XD-15 ceramic bearings use a different material than any other bearing on the market and is exclusive only to Enduro bearings. 

XD-15 ceramic bearings utilize an advanced stainless alloy that is unique in it’s corrosion resistance and strength.

XD-15 is a very special nitrogen infused steel material that will not rust or corrode. Even running in salt water or any caustic nutrition drink you can spill, it will not be degraded or affected. Even dirt or sand inside will not wear it out; it will simply polish the races smoother.

The manufacturing process to produce this alloy involves re-melting a very high grade of martensitic stainless steel from the end of an electrode. This occurs in a highly-controlled re-melt chamber while introducing nitrogen gas, producing a homogenous steel, free from course carbides and giving ultimate fatigue resistance.

Enduro XD-15 bearings combine corrosion-proof, cryogenically treated nitrogen steel with Silicon Nitride Grade 3 ceramic balls in a proprietary process that results in the ultimate high performance bearing setup. The Grade 3 Ceramic balls are made from pure Silicon Nitride with extreme high density from uniform compaction (3.25 g/cm3).  The micro-structural development of this material during manufacture is second to none. These high precision Grade 3, SI3N4 pure ceramic balls are 3/1,000,000” from exactly round in sphericity. They are 60% lighter in weight, and 7 times harder than steel.

When compared to other ceramic-hybrid bearings on the market that claim speed and power advantages on day one, Enduro XD-15 bearings not only provide the same initial advantages on day one, but will get even faster and smoother with time and use, while the other ceramic-hybrid options will only get slower.

Enduro XD-15  bearings come with a lifetime limited warranty to the original owner. You will not only save watts, you will also save maintenance time. XD-15 is the pinnacle in bicycle bearing technology.
