Rotating Sleeve: The rotating sleeves of dumbbell bars allow weight plates to rotate when going heavier, which relieve stress during curling and other dynamic movements
Soild and Sturdy: Unlike those fragile hollow bars, these bars are made of reliable quality solid steel and can hold weights up to 100 Lb. The well-plated chrome finish protects the bar from rust and corrosion
Include 2 spring collars for precise securing to the bar. Each collar is tightly produced for curling and pressing without worrying about slipping plates.
For Olympic Plates: These dumbbell handles are compatible with olympic weights with 2" holes. Get these bars and utilize your weights to make your own adjustable dumbbells. No need to buy a complete set of traditional DBs. Save your money and storage space
A Great Starter Set: This set includes 2 olympic dumbbell bars and 2 spring collars. The bar is 16" in length with a 25mm handgrip diameter. Each bar weighs 8.3 LB unloaded, but reaches the weight of 8.3 LB when combined with 2 pair of spring collars
