The Iron Edge Premium Dumbbell & Fixed Barbell range has been developed specifically for the rigours of the commercial gym environment. They’re made from PU (polyurethane) which is directly bonded to the steel handle creating a fixed join that won’t loosen over time. PU is incredibly tough. It won’t tear, mark, mould or abrade. It’s also highly resistant to temperature extremes. Handles are fully knurled. This aids grip across all hand positions and makes them ideal for old school strongman lifts like dumbbell or barbell bent presses.
