Overview
The Rogue KG Competition Collars are precision-engineered, CNC-machined barbell collars designed for high-stakes competition and elite training environments. Approved for official use by both the International Weightlifting Federation (IWF) and the International Powerlifting Federation (IPF), these collars set the industry standard for stability and strength. The 2.0 version has been upgraded from cast steel to machined billet steel, offering a more robust body and superior corrosion resistance.

Key Features & Specifications
Certifications: IWF and IPF Approved for competitive use.
Construction: Main body machined from high-grade Billet Steel with a cast star locking ring.
Finish: Durable Hard Chrome finish for maximum abrasion and rust resistance.
Weight: 2.5 KG each (5 KG total per pair).
Weight Tolerance: Strict calibration of -0 / +10 grams per collar.
Width: Compact design (Approx. 3" to 3.625") to maximize loadable sleeve space.
Locking Mechanism: Features an advanced ball-lever handle and a star locking ring for secondary security.
Performance Benefits
Precision Calibration: These collars are manufactured to exacting weight standards, ensuring that "record-setting" lifts are accurate to the gram.
Vise-Like Grip: The internal arched steel sleeve compresses uniformly around the barbell, providing a secure hold that prevents plate rattle even during high-impact Olympic drops.
Safe for Barbell Finishes: The compression mechanism is designed to tighten without marring or scratching the surface of high-end barbell sleeves (e.g., Stainless Steel or Cerakote).
Speed and Efficiency: The combination of the ball-lever and the rotating star ring allows for quick weight adjustments, essential for the fast-paced nature of lifting competitions.
Attachment Instructions
Slide on the Bar: Place the collar onto the barbell sleeve with the cast star locking ring facing the weight plates.
Tighten the Lever: Rotate the ball lever handle. This compresses the internal steel sleeve to lock the collar onto the bar.
Lock the Plates: Once the lever is tight, rotate the star locking ring manually until it is flush and snug against the plates to eliminate all movement and noise.
Maintenance and Care
Cleaning: Use a microfiber cloth to wipe away fingerprints and chalk from the hard chrome finish.
Lubrication: Periodically apply a small drop of dry lubricant to the ball-lever pivot point and the star ring threads to ensure smooth mechanical operation.
Storage: Store in a dry environment. While hard chrome is highly resistant to rust, keeping them off damp gym floors when not in use will extend the life of the internal components.
