AlphaFit’s Competition Plates are our hardest wearing range of bumper plates yet. Manufactured to IWF standards measuring 450mm in diameter with a 50.4mm collar opening, our Urethane Plates are in full colour and clearly labeled in kilograms for easy identification under fatigue or pressure.
Urethane is a completely different material from rubber, and offers several advantages compared to rubber.
It is more fracture resistant, meaning the plates resist fatigue a lot longer than a traditional rubber bumper plate.
Urethane compresses better than rubber but flexes less, so especially for thinner bumpers, they have the resilience of a bumper but don't wobble or flex as much when dropped.
Urethane with its high durometer rating produces a consistent dead bounce.
Most importantly, these plates yield extremely low bounce which ensures maximum safety for athletes. Loaded bars with traditional plates can bounce several metres when dropped during high intensity or heavy workouts - very dangerous in busy boxes or in competition. The low bounce of AlphaFit Urethane Plates helps you minimise this risk to keep your athletes and equipment safe.
