The new Eleiko XF Bumpers feature an improved composition for enhanced durability. They remain an incredibly quiet disc designed for tough training and varied environments but now will last even longer. Eleiko also created a more narrow 20 kg discs, one that matches the width of the 15 kg discs, so more weight can be loaded on the barbell, now up to 200 kg.  Compressed recycled crumb rubber is soft yet durable providing fantastic sound dampening and shock absorption. Discs are sold individually.
