A revolution in dumbell training - once you've used these dial-tech dumbells there will be no going back to traditional dumbells as they are so easy to use. Just turn the dial and pick up the weight - it really is that simple! They are incredibly space efficient and versatile, replace a whole rack of traditional dumbells with just 1 pair of York dial-tech dumbells. The weight increases in 2.5KG increments, so you can select 5KG, 7.5KG all the way to 32.5kg for each dumbell
