When you’re performing heavy lifts, you need plates that can be dropped without damage and without hurting your floors. You’ll also want to be able to load lots of plates onto a barbell without running out of room to keep building strength and making gains! ProSource SR Bumper Plates are made with a narrow design so you can fit more onto a barbell. Our multipurpose solid rubber design with steel inserts is perfect for learning and improving Olympic lifts, as well as basic bodybuilding exercises like squats, deadlifts, and bench press. Designed for low bounce with a durometer of 88, they won’t fly when you drop them, making them safer to use than softer plates. Ideal for CrossFit, gyms and home workouts, the durable design withstands repeated drops without loud clanking or cracking floors. These training plates are a high quality, economical option for athletes on a budget.
Durometer measurements indicate the density of the rubber and how much a plate bounces when dropped, with 100 being the hard with no bounce, and 65 being softer with a lot of bounce.
