Ceramicspeed Alpha T47A Shimano Gravel Bottom Bracket

CeramicSpeed BB Alpha T47a Gravel Bottom Bracket 30mm, Shimano, and SRAM DUB.

CeramicSpeed started the development project by using their current bottom bracket as a benchmark and isolating all elements that make up the design. CeramicSpeed looked at each part in detail as a potential for improvement. The following criteria were set for the project:
- To make the new BB lighter
- To make it even more durable
- To enhance simplicity in the design
- To not compromise on friction reduction
The new BB ALPHA delivers the trademark CeramicSpeed low-friction performance, while boosting durability and introducing a simplified user experience across the product range. The BB ALPHA is in essence:
- Hardened stainless steel races for maximum corrosion resistance and exceptional durability
- Same high quality CeramicSpeed ball
- New light contact seals for 500% increased protection without additional drag
- Improved dustcover design for increased longevity and reduced maintenance 24 and 30 mm are 10% lighter across the range
- Optimised DUB specific cups for optimal setup with fewer spacers
- Lighter weight spacer tube design, simplified range to 1-piece or a 2-piece sleeve construction
Testing:
- More than 1.000.000 test km covered in the lab and field
- Repeated max load testing conducted at 3000 watts for 7 hours straight
- Extensive field testing in competition and training by Soudal Quick-Step (Road), gravel athletes from PAS Racing, Yeti-Fox Factory Racing (Enduro), and Cannondale Factory Racing (XC)
