Barbells that bend or rust are just expensive scrap metal.
Why Not Just Buy the Cheap One?
Cheap $120 barbells from cap or fitness depot have wimpy steel that bends with heavy deadlifts, knurling that wears off in a month, and bushings that grind. The Rogue Ohio Bar is made from 190,000 PSI tensile strength steel, has dual snap rings for consistency, and comes with a lifetime warranty against bending.
The Buy-Once Math
A cheap bar that bends after 2 years costs $120—and then you need to buy another (plus risk injury when it snaps). The Rogue bar costs $295 but outlasts your gym membership, maintains resale value (~$150), and won't let you down at 500 lbs. One bar for life beats a graveyard of twisted metal.
