TORCH - RD - Ceramic Full Bearing Kit for Center Lock - XD-15
XD-15 ceramic bearings are unique in their corrosion resistance and strength.
They 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.
Our XD-15 bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls in a proprietary process that results in the ultimate high performance bearing setup.
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.
Made in the USA.
Precision machined and ground to ABEC-5 tolerances at our facility in Gilroy, California.
Voted “Hands down the best bottom bracket we have ever tested” from Bike Radar.
These bearings spin with the very least resistance of anything we have developed to date featuring oversized Grade 3 Silicon Nitride balls. On top of this, they will be spinning with the same ease one year or even two years from now, with longer intervals between servicing. No one else in the bicycle industry offers this combination of speed and durability: XD-15 bearings for wheels, bottom brackets, and drive train.
