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:

1. A bar that takes pressure off of the shoulders and elbows, allowing athletes with flexibility issues or injuries to continue to squat heavy. 
2. 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.
3. A bar that allows athletes to increase their range of motion when benching while, again, keeping undue stress off of the shoulders and elbows. 
4. 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. 
5. 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.
