Wheel bearings are among the fastest rotating parts on a bicycle. They are also under constant load and there are six of them, which means twelve seals. For all these reasons it is worth upgrading from the stock bearings that came in your wheel set.
The Kogel Bearing Advantage
Kogel ceramic bearing balls are smoother and rounder than any steel bearing because of its 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.
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, it is very tough for us to list every possible combination on our website.
To make things easy, we have made a flat fee pricing for a set of four (front and rear hub, but without freehub) or six (a complete wheelset including the freehub).
Get Help Finding The Right Wheel Bearings
Before you order, send us a message via firstname.lastname@example.org or the use the form at the bottom of your screen. Be sure to include details about your wheelset and bicycle frame.
Once we know the make, model and year of your wheels, there is a good chance we know which bearings to send. Sometimes we will ask you to open the wheels to have a closer look at the bearing numbers or sizes.
