The rubber used is of the highest quality, important cost factors such as coloring and painting of logos and numbers have been eliminated. The high quality of the rubber, almost odorless, has a great coefficient of elasticity and good mechanical strength, which secures an exceptional level of durability despite the adoption of the ring. The steel ring, placed to protect the hole, represents the most common economic and constructive solution. It has a limit of wear out mainly in the middle. A relative limit because the rubber bumper plates brilliantly passed the tests of the 20,000 drops.
