Prior to the introduction of the new Hammer Strength dumbell and barbell range, the majority of dumbells supplied in the UK and Europe have been of the multiplate design, held together by a single retaining screw.
These products have generally performed well in commercial environments but have been let down by problems associated with weight indicators peeling off; discs loosening during use; and wear and splitting of the rubber coating. In addition, the finished shape and therefore the weight distribution of each pair of dumbbells vary considerably from set to set.
