ADD-ON
The Underworld is made up of all new, but second-quality pieces of REP equipment that have minor aesthetic flaws. Although these products may have slight imperfections to their finish or design, they are all unused, functional, and arrive ready to be used in your home or commercial gym. The Underworld features an ever changing, wide range of gym equipment, including our clearance barbell line, Death Valley. The Death Valley bars fall slightly short of REP’s exceedingly high standards for manufacturing due to minor cosmetic issues, such as inconsistencies with the knurling or finish blemishes on the bar or sleeves. Still, even these perfectly imperfect picks exceed the standards of most other gym equipment companies’ top-of-the-line products. Minor defects or slight inconsistencies you’ll see in the Underworld might be overlooked by other manufacturers. But instead, we offer this gear to you at a reduced rate. These barbells feature a distinctive "Death Valley" end cap that clearly marks this line.
The Double Black Diamond Power Bar is REP’s top-tier powerlifting barbell with ultra-aggressive knurling inspired by Colorado’s toughest slopes. Weighing 20kg (44.1lb), it features deep, mountain-style knurling for maximum grip and center knurling for stability. The 29mm diameter meets IPF standards and supports up to 1,500lbs, with bronze bushings for smooth rotation. Available in stainless steel, stainless with chrome sleeves, or Cerakote finishes with Duracoat® for enhanced durability and corrosion resistance, this bar also has distinctive metal endcaps. For more information on this barbell, check out the Double Black Diamond Bar listing.

Death Valley is the name of our clearance barbell line. These barbells feature a distinctive "Death Valley" end cap that clearly marks this line.
The Double Black Diamond Bar will be very similar to what is shown on the website; however, this item falls slightly short of REP’s exceedingly high standards for manufacturing. These bars may have inconsistencies with the knurling, or blemishes on the bar or sleeves. Still, even these perfectly imperfect picks exceed the standards of most other gym equipment companies’ top-of-the-line products. There will be minor defects or slight inconsistencies, so the product is offered to you at a reduced rate.
