CeramicSpeed BB Alpha for T47a Sram DUB Road

The new CeramicSpeed Alpha BB Alåha bottom bracket is specifically developed to meet the technical requirements of modern high-performance road bikes, triathlon machines, and track bikes. This product is precision-designed to fit the asymmetric T47a standard, which is often found on high-end frames. It is compatible with frames that have a shell width of 77 millimeters and an internal diameter of the bottom bracket shell itself of 47 millimeters. When it comes to the crankset itself, this bottom bracket is created exclusively to work with the SRAM DUB system, which uses an axle diameter of exactly 28.99 millimeters. It is important to note that this solution is optimized for road disciplines where every single watt counts, and where stiffness in the transition between frame and crank is crucial for overall power transfer. By using lightweight alloy cups, the system ensures a stable and precise installation that withstands the high forces generated during sprints or sustained hard climbing on inclines. The design takes into account the asymmetric aspects of the T47a standard, ensuring a perfect chainline and optimal function without compromising the structural integrity of the frame. For the rider, this means seamless integration that combines the threaded reliability of T47 with the advanced performance of the SRAM DUB architecture, which minimizes the risk of creaking noises during riding.

Choosing a CeramicSpeed Alpha BB Alåha bottom bracket represents the absolute pinnacle of cycling technology and mechanical efficiency for serious cyclists. The heart of this product is the ceramic balls made of Grade-3 Silicon Nitride, which are significantly harder, smoother, and lighter than the standard steel balls typically found in bicycle components. These balls are paired with specially hardened stainless steel races, creating an extremely durable construction with minimal friction. One of the most impressive features of this new generation is the 10 percent weight reduction compared to previous models, bringing the total net weight down to just 101 grams for the entire unit. This is achieved through an intelligent and simplified spacer tube design and lighter alloy cups. To ensure this performance lasts under all conceivable weather conditions, the bottom bracket is equipped with specially developed seals and precision dust covers designed to provide up to 500 percent improved protection against moisture, dirt, and mud. Durability is not just a claim but is validated through extreme testing, including continuous loading with a full 3000 watts for 7 hours and more than one million test kilometers in real-world scenarios. This incredible reliability is why professional teams such as Soudal Quick-Step, PAS Racing, and Cannondale Factory Racing use CeramicSpeed in the world's most demanding races. Furthermore, the materials are chosen for their natural resistance to corrosion, ensuring that the bearings run smoothly and efficiently through many seasons, regardless of the environment.

When you receive a CeramicSpeed Alpha BB Alåha bottom bracket, you get a complete solution ready for immediate installation and long-term use on your bike. The package includes the bottom bracket itself, fitted with exclusive ceramic bearings, a specific SRAM DUB spacer kit ensuring correct axle adjustment in your frame, and a 5 milliliter container of UFO TECH All Round bearing grease. This grease is carefully tuned to the specific requirements of the ceramic bearings to maximize both speed and longevity under mixed conditions. A CeramicSpeed sticker for your bike frame is also included. A central point in the value of this product is CeramicSpeed's lifetime warranty, which fully covers this product and provides peace of mind for your investment. This warranty reflects the extreme care taken during manufacturing in Denmark, where every single component is designed to withstand the toughest loads without losing its efficiency. Installation is straightforward thanks to the threaded cups which, in accordance with the T47 standard, must be tightened to 40 Newtonmeter, as clearly indicated by the laser-etched markings on the outside of the cups. The high quality of the materials used and the advanced sealing technology minimize the need for frequent maintenance, although it is recommended to inspect the bearings after riding in particularly challenging conditions to maintain the ultra-low friction. By following the included instructions and using the correct spacers, you achieve a perfect setup that eliminates resistance and maximizes the watt output directly from the pedals to the rear wheel on your way to new personal records.
