The X Training Equipment Elite Bearing Bar regularly outperforms bars that cost two or three times as much. We started with 215K PSI alloy steel, which is known for its unique ability to handle heavy lifts without permanently bending. Then we developed a medium knurl with dual markings that is firm yet comfortable. Next, we found the best performing needle bearings that gave us the least amount of friction for optimal spin. Lastly, we coated the bar from end to end with a hard chrome finish which has all the protective properties of standard chrome, but is not as slick and gives the bar a more natural feel.
