The Valor Fitness BPX Rubber Bumper Plates are perfect for any athlete in the world of Olympic weight lifting, cross training, or strength and conditioning. Available in 10, 15, 25, 35, 45, and 55 lbs and easily identified by color-coding, these heavy-duty bumper plates are made of a synthetic rubber with a gloss textured finish to balance strength and a sharp look in your home, light-commercial, or even box gym. Each plate also features several inches of rubber that covers a centralized stainless-steel disk to ensure the stability and longevity of the weight plates. This steel center hub is much stronger than the steel insert you may see on many other bumper plates and is built to fit the 2" Olympic barbell sleeves while protecting both the weight and the bar. Our bumper weight plates have been tested and proven to confirm the quality, so they won't fail you during your WOD's or personal best lifts! The BPX Bumper Plates are also slightly thinner than many of our other plates, allowing you to fit more weight on your bar, put your strength to the test, and hit your next PR! Note: the 10 lb and 15 lb plates (BPX-10 and BPX-15) are not meant to be dropped on their own without adding additional weight to the bar. Using at least a 25 lb plate (BPX-25) in conjunction with 10 and 15 lb plates will not cause damage.
