The Vulcan Black 20 kg Bearing Barbell for men combines the latest technology in bearing bar design with extreme durability, performance within an affordable price. This bar spins just as well as the higher priced professional version with a decent amount of whip for a bearing bar in this price range. This Bar performs excellently for CrossFit® training without the higher expense of the Vulcan 20 kg Men's Professional Olympic Bearing Bar. To reduce the bottom line cost of this barbell, tensile strength is lowered to 191,000 psi, which is still considerably more tensile strength than many 20 kg and 15 kg Bushing bars that sell at a higher cost. We use Black Zinc coating for this bar. Black Zinc is not as durable as the hard chrome finish on our Professional Olympic bearing bar but definitely will last well if maintained. Black Zinc is a better coating that black oxide and requires less maintenance. This is the ultimate bar for full use in CrossFit® gym, as well as garage gym. The depth and pattern of the knurling on this Vulcan Bar is superbly crafted. This Oympic weightlifting Bar can be used for either CrossFit® workouts, Olympic Weightlifting, or conventional weight training exercises. This advanced multi-use bar utilizes 4 quality needle bearings in each sleeve. This bar will never become loose or dislodge and never requires maintenance other than an occasional oiling.
