Technologies

DualCupTech™
DualCupTech™ automatically aligns the bearing surfaces regardless of external factors. Alignment between the bearings on both sides is crucial, and particular care is taken during production to minimise this concentricity value. The result is incredible: exceptionally smooth pedalling from day one. DualCupTech™ can not only self-align the bearings but also creates a solid central joint without requiring threads or a single-piece design. Once assembled, the bottom bracket works as a solid unit and eliminates any noise or movement issues. DualCupTech™ can be fitted and removed like any other bottom bracket, without special spanners or complex instructions.

Ceramic ball bearings
An experienced manufacturer of high-performance bearings. Ceramic ball bearings offer superior corrosion resistance, greater dimensional stability, lower density and greater heat resistance. All this results in a more efficient material for bottom brackets.

Fully sealed
Every particle of dust or drop of water is a potential cause of bearing noise or wear. That is why all bottom brackets feature up to five O-rings to keep dust, water, mud and moisture out of the bottom bracket.

Axial seals
All bearings feature not one but DUE seals to protect against dust and moisture. This section is essential to ensure maximum bottom bracket life and performance.

6061-T6 Aluminium
Aerospace quality and precision in one of the strongest woods. Bikone has also developed a particularly scratch-resistant matt anodised finish worthy of any art gallery.

T6 Heat treatment
For most aluminium alloys: 6061, 6063 and 7075, the best heat treatment is T6. T6 heat treatment ensures greater hardness and other mechanical properties, such as normalisation of the grain structure. This ensures that all aluminium products perform perfectly throughout their service life.

Note: for correct compatibility, MTB cranks must always be fitted to MTB frames and road cranks to road frames.
