Description
After logging some serious miles on your ride, you may notice your bearings not performing as they once did. This is normal and to be expected as a bearing is a part that sees a lot of wear and tear. No need to worry, though, as we’ve got you covered! We offer a bearing replacement kit for every hub that we sell so that you can make your wheels spin like new again. In our premium hubs we use only the highest quality of bearings from Enduro. They are made to very exacting standards and are built to perform in even the most demanding situations. We also offer ceramic bearings from Enduro that reduce rolling resistance and last even longer than their steel versions if properly maintained!
From Enduro’s Website:
“Grade 5 Chromium Steel Balls
High precision balls are within 5/1,000,000″ round. These are military level specification, used for precision equipment. R-64 hardness, of the highest grade.
52100 High Carbon Chromium Alloy Races
Vacuum de-gassing process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-5 precision and noiseless movement.
Graphite/Nylon Ball Retainers
Nylon with graphite retainers are virtually frictionless while providing constant lubrication.
The ABEC 5 Standard
To meet the ABEC-5 standard, bearing design must pass all tests, which include noise testing at high RPM, extremely close tolerances for I.D. and O.D., roundness of ball, trueness of the races and micro surface finishes of balls and races.
C-3 Clearance
This specification describes the internal clearance between the bearing and its race. For example, in a 10-18 I.D. bearing, our standard is 11-21 micrometers whereas others use 11-25 micrometers.
All across the board, our bearings have higher standards of tolerance to ensure superior performance.”

NOTE: Riding conditions drastically affect bearing life. Wet, muddy, and dusty conditions will greatly reduce the longevity of any bearing and proper maintenance is necessary to make them last as long as possible. This includes cleaning and repacking the grease in the bearings after they are subjected to less than ideal conditions for an extended period of time.

How do I know if my bearings need to be replaced? There are a few factors to consider when it comes to evaluating the condition of your bearings. The amount of ride time you have on them and the conditions in which they were ridden both affect the expected life of the bearing and can vary significantly. If the bearings begin to feel excessively rough or notchy or the inner race begins to show a high degree of play then it may be time to swap them out.
