CeramicSpeed T47/86 Inboard 30mm Bottom Bracket

The CeramicSpeed T47/86 Inboard 30mm Bottom Bracket is designed for riders who want the lowest friction, maximum power transfer and the longest possible bearing life. Built for T47 frames using the 86mm inboard standard, it combines oversized performance with the reliability of a threaded system.

Engineered Around the T47 Standard: T47 uses a threaded interface with a 47mm inner diameter and 86mm width, blending the stiffness benefits of PF30 and EVO386 with the security of threads. T47/86 positions the bearings inside the frame and is compatible with both standard 86mm T47 frames and Trek’s 85.5mm T47 designs.

Precision-Matched Bearings for Smooth Efficiency: Each cup is factory-assembled with CeramicSpeed bearings, available in Standard or Coated versions. The Standard bearings use hardened-steel races paired with super-smooth CeramicSpeed Balls, while the Coated option adds a 3-micron metallic layer for even lower drag and significantly enhanced durability.

Optimised for 30mm Spindle Cranks: This bottom bracket is purpose-built to pair T47 frames with 30mm spindle cranksets, delivering a stiff, highly efficient interface. The oversized design ensures excellent load distribution, improved pedalling stability and ultra-smooth bearing rotation under high power.

With its threaded construction, oversized architecture and world-class CeramicSpeed bearings, it offers long-lasting performance and exceptional riding efficiency.
