Specs At A Glance

Warranty12 Months Parts Replacement

Lifters building out an Olympic barbell setup get two 5kg bumper plates with a 50mm hole and a 450mm IWF-compliant diameter, so they load and spin true on a standard bar. At 23mm thick each, the pair stacks tight and leaves room for heavier plates further out on the sleeve.

They suit anyone adding smaller jumps to a home or commercial platform, with heavy-duty scratch-resistant rubber over a seamless steel ring core and grooved edges that keep a grip when you carry them. Covered by a 12 month parts replacement warranty.

Is this bumper plates right for you?

This bumper plates is right for you if:

  • You train Olympic lifts or CrossFit-style WODs and want rubber bumper plates built for dropped lifts
  • You've got a 50mm Olympic bar and want to add two 5kg plates for lighter sets or fine-tuning loads
  • You want IWF-compliant 450mm plates so every weight sits at the same height on the bar
  • You train at home, in a gym, or a commercial setting and need rubber that handles repeated drops

Look at another option if:

  • You only lift with a standard 25mm bar and don't plan to move to Olympic sizing
  • You want the heaviest building blocks for your set and would be better starting with 15kg or 20kg plates
  • You train slow, controlled barbell reps and never drop the bar, where cheaper cast-iron plates do the job
  • You're after a full plate set in one go rather than adding a 5kg pair to what you already own

Cortex 5kg Black Series V3 Bumper Plates (2 Pack)

These 5kg bumper plates give you a light-loading option for Olympic lifts, warm-up sets and accessory work. They drop to the floor without the clang of iron plates.

Sold as a pair, so you get 10kg total to balance both ends of the bar.

  • Plate weight: 5kg each
  • Included plates: 2 (10kg total)
  • Colour: black
  • Suited to home, gym and commercial use

What this means for you: A practical starting pair for lighter lifts, or small increments added to heavier sets.

Cortex 5kg Black Series V3 Bumper Plates (2 Pack) Cortex Black Series V3 Bumper Plates feature

Seamless Steel Ring Core with 50mm Olympic Hole

The seamless steel ring insert lets the plate slide on and off the sleeve smoothly. The 50mm hole fits standard Olympic bars and sleeves.

  • Core: seamless steel ring
  • Hole diameter: 50mm (Olympic)
  • Fits standard Olympic bars and collars

What this means for you: The plate slides straight onto an Olympic bar without catching on the rubber.

Cortex 5kg Black Series V3 Bumper Plates (2 Pack) Seamless Steel Ring Core feature

Heavy-Duty Scratch-Resistant Rubber with Grooved Edges

The rubber is heavy-duty and scratch-resistant, and built to absorb the impact of dropped lifts. Grooved edges give your hands something to grip when you're loading or moving them.

  • Material: heavy-duty, scratch-resistant rubber
  • Grooved edges for better grip
  • Rated for home, gym and commercial use

What this means for you: Rubber takes the sting out of a dropped lift for your bar, plates and floor, especially with heavier bumpers loaded alongside.

IWF-Compliant 450mm Diameter, 23mm Thick

The 450mm diameter meets IWF standards, so the bar sits at competition height off the floor for cleans and deadlifts. At 23mm thick per plate, they stack tight and leave room for more on the sleeve.

  • Standard: IWF compliant (450mm diameter)
  • Plate thickness: 23mm each
  • 12 months parts replacement warranty

What this means for you: Bar height matches what you'd train on in a serious gym, which keeps your pulling positions consistent.

Frequently Asked Questions

What does a 2-pack of these plates actually give me?

You get two 5kg plates, so 10kg total. That's a handy increment for small jumps in load, finishing sets, or balancing a lightly loaded bar. If you're building a full set, these pair neatly with heavier Black Series V3 plates to fine-tune your working weight.

Will these fit my Olympic barbell?

Yes. The hole diameter is 50mm, so they slide straight onto any standard Olympic bar or sleeve. The 450mm diameter is IWF compliant, matching the standard height of a loaded Olympic bar, so the bar sits at the right position off the floor for deadlifts and cleans.

Can I drop these plates from overhead?

They're bumper plates with a seamless steel ring core and heavy-duty rubber, built to take drops in Olympic lifting. That said, 5kg bumpers are thin at 23mm, so repeated hard drops with only light plates loaded puts more stress on them. For heavy dropping, keep thicker plates on the bar too.

How grippy are they when my hands are sweaty?

The grooved edges give you something to hook your fingers into, which makes loading and carrying easier than smooth-faced plates, especially mid-session when your hands are sweaty. At 5kg each they're light to handle anyway, so moving them on and off the bar is quick and fuss-free.

How much space do two plates take up?

Not much. Each plate is 23mm thick and 450mm across, so a pair stacks flat against a wall or slots into a plate tree with room to spare. They're an easy addition even in a compact home gym or garage setup where storage is tight.

What does the warranty cover?

These come with a 12-month parts replacement warranty. If a plate has a manufacturing fault in that period, it's covered. If something isn't right, email support@cardioonline.com.au and we'll sort a replacement.

What happens if they arrive damaged?
