Bikone DCTech BB86-92-24 Steel bottom bracket

DCTech BB86-92 Shimano is compatible with road (BB86) and mountain (BB92) bikes for Shimano cranks.

DualCupTech™
Automatically aligns bearing faces regardless of external factors. This alignment between the bearings on both sides is crucial and special care is taken in the manufacturing process to reduce this concentricity value to a minimum. The results are incredible, extremely smooth pedalling from day one.

DualCupTech™
It is not only capable of self-aligning the bearings, but creates a strong central joint without requiring threads or single-piece designs. The result after assembly is that the bottom bracket performs as a solid part and eliminates any noise or movement issues.

DualCupTech™
It can be assembled and disassembled like any other bottom bracket, without requiring special wrenches or complex instructions.

FullySealed
Every dust particle or water droplet is a potential cause of bearing noise or wear. That is why all our bottom brackets are fitted with up to five O-rings to keep dust, water, mud and moisture out of the bottom bracket.

Axial Seals
All our bearings are fitted with not one but TWO seals to protect against dust and moisture ingress. This section is crucial for maximum durability and performance of the bottom bracket.

T6 heat treatment
For most aluminium alloys: 6061, 6063 and 7075, the best heat treatment is T6. The T6 heat treatment delivers increased hardness as well as other mechanical properties such as normalisation of its grain structure. This guarantees that all our aluminium products will perform perfectly throughout their service life.
