The Vulcan Black 15 kg Bearing Bar for women 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 an equally impressive amount of whip for this price range. This Bar performs excellently for CrossFit without the higher expense of the Vulcan 15 kg Women'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 other 20 kg and 15 kg Bushing bars that sell at a higher cost. We use black oxide finish for this bar which is not as durable or maintenance free as hard chrome finish on our 15 kg Professional Olympic bearing bar but definitely will last well if maintained and lowers the cost significantly on this piece. This is the ultimate bar for full use in CrossFit® gym, as well as garage gym. The depth and pattern of the knurling on the Vulcan Bar is superbly crafted. This CrossFit weightlifting Bar can be used for either CrossFit® workouts, power lifting, 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 wiping down with 2 in 1 oil to prevent corrosion.
