Product description
The CeramicSpeed Balls go through an extensive manufacturing process to ensure the highest material density possible, so that you do not have to worry about their longevity.
Our ‘hammer test’ video is a great testament to the quality and durability of the materials we work with for our CeramicSpeed Balls. We strive to source the highest quality races for our bearings with specially polished surfaces to best pair with our high quality CeramicSpeed Balls.
The unique manufacturing process is 4-6 times longer than many of our competitors. This results in a ball that not only exceeds the standard ‘Grade 3’ specifications but is of a higher density & hardness through to the center of the ball.It is specifically this hardness of the ball that allows it to maintain the surface smoothness from manufacturing (measured to 0.08 microns, or 0.00008 mm for surface measurement).
400% smoother, 128% harder and 58% lighter than standard steel balls normally used in the bicycle industry.
Grade 3 Silicon Nitride making them second to none
