REP Health Double Black Diamond Energy Bar In-Depth Assessment
Whereas we’ve beloved lifting with the Double Black Diamond Energy Bar, we understand that it will not be the best barbell for everybody. As talked about, the aggressive knurling could not swimsuit all types of lifting, and it’s not the most affordable energy bar obtainable. Relying on which end you get, it will not be utterly immune to rust or corrosion. However its excessive tensile energy means it might deal with tremendous heavy hundreds, and we predict it’s nonetheless a great worth contemplating its high-quality development and the way properly it performs for powerlifting coaching.
Value and Worth
The REP Health Double Black Diamond Barbell prices round $330 for the Cerakote choices, round $400 for the chrome steel and onerous chrome mannequin, and round $450 for the all-stainless metal model. It’s not too far off in value from the Rogue Ohio Energy Bar, which prices wherever from about $275 to about $415, relying on the end. Nevertheless, the Double Black Diamond bar is costlier than a solid budget barbell just like the Bells of Metal Barenaked Powerlifting Bar 2.0, which prices round $220.
That mentioned, REP Health affords free transport on all orders as of this writing. Contemplating that transport a barbell can price $25 or extra, the Double Black Diamond Bar could be a cost-efficient choice. Plus, with the sturdiness and glorious efficiency high quality it affords, we predict it’s an honest worth. We rated it 4.5 out of 5 stars for the worth.
Supply
I’ve purchased shut to 2 dozen items of house health club tools through the years and have additionally obtained complimentary gadgets resulting from my job as a health author. Most merchandise arrived completely packaged with none injury. Nevertheless, I’ve obtained two barbells whose packaging was broken upon supply. The bars had knicks and chips on the sleeves and shaft earlier than I even had an opportunity to make use of them.
I used to be pleased to listen to from our product testers that the supply of the Double Black Diamond barbell to our warehouse in Springfield, MO, went rather more easily. The barbell arrived in a cardboard tube with plastic finish caps that had remained intact throughout transport. The bar was additionally wrapped in foam and plastic to additional shield it from dings and scratches. We scored the supply course of 5 out of 5 stars.
Development, Supplies, and Coating
The Double Black Diamond Bar has a 29-millimeter shaft. This diameter is frequent in energy bars. Some, just like the Authentic Texas Energy Bar, have a 28.5-millimeter diameter. However in line with our product testers, 29 millimeters is the gold customary.
When ordering the Double Black Diamond Bar, you may select from three finishes: Cerakote (which is available in black, blue, inexperienced, or purple shade choices), chrome steel with chrome sleeves, or chrome steel with chrome steel sleeves. The Cerakote bars have Duracoat sleeves, which makes them more durable, extra corrosion-resistant, and fewer vulnerable to scratches and scuff marks from plate inserts.
No matter which end you select, you’ll get a bar with clean sleeves. I usually want barbells with ribbed sleeves as a result of I don’t use collars typically, and the ribbing helps preserve my weight plates in place. However once I educated with the Double Black Diamond Bar at our testing facility in Springfield, MO, I did admire how simple it was to slip plates on and off it. I additionally beloved how the top was beveled. The beveling made loading plates a breeze as a result of I didn’t should completely align the plate inserts with the top of the sleeve.
One factor I like concerning the Double Black Diamond Bar is the endcap design. The black endcap boasts raised silver lettering with the REP title and a double diamond define. It’s a small however distinctive contact that offers the barbell a high-end aesthetic. Equally, REP additionally added etching with its emblem and the bar’s title to the within of the collars. These traits could not appear to be a lot, however the high quality craftsmanship and a spotlight to element assist this bar stand out from its opponents.

All in all, this barbell will get 4 out of 5 stars for its development high quality.

Knurling
As this can be a energy bar, the Double Black Diamond Bar options powerlifting knurl marks as specified by the IPF. This implies it has single knurl rings and a small space of heart knurling. The knurl rings act as a reference level for the place to put your arms when bench urgent, whereas the middle knurl helps preserve the barbell in your again for again squats.
The knurling itself may be very aggressive. It’s a mountain-style knurling, which means it has a diamond-shaped sample with sharp, pointy peaks. Mountain knurling is frequent in energy bars as a result of it affords a superior grip for deadlifts. Nevertheless, energy bars with mountain knurling aren’t essentially the most snug to carry with, particularly for brand spanking new lifters, due to how aggressively they dig into the arms.

Alternatively, when you’re already used to lifting weights and have calluses constructed up in your palms, the knurling on the Double Black Diamond Bar could not trouble you as a lot. I’ve calluses on my arms from years of lifting weights and doing pull-up bar workouts in CrossFit WODs. Once I educated with the Double Black Diamond Bar, I undoubtedly seen the stickiness and grippiness of the knurling, however I wasn’t in a ton of discomfort.
As well as, REP makes use of increased enamel per inch (TPI, the variety of seen enamel per inch on the barbell) than different firms use on their energy bars. The mountain sample can also be much less pointy than what you’d discover on different energy bars. Primarily, you get a stable grip however don’t have to fret about tearing your pores and skin throughout each deadlift exercise. For these causes, we rated the knurling 4.5 out of 5 stars.
Tensile Energy
Tensile energy refers to how a lot weight a barbell can maintain earlier than it fractures. It’s measured in kilos per sq. inch (PSI). A excessive tensile energy is essential in an influence bar, particularly for lifters who can squat, bench press, and deadlift lots of of kilos. Usually, the upper the tensile energy, the extra abuse a barbell can deal with.
REP’s Double Black Diamond Bar has a tensile energy of 200,000 PSI. Different barbells we’ve examined and reviewed have increased tensile strengths. As an illustration, the Rogue Ohio Energy Bar has a 205,000 PSI tensile energy. Alternatively, the tensile energy of the Double Black Diamond Bar is increased than extra economical barbells, just like the Efficiency Sequence Energy Bar from Titan Health. Titan’s energy bar solely has a tensile energy of 165,000 PSI.
For these causes, we rated the Double Black Diamond Bar 4.5 out of 5 stars for its tensile energy.
Rotation System
The rotation system refers back to the mechanism a barbell makes use of for its sleeve rotation. Some barbells use bearings to rotate their sleeves, and others use bushings. Bushings are extra frequent in powerlifting bars as a result of they don’t spin as shortly or easily. For slower, extra grindy lifts just like the squat, bench press, and deadlift, slower rotation is useful as a result of the barbell will really feel extra steady.
The Double Black Diamond Bar makes use of bronze bushings. The bushings provide some spin, but it surely’s not as important as what you’d discover on an Olympic weightlifting bar, like REP’s Alpine Weightlifting Bar. However since a low quantity of spin is strictly what we’d hope for in an influence bar, we scored the rotation system 4 out of 5 stars.

Versatility
As talked about, the Double Black Diamond bar is an influence bar. It’s not a multi-purpose bar like REP’s Colorado bar or Rogue’s common Ohio bar. Whereas it’s nice for powerlifting, it wouldn’t be appropriate for the dynamic actions you’d discover in CrossFit. The aggressive knurling received’t be snug in your palms throughout actions the place the barbell could rotate in your arms continuously, like thrusters or push presses.
Additionally, as a result of the barbell solely has single IPF knurl marks and doesn’t conform to Worldwide Weightlifting Federation (IWF requirements), it’s not ideally suited for Olympic weightlifting (snatches and clear and jerks). We solely gave it 3 out of 5 stars for versatility since we don’t advocate utilizing it for something aside from powerlifting. A high-quality, all-purpose bar with medium knurling and twin knurl marks could also be extra appropriate for energy sports activities that make the most of extra explosive barbell actions.
Sturdiness
We’ve solely had the all-stainless metal Double Black Diamond Bar at our testing heart for a few months. Up to now, it has held up properly. However in our expertise, REP’s chrome steel bars are likely to rust shortly. We’ll should let extra time move to see if the Double Black Diamond Bar begins to rust or if it continues to look pristine.
Even so, we rated the bar 5 out of 5 stars for sturdiness. As talked about, the barbell can also be obtainable with a Cerakote end. Different Cerakote barbells we’ve examined, like Rogue’s Cerakote Barbell, have lasted for greater than six months with out rusting. That is regardless of day by day use and being saved in non-temperature-controlled rooms. Plus, REP additionally affords a restricted lifetime guarantee on all of its barbells. An organization wouldn’t provide one of these assure if it didn’t actually stand behind its merchandise.
