These steel disks can be added to the back of the Aluminium Light Wheels to add extra weight. They effectively double the weight of the Light Wheels, giving them a feeling that is closer to the Heavy Stainless Steel wheels but for significantly less cost. 

These stick to the inside surface using the magnets that come fitted as standard in the Light Wheels. 

They are made of mild steel and then electroplated, meaning they can also be used in combination with the Critical Balance Kit to adjust the balance when using different types of handle. 

Kit comprises 

2x Back Weight Disks
