15lb Crumb Rubber Bumper Plate
The AmStaff Fitness Crumb Rubber Bumper Plates have the perfect durometer rating to absorb bounce and shock, preventing damage to your Olympic lifting bar. Crumb Rubber Bumper Plates are built from a nearly indestructible marriage of recycled vulcanized rubber and a 2" stainless steel insert; giving you 10,000 - 30,000 drops and reducing stress on the lifting bars. On the field tests have shown AmStaff Fitness Crumb Rubber Bumpers bounce less than other high-end rubber bumper plates on the market which means that they absorb more shock and make less noise.
10lb and 15lb plates are not meant to be dropped on their own. These sizes can be dropped only when combine with heavier weights (25lb, 35lb, 45lb & 55lb). If dropped on their own, plates may crack/break. Improper use will void the warranty.
The 10lbs and 15lbs AmStaff Fitness Crumb Rubber Bumpers are covered under Fitness Avenue’s 6 months warranty from the time of purchase. The 25lbs - 55lbs rubber bumper plates are covered for 3 years from the time of purchase.
Ratings & Reviews
I use these plates only two time since I received them. I feel like these aren't so cheap made. For exemple, it seems that the plates were molded on the insert rather than add the insert after the plates were molded. I weighted the plate with a person scale (this scale could be off) and got 15.4 lb for each (2.7% more) which make these as accurate as the Rogue Hi-Temp should be (+/- 0,5 lb). The feel of the plate is a little more denser than the Rogue hi-temps.
