The new Muscle Motion bumper plates have significant improvements over Economy bumper plates.

Features:

• A hard steel insert is locked into the body of the rubber weight plate via reinforcement keys.
• These plates are much thinner than other bulky economy bumpers, this is achieved by introducing a concealed steel core to the rubber plate, allowing more weight to be loaded on the bar.
• The 25kg, 20kg and 15kg plates are a uniform thickness of 65mm.
• International IWF colour coded
• Strict weight tolerance
• 450mm diameter (IWF standard)
• Plate thicknesses are:
  
• 5kg - 30mm
• 10kg - 45mm
• 15kg - 65mm
• 20kg - 65mm
• 25kg - 65mm
