OneFitWonder Black bumper plates are manufactured to go toe to toe with any bumper plate on the market. They are constructed with virgin rubber formulated specifically for its durability, density and low bounce. Most importantly, they go through the most customer-focused manufacturing, quality control and shipping process in the industry so you can rest assured that you are getting the highest quality plates.
Bumper plates come in a few standard sizes, and are generally sold in pounds or kilograms. OneFitWonder bumpers are sold by the pound. Here is a chart with rough pound and kilogram weights:
||Best Size For:|
|10 lbs ~ 5 kg||Great for teaching or learning Olympic lifts|
|15 lbs ~ 7 kg||Same uses as the 10s, but this offers greater durability at only a slightly heavier weight|
|25 lbs ~ 11 kg||A very popular weight as they are very durable and throwing these on an Oly bar gives you 95 pounds (Fran Rx)|
|35 lbs ~ 16 kg||A great size for adding more weight on the bar|
|45 lbs ~ 20 kg||The most popular size for gyms - 45's really let you load up your bar and make some serious strength gains|
A bumper plate is a weight plate for Olympic bars that is made almost entirely of rubber (with a steel or brass collar in the middle that accepts an Olympic bar).
The "end state" of the Olympic lift is overhead or at the shoulder. Many lifters drop the weights from overhead. Since bumper plates are almost entirely rubber, being dumped from the shoulder or overhead will not damage the weights, bar, floor, bystanders, the lifter, etc...
Bumper plates are also great for garage gym use - the rubber construction is much quieter than traditional metal construction.

How wide are these bumpers?
45's are 2.9'', 35's are 2.35'', 25's are 1.87'' 15's are 1.2'', and the 10's are 1.05''
What is the durometer reading on these bumpers?
The 10 and 15 pound bumper plates are 90 shA; the 25,35,45, and 55 pound bumpers are 85 shA
What does durometer mean?
Durometer is a measure of hardness of a material. It ranges from 0-100, and the higher the rating the harder the material, and the higher the material's resistance to indentation. Anything above 65 is acceptable for bumper plates. Our plates are considered to be excellent.
Why do different weight bumper plates have different durometer readings?
In general, the lighter bumper plates have a higher durometer reading because they need to be more rigid to withstand the stress of being dropped. Heavier plates have more surface area to distribute the stress, so they do not need to be as hard.
What is the diameter of these bumpers?
Most OneFitWonder bumper plates are the IWF standard 450mm (~17.7") width in diameter
The ten pound OneFitWonder bumpers are 445mm (17.5") in diameter
What? Why are the ten pound bumpers narrower than all the rest?
The ten pound bumper plates are purposefully 5mm narrower than the other bumper plates so that when you have 10's loaded on the bar, plus other bumpers, the 10 pound plates impact the ground a split second later than the other bumpers. Since the 10 pound plates have the least surface area and are thus the weakest bumpers, this saves stress on your 10 pounders.
Can I drop the 10 pound bumpers like I see my favorite athletes do?
