The Bikone DCTech BB30 bottom bracket – steel bearings – SRAM DUB is designed to offer maximum efficiency and unwavering reliability, mile after mile. Created for demanding cyclists, it's ideal for both road and mountain bikers looking for smooth, quiet, and durable pedaling in all conditions.

Thanks to the exclusive Dual Cup Technology (DC Tech) combined with high-precision steel bearings, this bottom bracket ensures perfect axle alignment, eliminates unwanted play and optimizes power transmission with every pedal stroke.

Dual Cup technology and mechanical efficiency

Dual Cup Technology uses two aluminum cups that keep the bearings perfectly aligned on either side of the housing. This design creates a rigid central junction, eliminates noise and micro-movements, and ensures smooth and stable rotation, even under heavy loads.

Bearings and Sealing

This case is equipped with high-precision Chronium steel bearings, certified ABEC5/P5 – 2RS. They offer excellent wear resistance, low friction, and a long lifespan. The entire assembly is fully protected by axial seals and complete sealing, ensuring consistent performance over time.

Materials and construction

The cups are machined from aircraft-grade 6061 aluminum, with a T6 heat treatment that improves hardness, corrosion resistance and overall durability of the housing.
