The Enduro line of headset bearings consists of two basic performance levels that are a substantial step up from standard bike industry specifications. Enduro "entry-level" headset bearings feature premium materials like Black-Oxide treated races and carry a two year warranty, while our premium 440C stainless headset bearings carry a full lifetime warranty. 

All Enduro bearings are always engineered with the largest balls possible and feature dual lip labyrinth seals for maximum protection against sweat and the elements and to contain the 90% high pressure water proof grease, keeping everything running smoothly for the duration. The Angular Contact (A/C) design of Enduro headset bearings allow all balls in the bearing to engage the load, spreading the force over a larger surface area minimizing any possibility of premature wear and greatly extending bearing life.
