A Great Starter Set: Stop limiting your range of motion with bulky bars! Our 16-inch loadable dumbbell handles provide the perfect balance of space and maneuverability. This set includes 2 solid steel Olympic handles and 4 spring collars. The bar has a 25mm handgrip diameter. Each bar weighs 8.3 LB unloaded, ready for your home gym workouts right out of the box. Heavy-Duty Solid Steel: Built to withstand your toughest training sessions. Unlike fragile, hollow alternatives, these durable bars are constructed from premium solid steel with a high-quality chrome finish to resist rust and corrosion. Each handle boasts a strict weight capacity of up to 100 LBS. Fits 2-Inch Olympic Plates: Maximize your existing equipment! These 50mm diameter sleeves are fully compatible with standard 2-inch Olympic weight plates. Easily create your own adjustable dumbbells on demand, saving you the massive expense and storage space of buying a full rack of fixed dumbbells. Smooth Rotating Sleeves: Engineered with rotating sleeves that allow your weight plates to spin freely when lifting heavier loads. This crucial feature significantly reduces torque and relieves stress on your wrists and elbows during bicep curls, overhead presses, and other dynamic movements. Secure Grip & Safe Lock: The 25mm handgrip features medium knurling, providing a comfortable, anti-slip hold without tearing your hands. Combined with the 4 included precision-fit spring collars that tightly lock your plates in place, you can lift, press, and row with total confidence—no slipping, no rattling.

The chrome-plated finish resists rust and corrosion, while the built-in rotating sleeve reduces wrist torsion during dynamic movements like curls and presses, lowering injury risk and improving exercise form.
