Rank #2 in Best Olympic Weight Plates 2026: 10 Sets Ranked, and Why the KG Label Misleads
PROIRON Olympic Bumper Plates, 2" Rubber, 5–25 kg, Single or Pair
Price and rating as shown on Amazon when we collected them. Both change.
PROIRON's Olympic bumper plates sit at number two in this guide, and they are the tidiest example of the problem the guide is built around. The option on this page is described as 'b. 2 x 10KG' and the Number of Items field says 2, which together describe a pair of 10 kg plates — 20 kg of rubber and steel in the box. The Item Weight field on the same listing says 1.63 kg. Whichever way you read it, a 10 kg plate is not 1.63 kg, and the two figures cannot both be right.
Everything else on the page hangs together. The plates are solid rubber with a hardness of 80-85HRC and thick chrome-plated steel sleeves, the centre hole is about 50 mm for an Olympic barbell, and the weight tolerance is quoted at -1.5% to +1.5% to IWF standard. The price is £59.99 and the rating is 4.7 out of 5 from 246 ratings, with 83% of the rating breakdown at 5 stars. Everything below comes from the Amazon listing itself — we have not weighed, lifted or tested these plates.

Questions people ask
How heavy is the PROIRON Olympic bumper plate set?
The listing gives two different answers. The option is described as 'b. 2 x 10KG' and the Number of Items field says 2, which describes a pair of 10 kg plates, 20 kg in total. The Item Weight field on the same page says 1.63 kg. Add up the plates you are ordering rather than trusting either figure on its own.
Do the PROIRON plates fit a standard Olympic barbell?
The listing gives a centre hole diameter of about 50 mm, and the product name describes them as 2-inch plates for a barbell.
What are the PROIRON Olympic bumper plates made of?
The listing says high-density, low-elasticity solid rubber with a hardness of 80-85HRC, plus thick chrome-plated steel sleeves. The Material field reads Rubber.
How accurate is the weight of the PROIRON bumper plates?
PROIRON states the weight is distributed within a range of -1.5% to +1.5%, which the listing says meets International Weightlifting Federation (IWF) standards. That is a tolerance on the plate, not a fix for the Item Weight figure above.
Which sizes can you buy?
The PROIRON Olympic bumper plates are listed in 5kg, 10kg, 15kg, 20kg and 25kg, as a single plate or a pair. The option shown on this page is 'b. 2 x 10KG' at £59.99.
Will they damage or mark a floor?
The listing says the low-elasticity solid rubber keeps floors undamaged and quiet when the plates are placed down. That is PROIRON's own wording; we have not tested it.
