The KOGEL Bearing Advantage
Wheel bearings are among the fastest rotating parts on a bicycle. They are also under constant load and there are usually six of them, which means around twelve seals. For all these reasons it is worth upgrading from the stock bearings that came in your wheel set.

KOGEL ceramic bearing balls are smoother and rounder than any steel bearing because of their material properties. Silicon Nitride can be polished much smoother than steel. Also, it does not compress as much as steel, leaving the contact points with the bearing races very small and not squashed like a tennis ball under load. Compressing any material under load and trying to roll it will cause unnecessary drag and load.

With 2 bearings in the front, 2 in the rear and 2 in the freehub, it is worth considering what you want from your seals. The KOGEL Bearings Road seals are built to create the lowest friction we can get out of a sealed bearing. The Cross seals are built to have the best protection against the elements. Pick whichever best suits your riding style.

Choosing the right bearings

Now that you know why a ceramic wheel bearing upgrade is important, we get to the hard part: which bearings are in your wheels? Many manufacturers are notoriously secretive with this information. They will change bearing sizes from one model to the other, or even mid-season in a set. For this reason, we recommend you visit one of our KOGEL dealers here and have them assist you!
