KOGEL BEARINGS Service Kit SRAM DUB30 | Road Seals
The maintenance kit contains everything you need to carry out regular (annual) maintenance on your Kogel bottom brackets. It is suitable for all Kogel DUB bottom brackets for frame standards that are not BB86 or BB92. This set consists of four replacement seals, two dust caps, two bearing adapters and the Kogel ultra-low-friction grease to maintain a complete bottom bracket.
The folks at Kogel Bearings believe that high-quality ceramic bearings are the benchmark 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 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 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 from external weather influences: dust, water and mud. It is ideal for CX, MTB or racing bike use when maximum durability is important.
Kogel Bearings is aware that ceramic bearings have a bad reputation when it comes to durability. This is usually due to the suboptimal quality of the bearings being sold as high.
A bearing must be designed and manufactured in a balanced manner: the hardness of the balls must be combined with equally smooth and hard bearing tracks. Bearing cage, seals and greases must be coordinated with each other in order to work perfectly.
If one of the components does not fit optimally, it will reduce 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 their products, they guarantee that the bearings will run properly for at least 2 years.
If something breaks in the first year, Kogel will repair or replace the product without asking many questions.
Service is required after the first year. If the bearing is serviced by a qualified mechanic, i.e. cleaning, relubrication and replacement of the seals,
the guarantee is extended by another year.
