💡 What advantages do ceramic hybrid bearings offer over full steel setups?

Upgrading to a hybrid design proves highly handy when you want to drop rotational weight while keeping massive load capacity.
- Silicon nitride ceramic spheres resist heat buildup and run smoother than traditional steel components under heavy pedaling strokes.
- Grease sealed grooves trap dust and moisture out while locking in factory lubricant for long service intervals.
- The tight tolerance fit handles steep climbs and hard impacts without expanding or developing unwanted play.
