PU BUMPER PLATE - Polyurethane Bumper Plates, colour black<\/h2>\n

Comprising sizes 5, 10, 15, 20, 25 kg, colour black, this line of Bumper Plates is made from polyurethane-coated metal discs.<\/p>\n

Polyurethane is the best material for producing discs; its main drawback is its high cost compared to rubber, especially recycled rubber. Extremely high resistance, extraordinary compactness, low rebound, no odour, clear colouring, absence of imperfections and mould marks, perfect coupling with the steel plate, PU discs represent the best possible solution in terms of reliability, aesthetics and overall quality.<\/p>\n

The wear and light degradation of polyurethane is significantly lower than that of rubber.<\/p>\n

In addition, due to the high density of the material, PU discs have a very low thickness, which makes it possible to load a barbell over 350 kg, almost as if it were a metal disc, but with the advantage of having a softer bearing. However, the lower elastic deformation compared to rubber can also be considered a limitation for those who prefer softer, bouncier bumpers.<\/p>\n

As you can see in the image below, in the same loading space (we examined the 9015\/9 Olympic barbell), using the classic rubber bumpers with a very wide shoulder (approx. 93.5 mm) it is possible to load 4 of 25 kg, reaching a total weight including the barbell of 220 kg, while using the PU bumpers with a narrower shoulder (approx. 51 mm) it is possible to load 7 of 25 kg, reaching a total weight of 370 kg!<\/p>\n

\"Example<\/p>\n

From this perspective, typical of powerlifting, PU bumpers can be considered better than even the thinnest metal discs.
\nThe POLYURETHANE cover in fact consumes less weight on the stacking platform and makes the disc much more versatile and suitable for other uses in the weight room.<\/p>\n

Polyurethane Bumper Plates are also available in coloured versions according to IWF standards, code 9040<\/span>\/3-9046\/3<\/a>.<\/p>\n
