The CeramicSpeed 61803 (6803) bearings are meticulously hand-built in Denmark, incorporating advanced silicon nitride balls that surpass standard steel bearings in smoothness, hardness, and weight. These bearings are designed to provide a significant reduction in friction, improving power transfer and extending the lifespan of cycling components.
Engineered with a reinforced polyamide cage and optimized with low viscosity “Blue Grease,” these bearings are protected by non-contact seals to keep out dirt and moisture, making them suitable for various cycling disciplines including Road, TT, Tri, Track, Cross, and MTB.
- 400% smoother, 128% harder, and 58% lighter than standard steel bearings
- Hand-checked four times during the building process for precision and performance
- Designed to handle 99% higher loads compared to other ceramic balls
