At Kogel Bearings, they believe ceramic bearings set the gold standard for bottom brackets, derailleur pulleys and wheel bearings. The ceramic material used, Silicon Nitride, is hard and wear resistant, and will not rust or oxidize. It can be precision machined into perfectly round balls with super tight tolerances and polished smoother than any metal, making it perfect for bicycle bearings.

  • Ceramic bearings provide optimum drivetrain efficiency.
  • Precision machined components ensure a smooth, squeak-free ride.
  • Bomb-proof, all-weather seals to keep you riding no matter what.

Oversized Pulleys (12T top/14T bottom) are suitable for all of the latest generation Shimano Road derailleurs: Dura Ace R9100, Ultegra R8000 and 105 R7000.

Currently only available in road seals.

Ready to take your efficiency over long distances to new heights? The Kogel Hybrid Ceramic Road Seal jockey wheels take friction to new lows, allowing you to spin for longer without any extra effort. These jockey wheels are perfect for discerning road riders and racers tweaking the fine details to make a big difference. 

The hybrid jockey wheels are constructed with ceramic bearings, but not a ceramic housing, and therefore require lubricant to protect them and prolong their life. This means they do not initially spin as freely as full ceramic jockey wheels (which contain no lubricant), but offer a vast improvement over standard jockey wheels.
