9040/7-9044/7 Crumb Rubber Bumper Plate
Made from recycled rubber granules sourced from shoes, these plates stand out for their distinctive stone-like design and rubber that is approximately 10% softer than standard bumper plates. This composition provides greater elasticity, a slightly higher bounce, and a quieter impact on the floor.
Available in weights: 5, 10, and 20 kg.
Inner diameter: 50 mm – Outer diameter: 450 mm
Weight tolerance: ± 3%

CRUMB RUBBER BUMPER PLATE – Recycled Rubber Plates
The plates in this line are entirely made from recycled rubber granules sourced from shoes. These are not bumper plates made with new vulcanized rubber merely coated with a layer of recycled granules, but plates fully composed of recycled rubber granules bonded together through high-temperature processing. For this reason, in order to achieve the target weight while maintaining the 450 mm diameter and an acceptable thickness, the 20 kg plate contains a small metal core inside.
The use of recycled rubber granules gives these plates their distinctive stone-like appearance, with color tones that may vary depending on the production batch. Additionally, the light base color, which tends toward white, may take on yellowish shades over time due to oxidation from exposure to light and environmental factors.
Crumb bumpers, also known as Grid or Hi-Temp bumper plates, have been produced for over twenty years. However, the growing focus on material recycling and advancements in manufacturing techniques have led to a renewed interest in this type of plate, now offering higher quality compared to earlier versions.
From a technical standpoint, modern Crumb Plates should not be confused with old models that were overly thick and excessively bouncy. The rubber used—bonded with polyurethane—is about 10% softer than that of standard training bumper plates, offering greater elasticity, slightly more bounce, and a quieter impact on the ground. The result is a less sharp and harsh floor contact, making for a more pleasant experience without excessive rebound.
Note: In the final stage of production, the plates are treated with silicone-based products. The silicone layer can be wiped off with a cloth or will naturally wear off with use over time.

Bumper Plate Selection Guide
Bumper discs are made to limit the consequences of the loaded barbell hitting, or falling to the ground. Some weightlifting specialities involve lifts in which the fall of the loaded barbell is an integral part of the exercise. For this reason, bumper discs are completely made of rubber with metal inserts (plates or rings) to protect the central area where the barbell insertion hole is located.
From a constructional point of view, the main nominal dimensions: outer diameter of the disc 450 mm, hole 50 mm, are defined by the standard indicated by the IWF (International Weightlifting Federation).The spread of weight training in athletic training and functional fitness has led to the production of different lines and models:

9040/1-9044/1 Black Rubber Bumper Plate
Composed of sizes 5, 10, 15, 20 kg, exclusively in black. This line is made entirely of rubber (with a central steel ring) and was created with the aim of obtaining the best quality/price ratio. Being more elastic than polyurethane, rubber guarantees a good level of shock absorption, but at the same time it is a material that is more subject to wear in the long term, particularly in the case of intensive use.

9040/3-9046/3 PU Bumper Plate - Color
Composed of sizes 5, 10, 15, 20, 25 kg, colours according to the IWF standard and white details. Being made of polyurethane, this line of bumpers is high performance and allows for high standards of strength. It is advisable to combine these bumper discs with high performance and tensile strength values, as the greater rigidity of polyurethane compared to rubber ensures greater durability, but also a higher degree of vibration and shock transmission.

9040/4-9046/4 PU Bumper Plate - Black
Composed of sizes 5, 10, 15, 20, 25 kg, entirely coloured black with white details. Being made of polyurethane, this line of bumpers is high performance and allows for high standards of strength. It is advisable to combine these bumper discs with high performance and tensile strength values, as the greater rigidity of polyurethane compared to rubber ensures greater durability, but also a higher degree of vibration and shock transmission.
