KOGEL BEARINGS bottom bracket BSA for SRAM DUB | Road Seals ceramic
In 2013, Ard Kessels founded the Kogel Bearings brand in El Paso, Texas, with the aim of producing high-end bearings that fit a premium bike.
If you want to build the best bearings, there is no way around silicon nitride. This material has a number of material properties that make it almost perfect for bicycle bearings.
The material is extremely hard, wear resistant, can be formed into perfectly round balls with minimal tolerances and can be polished smoother than any metal. In addition, the material does not rust or corrode in any other way.
The bearing rings are made of hardened steel and polished. This is necessary to create a perfectly 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 for the smoothest possible running.
The Cross Seals, on the other hand, are designed for additional protection against external weather influences: Dust, water and mud. They are ideal for CX, MTB or road bike use where maximum durability is important.
Kogel Bearings is aware that ceramic bearings have a poor reputation in terms of durability. This is mostly due to the fact that suboptimal bearing quality is sold as high quality.
A bearing must be designed and manufactured in a balanced way: the hardness of the balls must be combined with equally smooth and hard bearing races. The bearing cage, seals and greases must be matched in order to work perfectly.
If one of the components does not fit perfectly, it reduces the performance of the entire bearing. The result is increased resistance, a shortened service life or even 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, no questions asked.
After the first year, a service must be carried out. If the bearing is serviced by a qualified mechanic, i.e. cleaned, relubricated and the seals replaced,
the warranty is extended by a further year.
With this bottom bracket you can use your SRAM DUB crank in a frame with BSA standard. This bearing is also available with the Cross Seals(32409).
