Quick verdict
LiftEvidence editorial assessment
A 45 lb, 29 mm power bar with a 190,000 PSI shaft rated to 1,500 lb, an aggressive knurl and no bearings — the stiff, slow-spinning setup powerlifters want for squats, bench and deadlifts. The Cerakote shaft resists rust far better than bare or phosphate finishes. Grip feedback is mixed: some owners expected a sharper knurl.
