Product Details
Since 1996 White Industries has partnered with the folks at Enduro to ensure that the bearings we install in all our products are of the highest standards. Along the way Enduro has continually sought out better materials, seals, greases, tolerances and manufacturing techniques to stay on the cutting edge of bearing development and performance. These are the same Enduro angular contact 440c stainless steel bearings that come standard with our headsets.
Consult the information below for the bearing specs for your headset model. Bearing specs for specific headset models is also available on the respective headset model pages.
Specs
- Sold individually
- Headset bearings are ABEC 3 grade angular contact, made from 440c stainless steel and use a special Almagard 3752 grease.
- Bearings use either a 36 or 45 degree or inner angle, and a 45 degree outer angle
- 45 degree outer angle between the bearing and cup (or frame) keeps everything aligned and tight as well as allowing for easy bearing replacement
- Bearings are not press-fit into the cups. This is what makes them so easy to replace!
