Key Features & Specifications
Shaft Diameter: 28.5mm (Multipurpose standard).
Weight: 20KG (44 lbs).
Tensile Strength: 190,000 PSI.
Shaft Finish: Black Zinc—provides oxidation resistance while being thin enough to preserve the tactile feel of the knurl.
Sleeve Finish: Bright Zinc—adds oxidation resistance and a classic look.
Knurling: Dual knurl marks (Olympic and Powerlifting) with a "middle of the road" feel—firm enough for heavy pulls but not abrasive for high-rep sets.
Center Knurl: No. This prevents skin irritation on the neck during movements like cleans and front squats.
Rotation System: Precision-machined bronze bushings for a smooth, stable, and 2X quieter spin.
Durability Rating: F8-R (Treated with Rogue Work Hardening for increased fatigue resistance).
Origin: Made in the USA from US steel.
Enhanced Performance Benefits
Stricter Tolerances: Precision-machined bronze bushings fit tighter around the shaft, reducing axial and radial float. This results in a more solid, "connected" feel during lifts and significant noise reduction.
Low Profile Sleeves: Machined with a new low-profile design that makes loading and unloading plates smoother and faster.
Friction Welding: The collars of the sleeves are friction-welded, creating the strongest sleeves in the industry—as strong as if machined from a single piece of steel.
Maintenance and Care
Black Zinc is a durable finish, but it will require simple maintenance to prevent rust, especially in humid or garage gym environments.
Regular Brushing: Use a nylon bristle brush to remove chalk, sweat, and skin from the knurling after use.
Cleaning: For deep cleaning or to treat stubborn debris, apply a light coat of 3-in-1 oil to the knurl, brush it in, and wipe dry with a clean cloth.
Lubrication: The bronze bushings are self-lubricating, but a drop of 3-in-1 oil can be added to the sleeve-to-shaft interface if the rotation begins to feel restricted.
Preserve the Finish: Metal-to-metal contact (racking on steel J-cups or using iron plates) will cause the zinc to wear. Using plastic-lined J-cups is recommended to preserve the aesthetic.
Warranty Information
The Ohio Bar is backed by a Lifetime Warranty against construction defects and bending.
Coverage: Covers the original purchaser against material and workmanship defects.
Exclusions: Does not cover normal "wear and tear" on the finish (scratches/chips), or damage caused by negligence (e.g., dropping the bar on a bench, spotter arms, or safety pins).
Frequently Asked Questions (FAQ)
Q: Is the Ohio Bar a "Power Bar"? A: No. The Ohio Bar is a multipurpose bar with a 28.5mm shaft and natural "whip." For a stiffer bar designed specifically for the Big Three lifts, see the Ohio Power Bar.
Q: Why choose Black Zinc over Cerakote or Stainless Steel? A: Black Zinc is an industry-standard finish that offers good rust protection and a classic feel at a more affordable price point than Cerakote or Stainless Steel.
Q: Can I rack this bar in a standard power rack? A: Yes. The 52" shaft length between sleeves allows it to be racked on all standard-width power racks, squat stands, and rigs.
Q: What is the F-Rating? A: The F-Rating (F8-R) is a measured representation of the barbell's fatigue resistance based on functional testing (overhead drops). This bar is rated to last 16 years in a high-volume CrossFit gym and a lifetime in a home gym.
