Home lifters building a barbell and dumbbell station from scratch get a complete kit here: 145kg of tri-grip rubber plates, a 20kg 7ft Olympic barbell rated to 317kg, and two 20 inch dumbbell handles. The rubber coating and integrated steel rings protect your floor and give a snug, quiet fit on the 50mm sleeves.

It suits someone who wants both barbell and dumbbell work from one set, with the Lockjaw collars snapping on fast between sets and the needle-bearing barbell spinning smoothly through cleans and snatches.

Is this barbell and plate set right for you?

This barbell and plate set is right for you if:

  • You want a complete barbell starting kit in one go: a 20kg Olympic bar, 115kg of rubber plates, dumbbell handles and collars
  • You train compound lifts like squats, deadlifts and presses and need load up to 135kg on the bar (plates plus the 20kg barbell)
  • You want tri-grip rubber plates that are easy to carry and quieter to set down and stack than bare steel
  • You run a home or garage gym and want both barbell and loadable dumbbell work from a single set

Look at another option if:

  • You already own an Olympic barbell and collars and only need plates to top up your existing set
  • You regularly lift beyond 135kg on the bar and want a heavier plate set with more 20kg plates
  • You prefer calibrated competition plates with tight weight tolerances for precise powerlifting loads
  • You want bumper-style plates built for repeated heavy drops in Olympic lifting rather than tri-grip plates
Adela Ledvinkova, Our In-House Fitness Coach

Adela's Take

What stands out is the tri-grip plates with integrated steel rings, so loading and lifting off the floor feels secure, and the 50mm holes pair cleanly with the included 20kg Olympic bar.

The jumps are limited: no 15kg plates, so some loads are awkward. The real win is the Lockjaw collars, which lock fast and hold tight through heavy sets and dumbbell work.

Heavy-Duty Rubber-Coated Tri-Grip Plates

Every plate is encased in heavy-duty rubber, so setting a loaded bar down lands with a dull thud instead of a sharp clang.

That rubber shell also takes the edge off floor contact, which matters if you train on timber or tiles in a home set-up.

  • Heavy-duty rubber coating on all plates
  • Integrated steel ring around the 50mm hole for a snug sleeve fit
  • Reduced noise and floor contact compared with bare cast iron

What this means for you: For a home or garage gym where noise and floors matter, the rubber coating is the detail you'll notice every session.

50mm Olympic Hole with Steel Insert Rings

The 50mm plate hole is the Olympic standard, so these plates slide straight onto the included SPARTAN100 barbell and both dumbbell handles.

A steel ring is set into each hole rather than relying on the rubber alone, so the plates hold their shape around the sleeve over years of loading.

  • 50mm plate hole diameter (Olympic standard)
  • Integrated steel rings protect the hole from wear
  • Fits the included 7ft barbell and 20" dumbbell handles

What this means for you: If you later add a rack, bench or extra Olympic plates, the 50mm standard keeps everything compatible.

Tri-Grip Design for Easy Carrying and Loading

Three cut-out grips in each plate give you a proper hand-hold, so carrying 20kg from the rack to the bar is a controlled lift rather than an awkward hug.

In my experience coaching people training solo at home, the tri-grip is the difference between loading a bar confidently and fumbling a heavy plate.

  • Three integrated grip holes per plate
  • Easier to load, unload and carry one-handed
  • Steadier handling when you train alone

145kg Total: What's in the Set

The set totals 145kg: 115kg of tri-grip plates plus the 20kg barbell and two 5kg dumbbell handles. That's enough range to run beginners and experienced lifters off the same package.

The small plates are the ones people forget to check. Four 1.25kg and four 2.5kg plates let you add load in tiny steps, which is how you keep progressing once the big jumps stop working.

  • Plate breakdown: 4 x 1.25kg, 4 x 2.5kg, 4 x 5kg, 4 x 10kg, 2 x 20kg (115kg total)
  • Includes the 20kg SPARTAN100 barbell
  • Includes two dumbbell handles at 5kg each
  • Total package weight: 145kg
  • Fine increments down to 1.25kg for small progression jumps

What this means for you: For most home lifters, 145kg across these increments covers years of squats, deadlifts, presses and rows before you need to buy anything more.

CORTEX SPARTAN100 7ft 20kg Olympic Barbell

The included SPARTAN100 is a full 7ft, 20kg Olympic bar with a 317kg max load, so the bar is never the limiting factor when you're loading these plates heavy.

The 28.7mm shaft and centre knurling suit general strength work: the centre knurl grips your back under a loaded squat, which is where it earns its place.

  • 7ft length, 20kg bar weight
  • 317kg (700lb) maximum load rating
  • 28.7mm grip diameter with standard and centre knurling
  • Chrome finish
  • 41cm loadable sleeve length per end
  • 130.8cm maximum holding length between collars

What this means for you: A 317kg rating means you can keep adding plates for a long time before the bar becomes the ceiling.

4 Needle Bearings for a Smooth-Spinning Bar

The barbell runs on four needle bearings, so the sleeves spin freely as you pull. On cleans, snatches and fast lifts, that spin lets the bar rotate in your hands instead of torquing your wrists.

Hands-on, a bearing bar feels noticeably smoother than a bushing bar at speed, which is why I look for them on anyone planning Olympic-style lifts.

  • 4 x needle bearings (2 per sleeve)
  • Free-spinning sleeves for dynamic lifts
  • Smoother bar rotation under fast movements

What this means for you: If cleans, snatches or fast pulls are part of your training, the needle bearings are the spec that matters most here.

Two 20" Chrome Olympic Dumbbell Handles

Two 20-inch chrome-plated dumbbell handles let you load the same Olympic plates into adjustable dumbbells, so one plate set covers both barbell and dumbbell work.

Each handle weighs 5kg, with 15.5cm of loadable sleeve per side for stacking the smaller plates.

  • 2 x 20" chrome-plated Olympic dumbbell handles
  • 5kg each
  • 15.5cm loadable sleeve length per side
  • Takes the same 50mm plates as the barbell

What this means for you: You get presses, rows, lunges and curls from the same plate set, which keeps a compact home gym versatile.

Lockjaw Collars for Fast, Secure Loading

The set includes Lockjaw collars, which clamp onto the 50mm sleeve with a single lever instead of the slow screw-on type.

A firm clamp keeps the plates from shifting mid-set, so the load stays balanced when you're grinding out a heavy squat or deadlift.

  • Lockjaw lever-action collars included
  • Fast one-handed on and off between sets
  • Hold plates securely on the 50mm sleeves

What this means for you: Quick collars sound minor until you're swapping plates between every set. These save real time across a session.

A Complete Barbell and Dumbbell Set-Up in One Box

This is a full starting kit, not just plates: barbell, dumbbell handles, collars and 115kg of loadable weight arrive together, ready to pair with a rack and bench.

Buying the pieces as one set means every component already fits the 50mm standard, so there's no guesswork about compatibility.

  • Barbell, two dumbbell handles, collars and plates in one package
  • All components share the 50mm Olympic standard
  • 145kg total across plates, bar and handles

What this means for you: If you're kitting out a first home gym, this covers the loading side in a single purchase. Add a rack and bench and you're training.

What's in the Box & Setup

What arrives

  • CORTEX SPARTAN100 20kg Olympic Barbell (chrome finish)
  • 115kg Cortex Tri-Grip V2 Rubber Olympic Weight Plate Set (4×1.25kg, 4×2.5kg, 4×5kg, 4×10kg, 2×20kg)
  • 2 × 20-inch Chrome-Plated Olympic Dumbbell Handles with spring collars (5kg each)
  • Lockjaw Collars (pair)

Setup reality

  1. Nothing to assemble: unpack the barbell, plates, handles and collars and check them against the parts list. No tools required.
  2. Loading the barbell or dumbbell handles with plates is manual; simply slide plates onto the sleeves and secure with lockjaw collars. Use the integrated collar mechanism by hand, no threading or tightening needed.
  3. All up it's 145kg (115kg of plates, the 20kg barbell and two 5kg dumbbell handles), so split the boxes between two trips or two people.
  4. Keep plates upright or horizontal during storage to prevent warping; avoid dropping loaded bars from height as impact can damage the tri-grip design and rubber coating over time.

Frequently Asked Questions

What exactly is included in this set?

You get 145kg across three parts. The plate set is 115kg: 4 x 1.25kg, 4 x 2.5kg, 4 x 5kg, 4 x 10kg and 2 x 20kg tri-grip rubber Olympic plates. Then the SPARTAN100 20kg 7ft Olympic barbell, two 20" chrome Olympic dumbbell handles and a pair of Lockjaw collars. It works together as a full barbell and dumbbell loading set-up.

What does the barbell actually handle for load?

The SPARTAN100 is rated to 317kg (700lb), so it won't be the limit for most lifters. The 28.7mm shaft suits mixed training, and the four needle bearings let the sleeves spin on cleans and snatches. Centre knurling helps the bar sit on your back during squats. At 115kg of plates plus the 20kg bar, you top out at 135kg loaded on the bar.

How much weight can I load on each dumbbell handle?

Each handle has a 15.5cm loadable sleeve, which fits the 50mm plates in this set. The smaller plates suit dumbbell work best; check sleeve room before loading the 10kg plates on a pair. Handles weigh 5kg each, so factor that into your total.

Why tri-grip plates over standard round ones?

The tri-grip cut-outs give you three hand holds, so moving and loading plates is easier on the hands and back. The heavy-duty rubber coating with integrated steel rings protects your floor and keeps noise down when you set the bar down. The 50mm hole fits any Olympic bar or sleeve. For a home or garage gym, that's where this set earns its keep.

How is it delivered and what should I expect on the day?

This ships as a heavy freight item across several boxes, so expect it on a pallet or with a courier rather than standard post. Plates and a steel bar add up fast, so have a hand ready to move the boxes inside. Check all parts against the included list before you start loading, and keep the packaging until you're happy everything's accounted for.

What happens if it arrives damaged or a part is missing?

Take photos before unpacking further and send them to support@cardioonline.com.au within 48 hours of delivery. We'll organise the replacement plates, collars or bar and stay across it until your set is complete. You don't chase the courier or manufacturer yourself; that's our job. With a multi-box freight item, a quick check against the parts list on arrival saves time.

Can I return it if I change my mind?

If this product shows the 100 Day Money-Back Guarantee badge on its page, yes. You have 100 days to request a return, with the plates, bar and collars unused and in as-new condition, repackaged in the original boxes with all parts included. No restocking fee. Return shipping is paid by you, and we can book it on your behalf.

How much floor space do I need to store it?

The bar is the longest item at 7ft, so plan a rack or wall space to suit. The plates stack neatly on a tree or in a corner; 115kg of rubber plates takes up less room than you'd think. There's no assembly beyond sliding the spring collars onto the dumbbell handles. Keep the rubber off direct sun to make it last.
