Overview
The Rogue CB-4 38MM Camber Bar is a specialty "Buffalo-style" powerlifting bar designed to build strength while reducing safety risks and joint strain. Developed in collaboration with the legendary athletes at Westside Barbell, it features a unique curved shaft that provides a 4.4” drop. This curvature forces the lifter to maintain a tighter lower back during squats and offers an increased range of motion during bench pressing. Its oversized 38MM diameter provides a massive surface area for maximum comfort on the back or in the hands.

Performance Benefits
Shoulder and Elbow Relief: The 4.4” drop places the hands lower than a straight bar, significantly reducing stress on the shoulders and elbows during squats—ideal for athletes with mobility issues.
Greater Training Stimulus: The cambered design shifts the center of gravity, forcing the lifter to engage the core and posterior chain more aggressively to stay upright.
Increased Range of Motion: During bench press, the curve allows the bar to travel further toward the chest before touching, recruiting more muscle fibers.
No "Bounce" at High Loads: Tested at the Arnold Strongman Classic with loads exceeding 960 LBS, the CB-4 is engineered to remain stable and avoid the dangerous oscillating "whip" common in thinner specialty bars.
Anti-Flip Design: The extra 9” of spacing between the sleeves helps ensure the cambered portion of the bar won't flip down when placed in most racks.
Maintenance and Care
Proper maintenance is required to preserve the Cerakote finish and ensure the sleeves continue to spin smoothly.
Regular Brushing: Use a synthetic (nylon) bristle brush to clear chalk and debris from the knurling after use. Important: NEVER use a steel brush on a Cerakote shaft, as it will scratch and damage the finish.
Cleaning: Periodically apply a light coat of 3-in-1 oil to the knurl, brush it in, and wipe dry with a clean cloth.
Bushing Care: If sleeve rotation feels restricted, a drop of 3-in-1 oil can be added to the sleeve-to-shaft interface.
Racking: Use J-cups with plastic or rubber liners to minimize wear on the Cerakote finish.
Warranty Information

Coverage: Applies to the original purchaser.
Exclusions: Does not cover normal finish wear or damage caused by negligence (e.g., dropping the bar on safety pins, boxes, or benches).
Frequently Asked Questions (FAQ)
Q: Will this fit on my standard power rack? A: Yes. While it has a longer total length and wider sleeves, the internal spacing is designed to be compatible with standard Rogue power racks and squat stands.
Q: Is the 38mm shaft too thick for benching? A: Most users find the 38mm diameter actually reduces hand and wrist pressure during pressing movements, though it may take a few sessions to adjust to the thicker grip.
Q: How does this compare to the Kabuki Strength Duffalo Bar? A: The CB-4 is thicker (38mm vs 32mm) and heavier (60lb vs 55lb). Many lifters prefer the CB-4 for the added comfort on the back during very heavy squats.
Q: Does it have knurl marks? A: Yes, it features standard powerlifting knurl marks to ensure consistent hand placement.
