Mondraker Raze Carbon 2022+ (inc 2026) Headset Bearing Kit (IS52 icr/ZS56)(with or without Blocklock on lower)
Please note the lower bearing on this headset has been pressed into the cup (it was designed to be a non-serviceable part); therefore, care has to be taken in removing this bearing from the cup to replace it. If you notice any damage to the cup after removing, then your lower headset should be replaced. We stock a Cane Creek Lower Headset that is an ideal replacement for this. You can find it here.
This Headset Bearing Kit fits the above Mondraker using the Acros IS52(icr)/ZS56 headset.
You will receive two headset bearings of two different sizes in your choice of the following:-
Enduro Stainless Steel Kit
Not all stainless steel is created equal. Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all the standard 440-series stainless alloys with high carbon content. As expected, it is also the most expensive of the 440 series alloys and requires special heat treatment and cryogenic treatment to achieve its superior mechanical properties. Though it is slightly softer than our standard 52100 chromium steel used in most of our bearings, stainless steel is an excellent alternative for use in wet conditions or where sweat and spilled sports drinks can be a problem. Enduro Bearings also uses LLB-type seals and Almagard 3752 grease in these bearings to additionally waterproof against the elements. Enduro 440C stainless headset bearings are the same bearings found in many popular headset brands with a lifetime warranty.
The Enduro line of angular-contact headset bearings starts with Black Oxide treated Chromium Steel races and then steps up to full 440C stainless steel. They are always engineered with the largest balls possible, feature dual-lip seals riding in a micro-groove (labyrinth), and are filled 90% with high-pressure waterproof grease for the ultimate protection against sweat and the elements. Enduro Angular Contact (A/C) bearings are designed so all balls are evenly engaged to spread the force over a larger surface area, minimizing wear and maximizing life.
