Bikone DCTech BB30 - Steel bearings - Shimano

Bikone DCTech BB30 bottom bracket (⌀42mm - Width 68 to 73mm) Pressfit with steel bearings - Shimano standard (⌀24mm)

The Bikone DCTech BB30 bottom bracket – steel bearings – Shimano is designed to accompany every kilometer with maximum smoothness, precision, and reliability. It's for cyclists who demand consistent performance, whether on the road or mountain bike, and who want to eliminate any loss of efficiency at the bottom bracket.

Thanks to the exclusive Dual Cup Technology (DC Tech) and the use of very high quality steel bearings, this bottom bracket offers quiet pedaling, without unwanted play and with excellent longevity, even when conditions become demanding.

Dual Cup technology and alignment precision

Dual Cup Technology uses two aluminum cups that perfectly align the bearings on either side of the bottom bracket shell. This design creates an extremely rigid central assembly, eliminating micro-movements, creaking, and energy loss. The result is a smoother, quieter, and more efficient pedaling experience, even under heavy load.

Bearings and protection

This housing is equipped with high-precision Chronium steel bearings, certified ABEC5/P5 – 2RS. They offer excellent wear resistance, low friction, and high durability. The entire assembly is fully sealed thanks to axial seals and complete protection of all surfaces, guaranteeing consistent performance over time, even in humid or dusty conditions.

Materials and durability

The cups are made of aircraft-grade 6061 aluminum, with a T6 heat treatment. This material offers excellent corrosion resistance and high rigidity, ensuring perfect bearing stability and long-lasting reliability.
