Unreliable and Expensive Bearing

As my tests showed, this bearing failed to perform after only a few USES, despite its high price. The only positive was the initial smoothness before it fell apart. It's not worth the investment for a product that doesn't last. .

Pros
  • High-quality ceramic material ensures durability and longevity
Cons
  • Requires proper maintenance to avoid damage and ensure optimal performance

Not suitable for cycling.

Not a good replacement for a bicycle bottom bracket. Yes, they run very quietly, but the seals don't touch the inner ring. There is a tiny gap between the inner ring and the seal that allows water and dirt to get in fairly quickly. I installed them because I wanted my fat bike to work. And of course after a few dry runs you could hear the sand inside. God knows after you cross the creek. I hope you see what I describe in the picture.

Pros
  • Si3N4 - silicon nitride ceramic balls
Cons
  • not reliable
