These bumper plates have a manufacturing imperfection and are not intended for dropping.
They can be used for controlled exercises such as back squats, bench press, push press, and on plate-loaded machines.
The plates are not suitable for dropping, as impact may cause the internal steel insert to detach.
Any damage resulting from dropping will not be considered a valid warranty claim or reclamation.

When developing these Bumpers we had in mind all experienced Olympic weight lifters to who are familiar with competitions. For the most effective training, the color of the discs differs according to the weight, so trainers and athletes can quickly replace or add suitable discs. The diameter of the discs is adapted to the IWF standards (450 mm), but these bumpers are narrower than others, which allows to load more weight on the barbell. The stainless-steel insert has a larger diameter, that prolongs its lifetime even with high intensity trainings.

Disc thickness:
10 kg: 34,5 mm
15 kg: 40,5 mm
20 kg: 52,5 mm
25 kg: 65,5 mm
