Comp plates are back! These bumper plates have been designed and manufactured to give you the most resilient, accurate and aesthetically appealing set of bumpers on the market. Designed with an extremely tight tolerance of + / - 10 grams, the SMAI Competition Bumper Plates are precisely tuned for exact weight - exactly what you need for weightlifting competitions and comp training. With a new intricate rubber recipe and nickel-plated steel disc centre, these competition bumper plates give a ‚'dead-blow' effect when dropped from overhead in Olympic lifting. This capitalises on safety for those using the equipment and to those near, meaning you don't have to worry about bars spraying left, right and centre. The protective rubber flanges allow for easy handling and more surface area for point-of-impact making it ideal for CrossFit boxes. With each plate coming with raised lettering and finished in a matte texture coat to enable a secure grip, the bumper plates are finished in a true IWF colour scheme. Each plate will slide onto all IWF and SMAI barbells smoothly and firmly with the collar opening precisely sitting at 50.4mm in diameter allowing for minimal slop and movement. The absolute best quality weight set you can add to any space.
