Ceramic Speed Bottom Bracket - T47 Alpha

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
