Enduro Bearings choose the best materials and seals for their headset bearings, while headset manufacturers offer you bearings in Cr-Mo or Standard Steel for your carbon, steel or full mountain bike. It's the same thing as putting reconditioned tires on a rally car.

We do not offer low quality steering gear bearings. Instead, we start with chrome steel, type A/C black oxide finish, and then offer 440C stainless steel on top.

They are always designed with the largest possible balls and dual lip seals mounted in a micro groove for added protection against sweat and other types of dirt.

They're filled with 90% high pressure waterproof grease, so you never have to guess if there's grease on the inside.
