If you train Olympic lifts or CrossFit and drop the bar from overhead, this 70 kg set gives you 2 x 5 kg, 2 x 10 kg and 2 x 20 kg plates built to take the hit on repeated drops. The dense, thinner profile means you can load more weight on a 50 mm Olympic bar before you run out of sleeve.
It suits a garage or commercial box that needs a full starting load across three pairs, with grooved edges that make the 450 mm plates easier to grip when you are stripping the bar between sets. The steel core and high density rubber are built to IWF standards, backed by a 12-month parts replacement warranty.
What stands out is the dense, thinner profile: at 450 mm diameter but slimmer than standard, you fit more weight on the bar before plates start crowding the collars on heavy lifts.
At 70 kg total, the set tops out at 35 kg a side, so stronger lifters will want extra 20s. The grooved edges make rushed changeovers between sets genuinely easier.

This 70kg set spans a 5kg to 20kg pair range, so you can scale from technique work to heavier Olympic lifts on one bar. The dense, thinner build packs more weight into less width, which frees up sleeve space when you load multiple plates.
The high density rubber is designed to withstand high-impact lifts and repeated drops.
What this means for you: A single set that covers warm-up lifts through to loaded Olympic work.
The 50mm hole seats cleanly on a standard Olympic bar sleeve, so plates slide on and off quickly and easily. Grooved edges give your fingers something to grip, which makes loading and stripping a heavy bar faster between sets.
The steel ring core gives a secure fit on the bar and keeps its strength through intense, repeated drops.
These plates are built to IWF standards, with the 450mm diameter that sets correct bar height for cleans, snatches and deadlifts off the floor. Train on a bar that sits where competition plates sit and your pull mechanics stay consistent.
What this means for you: Your setup matches what you lift on in competition, so technique carries over.
The scratch-resistant black rubber holds its look under heavy use, whether the set lives in a garage gym or a commercial floor. One colour across the set keeps the rack tidy.
What this means for you: Hard-wearing enough for a shared commercial floor, tidy enough for a home gym.

You get six plates in three matched pairs: 2 x 5 kg, 2 x 10 kg and 2 x 20 kg, for 70 kg total. All sit on a standard 50 mm Olympic hole, so they slide straight onto any 50 mm Olympic bar. It's a sensible starter spread that covers light accessory work through to heavier compound lifts.
Yes, that's exactly what they're built for. The high density rubber with a steel core absorbs the impact of a dropped Olympic lift, which is why they suit CrossFit and Olympic lifting. For home use I'd still lay down a lifting platform or rubber matting to look after your floor and keep the bounce predictable.
If you have an Olympic barbell, yes. The 50 mm hole diameter matches any standard Olympic sleeve, so these load straight on. They won't fit a 25 mm standard bar. The 450 mm diameter is full competition height, so your bar sits at the correct loading position for pulls from the floor.
Each plate is 450 mm across, so a basic vertical plate tree or a horizontal storage peg handles the full set in a small footprint. The thinner, dense design means you fit more weight per bar sleeve too. I'd keep them off the floor on a rack, both to protect the rubber and to save your back loading up.
Best for serious functional fitness, Olympic lifting and CrossFit training, at home or in a commercial gym. The grooved edges make the plates easier to grip and change, and the dense build handles repeated drops. If you're lifting heavier than 70 kg regularly, treat this as a base set and add more pairs as you progress.
