Double Black Diamond Power Bar

Type: Bars
SKU: BB-5320

Raising the bar. These barbells were over 10 years in the making – the fusion of customer insights, rigorous testing, thousands of reps by different types of athletes, and our decades of experience in both lifting and designing quality, innovative gym equipment. That’s how we know these will be the best barbells you’ll ever put your hands on.

The Double Black Diamond Power Bar is REP’s top-tier powerlifting barbell with very aggressive knurling. REP was founded in Colorado, and the Double Black Diamond name references the steepest and hardest runs on the slopes. This 20kg (44.1lb) barbell features deep, mountain-style knurling to provide maximum grip for heavy bench presses and deadlifts, and center knurling to keep the barbell in place during back squats.

It also has IPF-standard knurl markings to help you get into proper position for your lifts, and it features smooth sleeves for easy loading and unloading of the plates. This power bar has a stiff 29mm diameter, which complies with International Powerlifting Federation standards. Bronze bushings allow for consistent rotation, while ensuring incredible strength and stiffness to withstand heavy loads. In fact, this bar can handle up to 1,500lbs. The Double Black Diamond comes in six styles: fully stainless steel; a stainless-steel shaft with hard chrome sleeves; or a black, blue, green, or red Cerakote shaft with Duracoat™ sleeves. Duracoat™ is a chemical process that hardens the outside of the steel, making it more wear resistant than other finishes while also adding a high degree of corrosion resistance. The bar is topped off with premium metal endcaps with unique designs. This is a powerlifting barbell that stands out from the rest. For a powerlifting bar with a still aggressive knurling, but less so than this bar, check out the regular Black Diamond version of this barbell.
