Why choose a cast iron weight rather than plastic or vinyl?
- Because of its density, cast iron is more compact than vinyl, which means you can increase the number of discs on the bar (up to 32 kg on one dumbbell).
- Cast iron can be kept for life, unlike plastic or vinyl, which can last less than 1 year.
- Less affected by temperature variations, cast iron offers constant use in different climatic conditions.
Why use cast iron weights?
- Cast iron is 5 times more resistant to knocks, falls and crushing than vinyl.
- Cast iron has a textured surface for excellent grip, even with wet hands, unlike plastic, which is often slippery.
Choosing our cast iron weights means opting for efficiency and reliability in your training.

With disc collars, you can train safely!

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.
