Our MuscleMad rubber bumper discs have a standard Olympic outer diameter of 450mm and an inner diameter of 50mm.
Bumper plates can be safely dropped from heights equal to human height. Their safety margin allows them to withstand up to 10,000 drops (for a 5-kilogram disc) and 20,000 drops (for other weight discs).
Different thickness of the disk depends on the weight of the bumper plate, which are available in denominations of 5, 10, 15, 20 and 25 kg.
To increase the life of your barbell and bumpers, we use stainless steel for the inner ring sleeve.
Important! We recommend using 5 kg bumper plates in combination with other heavier discs, as they have a reduced fall capability.
