CeramicSpeed BB ALPHA Kranksboks for T47/68 Shimano Road

The CeramicSpeed BB ALPHA bottom bracket is specifically developed to create a precise and optimized connection between a 24 mm spindle and a frame with the T47 threaded standard. This specific model is designed for frames with a bottom bracket shell width of 68 mm, which is the standard for most modern threaded road bikes. It is fully compatible with cranksets from Shimano as well as other brands using a 24 mm spindle diameter, making it highly versatile for riders seeking an upgrade. This makes it an ideal choice for demanding riders in the disciplines of road, triathlon, and track cycling, where maximum efficiency and absolute reliability are crucial for results. The design includes a significantly simplified spacer tube construction and lighter cups made from a special alloy, which not only significantly eases the installation process for the mechanic but also results in a total weight reduction of 10% compared to previous bottom bracket solutions from the manufacturer. With a net weight of only 115 grams, this bottom bracket offers a pure lightweight solution for the bike without compromising on the necessary strength or stiffness of the overall construction. By using this bottom bracket, you ensure that the power transfer from the pedals occurs with the least possible loss, which is essential for both professional athletes and serious enthusiasts who want the absolute finest equipment for their T47 frame.

The core of the CeramicSpeed BB ALPHA bottom bracket is the advanced bearings, which are painstakingly hand-built with hardened stainless steel races and the finest Silicon Nitride (grade 3) ceramic balls. These materials are carefully selected to achieve extremely low friction and exceptional resistance to corrosion in all environments. The ceramic balls are significantly harder, smoother, and lighter than traditional steel balls, which drastically minimizes rolling resistance inside the bottom bracket itself under load. To document performance and mechanical durability, CeramicSpeed has conducted extremely extensive testing programs, including over a million documented test kilometers on the road as well as continuous load tests at 3000 watts for seven full hours without stopping. This extreme validation ensures that the bearings can withstand the highest demands from professional World Tour riders under the most demanding competition conditions in the world. In practice, the ultra-low friction means that more of the rider's precious energy is converted directly into forward speed instead of being lost as useless heat in the bearings. In addition to the purely mechanical advantage, the stainless races provide an extremely long lifespan, even when cycling under challenging and wet weather conditions. The combination of high-tech materials and precise Danish engineering results in a component that delivers maximum performance pedal stroke after pedal stroke, whether you are riding a fast time trial or participating in long, grueling training rides.

The durability of the CeramicSpeed BB ALPHA bottom bracket is supported by a series of innovative technical solutions that effectively protect the vital internal parts from external elements. One of the most significant technical improvements in this series is the introduction of specially developed seals and precision dust covers, which follow a new, uniform standard across products for easier maintenance. This advanced system provides up to 500% better protection against the ingress of moisture, water, and dirt compared to traditional standard solutions, without increasing friction in the system or inhibiting rotation in any way. To ensure optimal maintenance from the start, each individual bottom bracket comes with a 5 ml tube of UFO TECH All Round Bearing Grease, which is specially formulated to work in perfect harmony with the ceramic bearings and provide maximum protection against moisture ingress and wear over time. The simplified construction of the cups also makes it significantly easier for the user or mechanic to service the bottom bracket, which is a key factor in significantly extending its lifespan during daily use. As ultimate proof of the product's extreme quality and the manufacturer's great confidence in their own craftsmanship, this bottom bracket is covered by CeramicSpeed's comprehensive lifetime warranty. This gives the individual owner invaluable peace of mind that this investment in high-end cycling equipment is fully protected against any manufacturing defects throughout the product's lifespan. With regular maintenance and correct installation, this bottom bracket will remain a completely reliable and high-performance part of the bike for many years to come, regardless of whether it is daily exposed to rain, fine road dust, or the constant vibrations from the surface while riding on both rough asphalt and indoor tracks.
