Description

The DCTech T47 external bottom bracket for Shimano cranks is designed for cyclists who demand maximum performance and durability, whether they´re hitting the rough mountain trails or enjoying the open road.
Thanks to our dual-cup technology (DC Tech) and high-quality ceramic bearings, our bottom bracket will provide you with a smooth pedaling experience.

DCTech T47 External for Shimano Features.
Double-cup technology.
Two aluminum cups perfectly align the bearings on both sides, creating a solid central connection that eliminates any noise or movement.
This bottom bracket uses steel bearings (ABEC5/P5 – 2RS).
The cups of our bottom brackets are made of 7075 aluminum, a high-strength aerospace-grade aluminum to which we apply a T6 treatment.
This makes the material harder and more durable, ensuring our cups maintain optimal performance over time.
