CeramicSpeed BB ALPHA Road Bottom Bracket - T47, 86mm, For 30mm Spindle is built for riders who demand lasting performance, low friction, and precision fit. Designed to outlast the frame it’s installed in, this bottom bracket combines advanced materials and meticulous craftsmanship to deliver smoother pedaling and long-term reliability.

Hand-built in Denmark, the BB ALPHA features hardened stainless-steel races paired with grade-3 Silicon Nitride ceramic balls for exceptional efficiency and corrosion resistance. The new design relocates the bearings farther outward, improving stiffness and load distribution while keeping contaminants out thanks to redesigned POM plastic dust covers and custom-engineered seals. A simplified spacer tube and lightweight 7075 aluminum cups make installation easier and reduce overall weight by 10% compared to the previous version.

• Ultra-low friction performance from hand-built ceramic bearings for smoother, more efficient pedal strokes.
