The Quick-Dial Adjustable Dumbbells will change your idea of dumbbells forever. These adjustable dumbbells re-invented the dumbbell by condensing 30 separate dumbbells down to just 2... saving you space and money.
The Dial-Adjust Dumbbells unique weight system lets you adjust each dumbbell from 4.5kg to 40kg quickly, easily and safely. Just rotate the dial to the weight you want. The tumblers automatically fasten to the weight you want to lift.
The secret is the locking mechanism that seeks and locks only the weight you select. It works just like a safe ... except you always know the combination.
For added safety, the engineers created a spring loaded locking pin that prevents the knob from rotating when you lift the Dumbbells from their base. So you never have to worry about dropping plates or clamps to tighten like you can with old-fashioned dumbbells.
