Angular contact ball bearings can carry on both axial and radial loads. These bearing types are not separable; therefore, they are mounted in pairs.
In a standard single row radial bearings, only 3 or 4 balls make contact when you are pedaling. But with our patented preload system, ALL balls are engaged and spread the force over a larger surface area, to decrease friction and minimize wear.
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.
Thanks to the preload, the force is distributed among all the balls using the entire raceway to distribute the load.
The unique design of a bushing to contain both the bearings and seals, allows us to control critical dimensions such as perpendicularity, roundness …
Hardness, resistance and lightness. All the advantages of the ceramic balls are transposed to our bottom bracket shafts.
Top class materials with low weight to increase the product stiffness. For a comfortable ride with the maximum performance.
