Ceramic Speed coated bearings are a true technological masterpiece, providing an incredible advantage. Compared to standard bearings, they open new possibilities for both professionals and enthusiasts. Here are the main advantages of coated bearings, clearly and understandably:

High resistance: With a metallic coating, Ceramic Speed coated bearings are 75% harder than standard steel bearings. Hardness here is the key to longevity and reliability – these bearings can withstand significantly higher usage intensity and pressure, giving cyclists peace of mind even under the most extreme riding conditions.
Corrosion protection: One of the biggest challenges for any bicycle part is protection against corrosion, which can be caused by contact with water, dirt, or even cleaners. Ceramic Speed coated bearings feature exceptional corrosion resistance, making them an ideal choice not only for daily use but also for extreme conditions, such as riding on muddy trails or in the rain.
Lower friction: Friction is a key factor determining the efficiency of bearings. Lower friction means less energy wastage and, correspondingly, greater efficiency. Ceramic Speed coated bearings ensure an extremely low level of friction, giving the cyclist the ability to achieve the best results with less effort.
Lifetime warranty: The manufacturer's lifetime warranty is not only a mark of confidence in their product but also provides additional value and peace of mind for the user. This warranty indicates that by purchasing these bearings, you can be sure of their reliability and longevity.
Durability under tough conditions: Even under the toughest conditions, such as exposure to water or dirt, Ceramic Speed coated bearings maintain their characteristics thanks to the advanced coating. This means that their performance and longevity remain at the highest level regardless of external factors.

Ceramic Speed coated bearings are not just a high-quality choice for your bicycle, but also an investment in smoother, more efficient, and longer-lasting performance. Whether in daily commutes or competitions, these bearings provide the cyclist with an advantage and the highest level of reliability.
