KOGEL BEARINGS bottom bracket PF30-L | Cross Seals ceramic 30 mm shaft
The people at Kogel Bearings believe that high quality ceramic bearings are the measure of all things for ball bearings in bicycles.
Silicon nitride has a number of material properties that make it almost perfect for bicycle bearings.
The material is extremely hard, wear-resistant, can be shaped into perfectly round balls with minimal tolerances and can be polished smoother than any metal. In addition, the material will not rust or corrode in any other way.
The bearing rings are made of hardened steel and polished. This is necessary to create a perfect, smooth running surface for the ceramic balls.
Kogel Bearings offers two different types of seals for different applications: Road Seals, a minimal contact seal designed to run as smoothly as possible.
The Cross Seals, on the other hand, are designed for additional protection against external weather conditions: dust, water and mud. It is ideal for CX, MTB or racing bike use when a maximum service life is important.
Kogel Bearings is aware that ceramic bearings have a bad reputation for durability. This is mostly due to the sub-optimal quality of the bearings being sold as a high one.
A bearing must be designed and manufactured in a balanced way: the degree of hardness of the balls must be combined with equally smooth and hard bearing tracks. The bearing cage, seals and greases have to be coordinated to work perfectly.
If one of the components does not fit optimally, it will degrade the performance of the entire warehouse. The result is increased resistance, a shortened service life or even a total failure of the bearing.
To prove that Kogel Bearings believes in its products, they guarantee that the bearings will run flawlessly for at least 2 years.
If something breaks in the first year, Kogel will repair or replace the product without asking too many questions.
A service must be carried out after the first year. If the bearing is serviced by a qualified mechanic, i.e. if it is cleaned, relubricated and the seals are replaced,
the guarantee is extended by another year.
With this bottom bracket, BB30 cranks (long shaft) fit into PF 30 frames. It is also suitable for BBRight frames if a BBRight-specific crank from Rotor or FSA is installed at the factory. It is essential to check whether this is the case before buying. The version of the PF 30 bearing offered here has a smaller offset to avoid problems with internal brake lines, Bowden cables or Di2 cables as can occur with some aluminum frames, the Cannondale SuperSix and the Cervelo P5.
