Epic Fitness offers the best urethane bumper plates made with the highest quality urethane available. These plates are molded to perfection and constructed for long-term use. Each plate is molded around a single piece of hard chrome with a 140mm insert. Epic Fitness bumper plates glide on the barbell like butter, so you can focus on technique execution and making gains. The width of the plates is conservative to maximize loading capacity on the bar sleeve.
