CeramicSpeed T47/68 Outboard Bottom Bracket - Shimano | Coated

What Makes the CeramicSpeed T47/68 the Best Threaded BB?

The CeramicSpeed T47/68 Outboard Bottom Bracket gives you the best of both worlds: the oversized bearing interface of PF30 and EVO386 standards with the reliability and serviceability of a threaded shell. T47 was designed by custom frame builders to solve the creaking and press-fit headaches that plague performance cyclists, and CeramicSpeed executes it with hand-built bearings that reduce friction and outlast conventional steel bearings by a wide margin. Compatible with 68mm T47 Outboard frames and Shimano cranks, this is the bottom bracket for riders who want maximum drivetrain efficiency without sacrificing long-term durability.

Two bearing configurations are available for this bracket. The Standard option uses CeramicSpeed ceramic balls running on hardened-steel races for exceptional smoothness and longevity. The Coated Bearing adds a 3-micron coating over those hardened races, reducing friction even further while increasing surface durability for riders logging serious miles in mixed conditions. Both versions are built to exacting tolerances at CeramicSpeed's Denmark facility and backed by their industry-leading warranty, making the T47/68 the smart long-term investment for Shimano-equipped road or gravel bikes.
