Product Details
Since 1996 White Industries has partnered with the folks at Enduro to ensure that the bearings we install in all our products are of the highest standards. Along the way Enduro has continually sought out better materials, seals, greases, tolerances and manufacturing techniques to stay on the cutting edge of bearing development and performance. Our hubs come standard with Enduro high-carbon chromium steel bearings which have the best price/performance ratio, but if you are seeking the absolute pinnacle of bearing performance, we also offer Enduro XD15’s which features ceramic balls rotating in aerospace developed, nitrogen-infused, super-stainless-steel bearing races and come with a limited lifetime warranty.
