Introduction

Enduro Bearings don’t mess around with inexpensive headset bearings, it’s simply not worth it. While many headset makers will offer you Cr-Mo or standard steel headsets for your carbon road bike, steel cross bike, or full suspension mountain bike, Enduro feels that’s like putting bias ply tires on a rally car. Enduro doesn’t offer the entry level for headset bearings. Instead, they begin with chromium steel, Black Oxide finish A/C type and then offer full 440C stainless steel at the top. They are always engineered with the largest balls possible and dual lip seals riding in a microgroove for ultimate protection against sweat and the elements. They are filled 90% with high-pressure waterproof grease, so you don’t have to ever guess if there is grease inside. Watch for more headset related components and even larger selection of sizes in 2015 from Enduro Bearings.

• LLB – Is a double lip seal making light contact, and also rides in a groove making a labyrinth seal (reducing friction for less rolling resistance whilst maintaining a good seal, preventing contaminating particles entering the raceways).
• Black Oxide Raceways – which get an additional Magnetite treatment for hardness, rust resistance and greater reliability.
• Outer Chamfer 36 degrees, Inner chamfer 45 degrees.

Grade 5 Chromium Steel Balls:

• High precision balls are within a 5/1,000,000 round. These are a military level specification, used for precision equipment. R-64 hardness, of the highest grade.

52100 High Carbon Chromium Alloy Races:

• Vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-3 precision and noiseless movement.
