Information
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.
All of our headset bearings are ABEC 3 grade angular contact, made from 440c stainless steel and use a special Almagard 3752 grease. The bearings use either a 36 or 45 degree or inner angle, and a 45 degree outer angle. The 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 cups!).
