    Design details

    Why choose cast iron instead of plastic or vinyl bumper weights?

    - Cast iron is a dense material that is more compact than vinyl, which means you can add more discs to the bar (up to 32 kg on one dumbbell bar)
    - Cast iron lasts a lifetime, unlike plastic or vinyl, which can wear out within a year.
    - Cast iron is less affected by temperature changes so you can use it in a range of conditions.

    Our cast iron plates are made from at least 80% recycled cast iron

    Since 2018, our teams have been gradually integrating recycled materials until we reached the perfect balance. Following several years of experiments, Decathlon is replacing its entire range of cast iron products with recycled cast iron made from at least 80% scrap metal and steel waste – a real feat for the world of metal! To ensure that the quality is the same as classic cast iron, tests are carried out in partner laboratories.

    Why should you use cast iron weights?

    - Cast iron better withstands shocks, drops and crushing (5 times better) than vinyl.
    - Cast iron has a textured surface for excellent grip even when your hands are damp, unlike plastic, which can be slippery.

    Choosing our cast iron weights means you can work out confidently and efficiently.

    What bars can you use with this 20 kg weight training disc?

    - 1.2 meter curl bar (ref: 8484124)

    However, it cannot be used with a 50 mm bar.

    With disc collars, you can train safely!

    Don't forget to invest in a pair of disc collars to prevent your weights from slipping on the bar as you work out. Ours are sold as a pair (ref: 8574652).
    The maximum weight supported by the disc collars in a vertical position is 15 kg.

    Store your weight discs properly to use for a long time

    Store your discs indoors in a dry place.
    Invest in a disc mount (ref: 8796727) or a storage rack (ref: 8788246) to save space on your floor.
    The bottom of a piece of furniture can also store your weights.
    Feel free to clean with a microfibre cloth if they get dusty.

    From ore extraction to transformation into finished products, the industrial production of metals is highly polluting. To reduce our environmental impact, we design products from recycled metal. This approach reduces the need for extracting new raw materials, uses 40% to 95% less energy, and cuts CO2 emissions by at least 10% compared to virgin metals. Recycled metal comes from the recycling of scrap metal. After a process of sorting, cleaning, and crushing, the scrap metal is melted and refined to obtain a material of comparable quality to virgin metal.
