17.75 In Diameter
Standard bar height
PRx's step up bumper: solid virgin rubber with a low bounce close to competition plates, finished in smooth black with an embossed logo. The bar lands and stays put instead of hopping, widths stay slim enough for real loading, and pairs from 10 to 45 lb build into 160 and 260 lb bundles.
Weight Pairs:45lb
Genuine PRx Performance
Synergy Custom Fitness is a PRx Performance retail partner. Every PRx free weight on our site is the same gear PRx sells directly, fulfilled and shipped to your door by PRx itself.
Low Bounce, More Control
Solid rubber with performance close to PRx's competition plates. A dropped deadlift lands and settles instead of chasing you across the platform. Control you feel immediately.
Slim on the Sleeve
At 3.18 inches for a 45 and under an inch for a 10, Prime plates leave sleeve room that thicker budget bumpers eat up. Room you will eventually use.
A Cleaner Look
Smooth black rubber with an embossed PRx logo, no paint to chip and no fleck. The plate wall reads as one deliberate, understated system, and stays that way.
Uniform 17.75 Inch Diameter
Every weight lands the bar at the same height, so deadlifts pull from regulation position whether the bar carries 10s or 45s. Every rep starts the same way.
Bundles That Outfit a Gym
The 160 lb bundle covers 45, 25, and 10 lb pairs. The 260 lb bundle adds 35 and 15 lb pairs, a complete graduated set in one order.
Stores With Everything Else
Synergy plate storage racks and wall mounted holders keep bumper pairs ordered by size, off the floor, and next to the platform, where they belong between sessions.

Frequently Asked Questions
Prime is solid rubber: lower bounce, slimmer widths, and a smooth black finish. Crumb rubber is the value and durability workhorse with a livelier bounce. Both drop safely and share the same warranty terms.
Thin bumpers flex more on impact. Dropping a bar loaded with only the light pairs can damage their inserts and voids the warranty. Load them alongside heavier bumpers instead.
PRx warrants the 25, 35, and 45 lb plates for 2 years and the 10 and 15 lb plates for 90 days. Do not drop a bar loaded with only 10 or 15 lb plates, that can damage the inserts and voids the warranty.
Yes. Any plate with a standard 2 inch Olympic collar opening stores cleanly on Synergy plate storage racks and wall mounted plate holders, and loads on any Olympic barbell.
