Rogue 28MM IWF Olympic Weightlifting Bar w/ Center Knurl - Bright Zinc
Combining a 215K PSI steel shaft with quality needle bearings, friction-welded sleeves, and a full but non-abrasive knurl pattern, this IWF Approved version of our Rogue Olympic Weightlifting Bar ranks among the best in the industry for feel, durability, and performance.
Each 20KG bar is machined and assembled in Columbus, OH, and includes a center knurl for added “stick” along with official IWF branding on both the shaft and endcaps. In the strength world, approval from the IWF (International Weightlifting Federation) is equivalent to a restaurant getting its Michelin stars, so achieving that recognition for this barbell is a true point of pride and a testament to the level of precision that goes into its design and construction.
We currently offer the IWF Oly WL Bar in a Bright Zinc finish. Other variations on this bearing bar include:
- Oly WL Bar - Bright Zinc - No Center Knurl
- Cerakote Oly WL Bar - No Center Knurl
- 15KG Women’s Oly WL Bar - No Center Knurl
*The variations above may still be pending IWF approval.

KEY FEATURES OF THE IWF APPROVED ROGUE OLYMPIC WEIGHTLIFTING BAR:
215,000 PSI Tensile Strength
Our Men’s Olympic Bar is made exclusively from high-grade steel, producing a shaft with a minimum tensile strength of 215,000 PSI. Each shaft is ground and polished prior to machining (to ensure a smooth finish), and individually tested and straightened to within 0.015” (0.38mm). The goal is to create just the right amount of “whip” or “flex” needed for competitive Olympic lifting. A Bright Zinc finish completes the look and offers solid oxidation resistance.
Friction Welded Sleeves + Needle Bearings
Using a process from the worlds of aviation and automotive manufacturing, the sleeves on the Rogue Olympic Weightlifting Bar are friction welded—creating a superior, forged-quality bond. This method is more precise than most joining techniques and helps prevent any changes in the integrity of the sleeve. Combined with 10 sets of top-quality needle bearings, the result is a barbell with a smooth, consistent, quieter spin.
Precision Machining
Every Olympic Bar is machined in Columbus, Ohio, on new Haas machines that are built in the USA. For the Olympic knurl marks and center knurl, we experimented with several knurling patterns before choosing the full but minimally aggressive texture that top weightlifters responded to best. Rather than relying on visibility alone, each bar is manually tested to ensure the actual “feel” is up to Rogue standards.
A New Addition to Your Rogue Arsenal
As the leading manufacturer of strength and conditioning equipment, Rogue produces a wide range of Olympic bearing bars and related gear. Along with the standard Men’s Oly WL Bar, we also offer the Cerakote Oly WL Bar, and the Women’s 25MM Oly Bar. You can also combine your bar with quality plates, collars, and secure storage systems .
IWF Certified
This specific version of the Rogue Olympic Weightlifting Bar has received approval from the International Weightlifting Federation (IWF) for competitive use; a statement on its precision adherence to the organization’s high standards. Each bar is fitted with a machined stainless steel end cap with IWF branding to note this certification. An official IWF sticker is also included on the bar’s shaft.
F SCALE™
The F Scale™ is a durability scale for barbells based on functional testing at stresses similar to what barbells experience when being dropped from overhead. Bars that have been treated with Rogue Work Hardening (RWH™) are designated by having an R in their F Rating™. For more information on F Scale™ click here.
OXIDATION RATE
The resistance of a barbell to oxidation depends on the type of steel and the coating. Barbells at the lower end of the spectrum will require more care and maintenance to preserve their appearance than barbells at the upper end of the spectrum.
*Warranty against bending does not cover any bar which has been damaged due to negligent or faulty use, alteration, maintenance, storage or handling by the user. Negligent or faulty use includes abusive dropping of the bar (i.e., dropping the bar on a box, bench, spotter arms or pins in a power rack, excessive dropping with insufficient or damaged bumpers, or excessive dropping with iron plates, and similar usage). Any specific issues regarding a Rogue product with which a customer is not satisfied will be reviewed on a case-by-case basis. We have found that most problems with bars we replace are related to abusive use rather than manufacturing or materials issues.
