With the 2.5 kg technical bumpers we have solved all problems that arise when someone is learning the snatch, deadlift, clean etc. techniques. Due to it’s standard diameter (just like all Olympic bumpers) of 450mm coaches don’t need to invent new solutions anymore to fix the barbell to the right highs so the student doesn’t loose the right posture.They are made of very solid recycled plastic and are sold in pairs. Weighting only 2,5 kg and with a thickness of 20mm, these black bumpers are not suitable for dropping.
