Constructed of a crude rubber mixture for strength and durability, the Valor Fitness BP Bumper Plates are ideal for studios, gyms, and boxes looking for a bumper plate that will withstand punishment, provide safety, and save damage to gym flooring. Available in 10 lb, 15 lb, 25 lb, 35 lb, 45 lb, and 55 lb, each plate is built with a 2” stainless-steel insert to easily load onto bars while preventing damage to barbell sleeves. These bumper plates feature a low bounce to ensure safety to users, making these ideal for cross training, strength and conditioning, and other training programs involving high repetition volume. With clear and visible white font, users can easily identify the amount on each plate during workouts and in between sets. Note: the BP-10 (10 lb) and BP-15 (15 lb) are not designed or intended to be dropped on the bar without adding additional weight. However, using the BP-25 (25 lb) in conjunction with either the BP-10 or BP-15 will prevent damage from occurring to lighter bumper plates. Note: due to the rubber construction, these weight plates may have a distinct scent that will fade over time - some may be more sensitive to the scent than others. If you are experiencing this scent, you can wash these plates with any hand or dish soap and water until it dissipates. If you are looking for versatile and durable rubber bumper plates, the Valor Fitness BP Bumper Plates are perfect for you.
