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 multiple rounds of heat treatment and cryogenic treatments to achieve its superior mechanical properties. Though stainless steel has 20% less load capacity and 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, if you wash your bike often, or where sweat can be a problem. Enduro Bearings also uses LLB type seals and CRC Marine Grease in these bearings to additionally water proof against the elements. All Enduro stainless headset bearings carry a limited lifetime warranty.

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.

Appearances Can Be Deceiving. Perfect Size
Color: Gold Triple Huggie
When I opened the package I was shocked at how tiny these appeared and my immediate thought was to return them without even trying them on. That would have been a mistake. I did order them because they were a smaller version of this look and I wanted them to look elegant and sophisticated rather than making a bigger statement. Well, that is exactly what I got. The gold color is very nice and once I decided to put one on, and got it through my chubby earlobe, it was absolutely perfect and the look I was going for. I have larger ear lobes and they still hang down enough for some movement rather than just cupping my earlobe like a true cuff. If you want this style with a more minimalist and elegant look, these are your earrings. I highly recommend them and be sure to try them on before you make a decision.

Good everyday earning
Color: Gold Triple Huggie
Super cute earrings. They are my go to earrings. I wear them everyday. Easy on and off. Not post earrings, so no looking for the backs that got dropped.
