Description

Cast iron has been the material of choice for weight training for generations, and for good reason - it's hard-wearing, dependable and holds up to regular use without losing shape. This 20kg set includes twelve cast iron plates (2.5kg, 1.25kg and 0.5kg) paired with two 13.5-inch steel bars, each weighing 1.27kg. The knurled grip is built to withstand repeated gripping and re-gripping, while the spinlock collars are designed to keep tightening reliably, set after set. Everything is finished in black and supplied with a carry case, so the set stays protected and organised when it's not in use. A dependable, long-lasting option for anyone who wants equipment that will still be doing the job in years to come.
