If you lift at home and want a full Olympic set you can grow into, this 120 kg bundle pairs 100 kg of bumper plates built to IWF 450 mm sizing with a 20 kg bar rated to 317 kg. The hard chrome 7ft barbell spins on 8 needle bearings and the 450 mm plates drop cleanly from overhead for deadlifts, cleans and snatches.

It suits a lifter building a first barbell station: the 2 x 5, 10, 15 and 20 kg plate pairs let you load from light technique work up to heavy compounds, and two Lockjaw collars are included so the bar stays put mid-set.

Is this bumper plate set right for you?

This bumper plate set is right for you if:

  • You lift Olympic movements and want plates that bounce safely when dropped from height
  • You want a complete 120 kg package: a 20 kg bar, 100 kg of plates and collars ready to train from day one
  • You train deadlifts, cleans and snatches and need the full 450 mm diameter for correct bar height off the floor
  • You want a bar rated to 317 kg, so it has room to grow with your lifts

Look at another option if:

  • You train light and only need a few plates for accessory work, a smaller set makes more sense
  • You never drop loaded lifts and train on cast-iron plates for powerlifting, standard iron plates suit that better
  • You already own a 20 kg Olympic bar and collars and only need the plates on their own
  • You expect to load well past 100 kg soon and want to buy heavier plates from the start
Adela Ledvinkova, Our In-House Fitness Coach

Adela's Take

What stands out is the 450 mm plates all share one diameter, so a 5 kg loads the same height as a 20 kg. Deadlifts start at the right bar height every time.

The 100 kg of plates tops out fast once you pass intermediate pulls. If you lift heavier, add another pair of full-diameter bumpers down the track so the bar height stays the same.

120 kg Olympic Bumper Set with 20 kg Barbell

This is a complete lifting set: 100 kg of Olympic bumper plates plus a 20 kg barbell, giving you 120 kg of loadable weight out of the box. The plates use a high-density rubber body wrapped around a steel core, so they take a dropped lift without cracking.

That combination suits deadlifts, cleans, snatches and squats where you need to bail the bar safely to the floor.

  • Total set weight: 120 kg (100 kg plates + 20 kg bar)
  • High-density rubber with a steel core
  • Olympic bumper plates, 450 mm diameter
  • 2 x Lockjaw collars included

What this means for you: You get a full barbell station ready to load from day one, with no extra plates to source separately.

Cortex 120kg Black Series V3 Bumper Plate Set Incl. SPARTAN205 Hard Chrome 7ft 20kg Olympic Barbell Engineered for Performance feature

50 mm Steel Ring Core for Easy Loading

Each plate has a 50 mm steel insert ring at the centre, so it slides on and off the Olympic sleeve cleanly instead of binding or scraping. The steel ring also holds the plate true, which keeps the bar balanced as you add weight.

  • Plate hole diameter: 50 mm
  • Steel core inside a high-density rubber body
  • Matches 50 mm Olympic barbell sleeves
  • Plate diameter: 450 mm for a standard pull height

What this means for you: Changing plates mid-session stays quick, which matters during supersets and dropsets.

Cortex 120kg Black Series V3 Bumper Plate Set Incl. SPARTAN205 Hard Chrome 7ft 20kg Olympic Barbell Steel Ring Core for Easy Loading/Unloading feature

IWF-Standard Plate Sizing

The plates are built to IWF specification, so the 450 mm diameter and 50 mm hole match the dimensions used in competition. That means the bar sits at the correct height off the floor for Olympic lifts.

If you train the snatch or clean and jerk, pull height consistency is what lets you groove the same bar path every rep.

  • Designed to IWF standards
  • Plate diameter: 450 mm
  • Plate hole diameter: 50 mm
  • Black bumper finish across every plate
Cortex 120kg Black Series V3 Bumper Plate Set Incl. SPARTAN205 Hard Chrome 7ft 20kg Olympic Barbell Built to IWF Standard Compliance feature

Included Plates: 5 kg to 20 kg Pairs (100 kg Total)

The set includes four matched pairs: 2 x 5 kg, 2 x 10 kg, 2 x 15 kg and 2 x 20 kg, for 100 kg of plates in total. That spread lets you load in small jumps for accessory work or stack heavy for your main lifts.

With a 20 kg bar added, your total loadable range runs from 30 kg up to 120 kg.

  • 2 x 5 kg, 2 x 10 kg, 2 x 15 kg, 2 x 20 kg
  • Total plate weight: 100 kg
  • Minimum loaded bar: 30 kg (bar plus 5 kg pair)
  • Maximum loaded bar: 120 kg

What this means for you: The small 5 kg pairs let you progress a lift in 10 kg steps, which keeps strength gains steady.

Cortex 120kg Black Series V3 Bumper Plate Set Incl. SPARTAN205 Hard Chrome 7ft 20kg Olympic Barbell What Weight Plates Are Included? feature

SPARTAN205 Hard Chrome 7ft 20 kg Barbell

The included 20 kg, 7 ft barbell runs a hard chrome finish and eight needle bearings (four per sleeve) for spin under load. Those bearings let the sleeve rotate freely so the bar follows your hands through cleans and snatches instead of fighting your wrists.

The 2.87 cm grip diameter is standard sizing that most lifters find comfortable for both pressing and pulling.

  • 20 kg, 7 ft Olympic barbell
  • Hard chrome finish
  • 8 x needle bearings (4 per sleeve)
  • Grip diameter: 2.87 cm
  • Loadable sleeve length: 41 cm each

What this means for you: Needle bearings spin smoothly, which helps the bar stay under you during fast Olympic lifts.

Barbell Rated to 317 kg

The SPARTAN205 bar carries a 317 kg (700 lbs) maximum load rating, so it has headroom well beyond the 120 kg this set provides. As you buy more plates over time, the bar keeps pace with heavy squats and deadlifts.

  • Barbell max load: 317 kg (700 lbs)
  • Sleeve diameter: 50 mm
  • Max holding length: 130.8 cm
  • 12 month warranty

What this means for you: The rating gives you room to grow your plate collection without needing a new bar.

Frequently Asked Questions

What's included in the 120kg set?

You get 100 kg of black bumper plates (a pair each of 5 kg, 10 kg, 15 kg and 20 kg), the SPARTAN205 hard chrome 7ft 20kg Olympic barbell, and 2 Lockjaw collars. That's a complete 120 kg loading setup out of the box, ready to pair with any standard 50 mm Olympic rack or lifting platform.

Are these plates okay to drop?

Yes. These are Olympic bumper plates, high-density rubber moulded around a steel core, built to be dropped from overhead on cleans, snatches and deadlifts. The 450 mm diameter is the IWF standard, so they land flat and bounce predictably. I still recommend a platform or decent rubber flooring underneath to protect your floor and keep the noise down.

How much weight can the barbell handle?

The SPARTAN205 barbell is rated to a 317 kg (700 lb) max load, so it comfortably takes the full 100 kg of plates with huge headroom to spare. The 2.87 cm grip diameter suits most general lifters, and the 8 needle bearings (4 per sleeve) give a smooth, consistent spin for Olympic movements.

Will these fit my rack and barbell?

The plates have a 50 mm hole diameter, the standard Olympic sizing, so they load onto any 50 mm sleeve, including the included SPARTAN205 bar. The barbell is a 7ft Olympic bar with 50 mm sleeves, so it sits correctly in any standard Olympic rack or stand. If you're unsure, measure your current sleeve diameter first.

How does it ship and what should I expect on delivery?

This is a heavy set, 120 kg total, so it ships freight on a pallet or in multiple boxes. Check everything against the included plate breakdown on arrival and inspect the barbell sleeves and plate edges before signing. There's no assembly required, just unpack, load the collars and lift.

What happens if a plate is damaged or something's missing?

Take photos before you unpack further and email support@cardioonline.com.au within 48 hours of delivery. We'll organise replacement plates, a new barbell or missing collars and stay across it until your set is complete. You don't chase the courier or manufacturer, that's our job to sort.

What warranty does this set come with?

The set is covered by a 12-month warranty, handled locally by us. If a plate or the barbell develops a genuine fault within that period, contact our team and we'll handle the claim and resolution directly.

Can I change my mind after it arrives?

If this set carries the 100 Day Money-Back Guarantee badge on its page, you have 100 days to return it in as-new condition with all plates, collars, the barbell and original packaging. No restocking fee. Return shipping is paid by you, and we can book the freight on your behalf to make it easy.
