The Origin Coloured Urethane Bumper Plates Set consists of 4 x 20kg, 2 x 10kg, 2 x 5kg. Hard, durable urethane material Odourless Will not mark any other equipment Bold bright colour scheme Long lasting Supplied in a set of 4x20kg, 2x10kg and 2x5kg Coloured Rubber Bumper Plates One of the key benefits of the Origin Urethane Olympic Bumper Plates is the extremely high abrasion resistance, which means the plates will acquire far less scratches, scrapes, knocks, dents or marks than their rubber counterparts. Urethane material will not mark or stain any other equipment, meaning you can keep your fitness suite squeaky clean. Harder than rubber, these plates are far less prone to bending, denting or warping. The 450mm diameter of each plate means that the impact is spread throughout many plates. This allows for Olympic style lifting (overhead and dropping). The urethane material takes colour much better than rubber and will continue to brighten up your gym long after the rubber equivalents have faded. The plates are available in 5kg (black), 10kg (green), 15kg (yellow), 20kg (blue), 25kg (red). Another added benefit of urethane over rubber is it is odourless, meaning your gym stays fresh.
