Quick Release Aluminum Locking Collars GBC01

Urethane is a synthetic compound material that combines some of the best properties of plastics and rubber. As a result, urethane bumper plates produce the required bounce and weight, wear resistance, cutting resistance and tear resistance. At the same time, it remains flexible enough to resist impact damage and deformation. This makes it far more durable than rubber. In addition to durability, Urethane can be combined with colorants more easily, resulting in incredible bright colors. Urethane bumper plates are often thinner than rubber bumper plates. This allows you to load more plates onto the barbell. This also means that the weight is closer to the center of the barbell, which makes a big difference in load stability when using heavy weights. Another benefit of the urethane plates is that they are completely odorless in comparison to the rubber bumper plates. Also this kind of plates have an extremely low bounce even lower than a high-end rubber plate.
