Rogue CB-4 38MM Camber Bar
Rogue CB-4 38MM Camber Bar
Product Description
The Rogue CB-4™ 38MM Camber Bar was developed in collaboration with Westside Barbell, and made its public debut as the “Double T” Bar at the 2022 Arnold Strongman Classic (nick-named in honor of the late Dr. Terry Todd). The goal with this design was to build a curved / bowed specialty bar suited not only to the world’s top powerlifters and Strongmen, but athletes of every size and ability level. To get there, we started with a series of different prototypes–of varying diameter, bend angle, and knurl pattern–and sent them all over to the least compromising focus group in the iron game: the athletes at the Westside Barbell Gym. Through their repeated testing and direct feedback, we were then able to determine which specs best delivered all of the key benefits we were looking for.

Rogue CB-4 38MM Camber Bar
The Rogue CB-4™ 38MM Camber Bar was developed in collaboration with Westside Barbell, and made its public debut as the “Double T” Bar at the 2022 Arnold Strongman Classic (nick-named in honor of the late Dr. Terry Todd). The goal with this design was to build a curved / bowed specialty bar suited not only to the world’s top powerlifters and Strongmen, but athletes of every size and ability level. To get there, we started with a series of different prototypes–of varying diameter, bend angle, and knurl pattern–and sent them all over to the least compromising focus group in the iron game: the athletes at the Westside Barbell Gym. Through their repeated testing and direct feedback, we were then able to determine which specs best delivered all of the key benefits we were looking for.
Design Intent:
- A bar that takes pressure off of the shoulders and elbows, allowing athletes with flexibility issues or injuries to continue to squat heavy.
- A bar that accommodates the size of the strongest competitive and at-home lifters, giving them room to place their hands wider apart than a standard barbell.
- A bar that allows athletes to increase their range of motion when benching while, again, keeping undue stress off of the shoulders and elbows.
- A bar that enables athletes to build strength with less weight . . . specifically, by providing the optimum drop between the center of the bar and the sleeves, the athlete is forced to keep the lower back tight in the squat, resulting in a stimulus greater than that of the same weight on a straight bar.
- A bar that does not bounce at high weights of 900 LBS or more, reducing safety risks.
The solution was the CB-4 Camber Bar, a 60LB, 38MM curved power bar with a 4.4” drop and a substantial 55” wide bend, giving athletes of every size the ability to find a point on the curve that works for them. In addition to allowing more hand placement flexibility, the extra 9” of distance between the sleeves also ensures that–on most racks– the cambered portion of the bar won’t flip down when unsupported.
The 95” shaft of the CB-4 is machined at our Columbus factory with our power bar knurl, then precision-bent by one of our local partners and finished with a Black Cerakote coating for excellent corrosion resistance and a firm grip. The rotating sleeves are friction welded and machined in-house and given our new proprietary matte black finish, which is the best in the industry for extending the vibrancy and longevity of the color. Once assembled, all bars are individually tested and assessed for quality before shipping out. This includes ensuring that each sleeve is straight, within an angle tolerance of +0.5 / -0.0 degrees.
*Please Note: The optional Proprietary Matte Black metal treatment process also hardens the steel, which can cause some additional friction with plates that have a chamfer.

Key Features of the CB-4 38MM Camber Bar
Put to the Test at the Arnold Classic
This bar made its public debut as the “Double T Bar” (in honor of Dr. Terry Todd) at the 2022 Arnold Strongman Classic. In the Maximum Squat event, it handled extremely heavy loads up to 966 LBS, proving it had no limitations even at the highest levels of competition.
Developed with Westside Barbell
Rogue worked with the team at Louie Simmons’ legendary Westside Barbell to test and refine the CB-4 Camber Bar, giving their athletes a wide range of different bar diameters and sleeve spacing in order to identify the specs that would best achieve our central goals: reducing stress on the shoulders and elbows; enabling greater flexibility in hand placement; improving safety on heavy lifts; and allowing athletes to build strength with less weight.
Greater Strength Gains, Less Weight
By providing the optimum drop between the center of the bar and the sleeves (4.4”), the curved design of the CB-4 Camber Bar forces the athlete to keep their lower back tight in the squat, resulting in a stimulus greater than that of the same weight on a straight bar.
All Local Construction
The CB-4 38MM Camber Bar is machined and assembled at the Rogue factory in Columbus, Ohio, with additional precision bending of the shaft provided by one of our local partners. We used our standard power bar knurl (with center knurl) for a firm grip, and the rotating sleeves are friction welded for a bond as strong as a single piece of steel. The 38mm diameter bar weighs 60 LBS unloaded and features 16” of loadable sleeve length with an angle tolerance of +0.5 / -0.0 degrees. All bars are backed by a Lifetime Warranty.*
Always Finish Strong
The bar’s shaft features a Black Cerakote finish; this is a ceramic-based coating first widely used in the firearm industry for its remarkable durability in thin applications. Few finishes offer better corrosion resistance over time. For the sleeves, we used our equally robust proprietary matte black finish, which greatly extends the longevity and vibrance of the color far beyond traditional barbell finishes.

Summary of Reviews
The product is a high-quality specialty barbell praised for its excellent knurling, solid construction, and ability to provide relief for the shoulders during exercises. Many users found the 38mm diameter comfortable and helpful for managing elbow and shoulder issues. However, some customers reported difficulties with loading and unloading plates due to the sleeves, as well as minor imperfections in the finish. A few reviewers also mentioned the bar's length may be an issue for those with limited space. Overall, the product is described as a well-designed and effective specialty bar, particularly well-suited for squats and lower body exercises.
