OVERSIZED BOTTOM BRACKETS

We all know the problems that this part of the bicycle can cause, sometimes the frames can wear out with the use and get oversized.. There was no solution for this type of issue, until now! If your bottom bracket goes in too smoothly even by hand, maybe it's time to switch to the only oversized bottom bracket on the market with Bikone

MAKE IT SIMPLE, MAKE IT RELIABLE

Our exclusive double-cup system provides a perfect perpendicularity between bearings in bottom brackets. Frames with a lower tolerance may cause friction and durability issues. This results in a poor lifespan and high friction issues. This double-cup system guarantees that bearings will be perfectly balanced even in these cases.
Easy to install and remove, with only two superimposed parts.
The central part is fixed by the tight contact of both aluminium cups. This ensures maximum precision and protection against moisture and corrosion

HIGH-QUALITY MANUFACTURING PROCESS

Our quality standards are key in offering high-performance services and products. That is why our quality department is of vital importance in both manufacturing processes and communication among our employees.

HARDER – LIGHTER – MORE RESISTANT

High-performance bearing experts. Ceramic ball bearings offer a superior corrosion resistance, greater dimensional stability, lower density, higher heat resistance. All this translates into a more efficient material for bottom brackets.

TOP CLASS 6061 ALUMINIUM ALLOY

We choose top class 6061 Aluminium alloy is classed as a very high strength aluminium aerospace alloy with superior stress corrosion resistance.

TOP CLASS 7075 ALUMINIUM ALLOY

We choose top class 7075 Aluminium alloy is classed as a very high strength aluminium aerospace alloy with superior stress corrosion resistance.

STABLE PRELOAD FOR MAXIMUM PERFORMANCE

The amount of preload to be applied during the assembly has been determined carefully, taking into account several factors such as the required rigidity of the assembly, bearing life, friction of the bearing, as well as the load to be applied from the cyclist.

T6 HEAT TREATMENT

For most aluminum alloys: 6061, 6063 and 7075, the best heat treatment is T6. The T6 heat treatment offers an increase in hardness and other mechanical properties such as the normalization of its granular structure. In this way, we guarantee that all our aluminum products will behave perfectly throughout their useful life.

OPTIMAL USE OF BALL BEARINGS

Loads supported by the bearings in the bottom bracket are transmitted from the spindle through the balls. In normal cartridge bearings, the lower balls are the ones that support the entire load. Our patented POWER SET® system ensures all balls support equal loads. Thus, guaranteeing a smooth pedalling and a greater durability of bottom bracket bearings.

+ STIFFNESS + DURABILITY + SMOOTHNESS

Angular contact ball bearings support both axial and radial loads. These bearing types cannot be separated; therefore, they are mounted in pairs.
In a standard single row radial ball bearing, only 3 or 4 balls make contact when pedalling. But with our patented preload system, all balls are engaged, spreading force over a larger surface, decreasing friction, and minimising wear
