Enduro Standard Abec 5 are premium replacement bearings. These are great for hubs, pedals, and bottom brackets.

ABEC 5 bearings feature:

• Grade 5 Chromium Steel Balls.
• In spec to 5/1,000,000″ (military grade)
• 52100 High Carbon Chromium Alloy Races .

 What's the difference between ABEC 3 and ABEC 5?

ABEC is an acronym for a committee that sets standards for bearings. Higher numbers mean higher tolerances (and price). For example, ABEC 3 balls are in tolerance to 10/1.000.000" vs. 5/1.000.000" in the ABEC5.

How does this affect me?

Higher tolerance bearings are smoother and faster. With precision, the balls will support the bearing better and increase life expectancy.

To find the correct bearing, please check your owner's manual. These are premium bearings that are among the longest lasting available, however bearing life is dependent on factors such as weather, maintenance, and installation. Please use correct installation methods and follow your component's torque specifications. Failure to do so will result in premature bearing wear.
