As a competition level bicycle bearing, ACER Racing's world famous 6804 ball bearings offer exceptional performance, durability, and efficiency, making them a popular choice among cyclists and bicycle enthusiasts.

The size 6804 designation refers to the bearing's dimensions, with an inner diameter of 20 millimeters, an outer diameter of 32 millimeters, and a width of 7 millimeters. These dimensions make them compatible with various bicycle components, such as hubs, bottom brackets, and headset assemblies.

Ceramic silicon nitride ball bearings provide several advantages over traditional steel bearings. Silicon nitride ceramic material offers superior hardness, reduced friction, enhanced wear resistance, and resistance to corrosion and high temperatures.

One of the primary benefits of 6804 ceramic silicon nitride cycling ball bearings is their reduced friction coefficient. Ceramic balls have a smoother and harder surface compared to steel balls, resulting in lower friction during rotation. This leads to improved efficiency, reduced rolling resistance, and enhanced power transfer, allowing cyclists to pedal more efficiently and achieve higher speeds.

Furthermore, ceramic silicon nitride bearings exhibit exceptional durability and wear resistance. They can withstand high loads, impacts, and harsh cycling conditions without premature wear or damage. The increased durability of these bearings translates into extended service life, reduced maintenance requirements, and enhanced reliability for cyclists.

Ceramic silicon nitride cycling ball bearings also demonstrate excellent corrosion resistance. They can withstand exposure to moisture, dirt, and other environmental elements commonly encountered during cycling. This corrosion resistance ensures consistent performance and longevity, even in challenging weather conditions.

Moreover, the lightweight nature of ceramic materials contributes to reducing the overall weight of the bicycle. This weight reduction can enhance acceleration, maneuverability, and overall cycling performance.

Whether used in road bikes, mountain bikes, or other cycling disciplines, 6804 ceramic silicon nitride cycling ball bearings deliver reliable and efficient performance, enhancing the overall cycling experience for riders.
