I recently purchased sets of 10, 15 and 25 pound Kraiburg bumper plates. The 15 pound bumpers have no "give" and don't bounce! The 10's and 25's feel "rubbery" and bounce when dropped from any height. The 15's feel like hard plastic and just go "THUD" when dropped. They don't seem to give any more than steel plates would. In addition, when I have the 15's on the bar with the others that normally bounce, the whole bar just goes "THUD". The bar with 10's and/or 25's on it bounces quite nicely.

Has anyone with 15 lb Kraiburgs experienced this? Is this problematic? I am currently lifting on a carpeted concrete floor so I feel like my plates need as much give as possible. To me, the fact that the bumpers bounce means the floor is being spared but when the whole bar just crashes to the floor I feel uneasy.

Most of us use lifting platforms, they are cheap, easy to make, and save the floors and equipment. They also look cool. Plans are in the Equipment section and should come up with a quick search...problem solved!!!

I have 3 sets of newer kraiburg. They all have very different characteristics. Some bounce, some thud. Dunnowhy, just the way it is.

Hmm, 15's are pretty narrow compared to other sizes so won't bounce as much. But your 10's on the bar alone DO bounce? I'll have to check that out when I get home.

My 20K's bounce all over the place when I drop them on concrete . . . I miss my lifting platform.

Bouncy bumpers are more dangerous than bumpers that go "thud". I'd rather punch a hole in a floor than a leg any day.

Actually, the 10's on the bar would not bounce. They would likely fold-over from the weight. The 10's do however bounce by themselves or on the bar with the 25's. The 15's do neither. It looks like this is normal variation although I'm shocked that the characteristics of same-brand plates vary so much.
