The full ceramic bearing is a feature that is installed on many special edition Luftverk models. Both the inner and outer race as well as the balls are all full ceramic. The ball cage is made from nylon that creates a unique noise and feel.
There are absolutely no metal components to this bearing meaning it is not prone to corrosion or rust like typical steel bearings. You can easily service this bearing by using soap and water making it super convenient to maintain without harsh chemicals.
Disclaimer - because this bearing is made from ceramic, they are a bit more delicate than the average steel bearings. Take care on tighter bearing seats.
