The rubber used is of the highest quality. With this line, we optimize the price/quality value. Costs associated with coloring and painting of logos and numbers have been cut. The high quality of the rubber, almost odorless, has a remarkable coefficient of elasticity and good mechanical strength, which secures an exceptional level of durability even considering the adoption of the internal ring. The steel ring, placed to protect the collar opening, represents the most common economic and building solution. The rubber bumper plates brilliantly passed the tests of the 20,000 drop.
Internal diameter 50 mm – External diameter 450 mm
Bumper discs (bumper = shock-absorbers) are discs designed to limit the consequences of the impact of the loaded barbell on the ground. Some particularities of weightlifting involve lifts in which the dropping of the loaded barbell is an integral part of the exercise. Bumper discs are entirely made of rubber with metal inserts (plates or rings) to protect the central area where the inner opening of the barbell is located. From a structural point of view, its main nominal sizes, 450mm external diameter of the disc, 50mm hole, are determined according to the standard of the IWF (International Weightlifting Federation).
