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.
Weighing just 19g and spinning up to 10 times longer than the market leader of ceramic/titanium jockey wheels, the Kogel Full Ceramic Road Seal Jockey Wheels are the ideal option for discerning road racers who yearn for greater efficiency.
These pulleys spin on Grade 3, Abec 5 hybrid ceramic bearings.
Currently available in road seals only.
