The R-Sport plate (sold singly) has been manufactured using a different formula than our black series or premium series plates, with the outcome being a harder plate with minimal bounce while still maintaining durability. R-Sport plates are also slightly thinner, so you might be able to squeeze an extra one onto the bar. Features The Raze R-Sport training plates are an excellent entry-level in the world of lifting. Reinforced with a stainless steel sleeve. They conform to the IWF specs of 45 cm diameter with a 5.04 cm center hole. A reliable workhorse of a plate, R-Sport plates won’t let you down.
