CeramicSpeed T47/68 External Shimano 24mm Bottom Bracket - Coated
The CeramicSpeed T47/68 External Shimano 24mm Bottom Bracket is designed for frames with a 68mm wide T47 Outboard shell, combining the oversized stiffness of PF30 and EVO386 with the creak-free reliability of a threaded interface. Originally developed by custom frame builders, the T47 standard features a 47mm inner diameter and threaded cups for secure installation and long-term performance.
This bottom bracket places the bearings outside the frame shell, making it ideal for road, gravel, and cyclocross bikes using the T47/68 outboard standard. The oversized design improves power transfer and stiffness, while the threaded interface ensures easier maintenance and a more dependable fit.
Coated bearings feature ultra-smooth CeramicSpeed balls and hardened-steel races, offering low friction and long-lasting performance. It also includes a 3-micron-thick metallic coating on the races for increased durability, reduced drag, and extended lifespan—ideal for riders seeking maximum efficiency and reliability.
