triathlon, and track disciplines.
About the BBright Standard
BBright is an asymmetric pressfit bottom bracket standard developed by Cervélo. It utilises a 46mm bore diameter (identical to PF30) but features an asymmetric shell width of 79mm — 11mm wider than the standard PF30's 68mm, with the additional width concentrated on the non-drive side. This asymmetric design allows frame engineers greater design freedom at the drive-side chainstay junction while providing improved bearing spacing on the non-drive side, contributing to enhanced frame stiffness and pedalling efficiency.
BBright uses pressfit installation, with bearing cups pressed into the frame shell via precision interference fit. Due to its wider shell compared to standard PF30, BBright frames cannot directly use standard PF30 bottom brackets — a BBright-specific model is required to ensure correct bearing positioning and crankset alignment.
Core Technology
Grade-3 Silicon Nitride Ceramic Balls (Si₃N₄) — Exceptionally high spherical precision, approximately twice the hardness of steel balls at only 41% of the density. Smoother surface and inherent corrosion resistance dramatically reduce rolling friction and inertia losses. Grade-3 designation indicates strict manufacturing tolerances ensuring top-tier roundness and dimensional consistency across every ball.
Hardened Stainless-Steel Races — Inherently corrosion-resistant at the material level, preventing rust or pitting even in wet riding conditions or humid environments. Hardening treatment ensures the races maintain precise raceway geometry under high loads such as out-of-saddle efforts or sprint forces.
Custom-Engineered Seal System (28 Iterations) — CeramicSpeed's engineering team developed precision dust covers and multi-barrier seal structures through 28 design iterations, optimising fitment and protection. Moisture and contamination protection is improved by 500% over the previous generation, while precisely controlled seal contact pressure ensures no sacrifice in rotational performance.
Simplified Spacer Tube Design — A new super-light spacer tube structure with fewer variants ensures faster, more intuitive installation. Cup material and geometry have been optimised for strength and reduced weight, achieving a 10% overall weight reduction while facilitating future maintenance.
Hand-Built in Denmark — Every BB ALPHA is individually assembled and spin-tested by technicians at CeramicSpeed's Holstebro factory, ensuring quality consistency far beyond mechanised mass production.

Compatible Frames
This product is designed for BBright pressfit asymmetric frames with a 46mm bore and 79mm shell width. BBright was developed by Cervélo and is found primarily across multiple Cervélo model lines (such as S5, R5, P5, and others), as well as select brands licensed to use this standard.
Note: BBright (asymmetric 79mm shell, 46mm bore) is a different specification from PF30 (symmetric 68mm shell, 46mm bore), BB30 (symmetric 68mm shell, bearings pressed directly without cups), and EVO386 (symmetric 86.5mm shell, 46mm bore). Although BBright and PF30 both use a 46mm bore diameter, they differ in shell width and symmetry. Using the incorrect model will result in bearing misalignment and incorrect crankset positioning. Please verify your frame's bottom bracket shell specifications before purchase.
Compatible Cranksets
All road cranksets with a 30mm axle diameter and adequate length for BBright shell width are compatible, including SRAM (Force, Red, Rival series with 30mm axle versions), Easton (EC90 series), FSA (K-Force, Energy, and other 30mm axle models), Rotor (ALDHU, VEGAST, 3D+, and other 30mm versions), Cannondale (HollowGram series 30mm versions), and Race Face (Next SL and other 30mm axle models).
Not compatible with: Shimano 24mm axle cranksets, SRAM DUB 28.99mm axle cranksets, Campagnolo Ultra-Torque 25mm axle cranksets, THM cranks (officially listed as incompatible), or any other 24mm axle cranksets.
Installation Notes
Use the correct tool: BBright is a pressfit standard requiring dedicated pressfit bottom bracket installation tools (CeramicSpeed Bottom Bracket Tool Kit recommended). Ensure cups are perfectly aligned with the frame shell during pressing — avoid angled insertion which may cause damage.
Clean the shell: Thoroughly clean the inside of the frame's bottom bracket shell before installation, removing old adhesive, residue, or metal debris.
Apply retaining compound or grease: Following your frame manufacturer's recommendations, apply appropriate retaining compound (e.g. Loctite 641) or the included UFO TECH grease to the shell interior and cup exterior to prevent creaking and ensure secure fitment.
Spacer configuration: Using the included Spacer Kit instructions and CeramicSpeed's official Spacer Chart, select the correct spacer combination to ensure proper crankset alignment and chainline.
Preload adjustment: When installing 30mm axle cranksets, use the respective brand's preload system to adjust axial play — ensure no lateral movement while maintaining smooth rotation.
Removal note: Use a dedicated removal tool when extracting pressfit bottom brackets. Never use screwdrivers or metal rods to hammer cups out, as this may damage the frame shell.
Professional installation: If unfamiliar with pressfit bottom bracket procedures, professional workshop installation is recommended. CeramicSpeed provides an official installation video covering BB ALPHA for pressfit 46mm frames, including BBright, EVO386, and PF30.

BB ALPHA vs Previous Generation
BB ALPHA surpasses the previous generation across multiple dimensions. Race material has been upgraded from stainless steel to hardened stainless steel, with moisture and contamination protection improved by 500%. Dust covers feature a precision design refined through 28 iterations, replacing the previous standard design. Weight has been reduced by 10% (net 93g), and the spacer tube uses a new simplified super-light design for more intuitive installation. The warranty has also been upgraded from a limited warranty to a lifetime warranty.
