I chose these plates because they are thin, so save space on the bar, and looked great online. Upon arrival, they also appeared impressively colorful. Unlike rubber-coated plates, these urethane plates are firm to the touch. While I was unpacking these, my box cutter caught one of the yellow plates---the box cutter recoiled off the plate and the plate itself remained unscratched. These plates are tough!
These plates are exactly what I would want for olympic lifting. They fit the bar snugly and land without too much noise. Because the collars fit onto the bar precisely, there is not metal clanking if a bar is dropped. Additionally, there is little slack in the bar for deadlifts and olympic lifts. I have paired these with an American Barbell Olympic bar.
