Rank #9 in Best Olympic Weight Plates 2026: 10 Sets Ranked, and Why the KG Label Misleads
GYM MASTER Fractional Change Plates, 2" Rubber, Full Set 15 kg
Price and rating as shown on Amazon when we collected them. Both change.
The GYM MASTER fractional change plate set sits at number 9 in this guide. It is a 15 kg set of solid rubber plates — 0.5 kg, 1 kg, 1.5 kg, 2 kg and 2.5 kg, sold in pairs — intended for micro-loading an Olympic bar when the next jump available on the rack is too big. At £89.99 with 4.7 out of 5 from 48 reviews, it is not the budget option, and one of the reviewers says so in as many words.
Here is what makes this entry different from most of the others. On the listings above it, the headline kilograms and the Item Weight field disagree. On this one they do not: the bullet reads "Full Set Total 15KG" and the specification table reads 15 kg. What does not line up is the count — Number of Items is 2 and Unit Count is 2.0 count, which is what you would expect for a single pair rather than the five pairs a 15 kg total implies. The dimension list also prints the 1 kg plate as 16m in diameter while every other size is given in cm. Everything on this page comes from the Amazon listing, not from any testing of our own.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Good value,as described”
Verified purchase“Great quality. They look good. Not the cheapest but very usable weight increments. That allows for a very steady progressive overload.Good if you are looking for a lighter set of quality weights.Pairs really well with a heavier set of weights. So you can really fone tune your progress.Don't take much space.”

Questions people ask
How much does the GYM MASTER fractional set weigh in total?
The bullet and the colour field both say the full set totals 15 kg, and the Item Weight field also reads 15 kg — the only listing in this guide where those two numbers agree.
How many plates are in the box?
The listing gives sizes for 0.5 kg, 1 kg, 1.5 kg, 2 kg and 2.5 kg plates sold in pairs, which adds up to ten plates and the stated 15 kg. The specification table, however, lists Number of Items as 2 and Unit Count as 2.0 count.
Will these fit my barbell?
GYM MASTER states they are suitable for use on all 2" / 50mm Olympic diameter bars.
Are the plates accurate?
The listing says they are calibrated to +/- 10G. That is GYM MASTER's claim on the product page, not a measurement we took.
Which is the largest plate in the set?
By the dimensions given, the 2.5 kg plate at 23cm diameter x 2.5cm is the largest of the five sizes.
Can I use these in a commercial gym?
The listing's own note says: Not Suitable for Commercial Use.
