The Crossmaxx Black Bumper Plates are durable, high quality vulcanised rubber bumper plates that are suitable for intensive commercial use. Vulcanised rubber is rubber that has undergone a process that strengthens it and as such the bumper plates more durable.
The stainless steel inner ring is built into the plate in such a way that it cannot come loose, so you do not have to worry about broken plates! The Crossmaxx Black Bumper Plates Sets are made according to IWF standards (diameter 45 cm) and are thinner that many other brands of bumper plates.
This makes them easier to use and allow more plates to be loaded onto the bar! The high density of the rubber means this series gives a low, controlled bounce, even when dropped from an overhead position. These bumper plates are particularly suitable for CrossFit and similar workouts.
