What Is A Bumper Plate?
A bumper plate is a weight plate for Olympic bars that is made almost entirely of rubber (with a steel or brass collar in the middle that accepts an Olympic bar).
Why Bumper Plates?
The "end state" of the Olympic lifts is overhead or at the shoulder. Many lifters drop the weights from overhead. Since bumper plates are almost entirely rubber, being dumped from the shoulder or overhead will not damage the weights, bar, floor, bystanders, the lifter, etc...
Bumper plates are also great for garage gym use- the rubber construction is much quieter than traditional metal construction.
What Exercises Can I Do With Bumper Plates?
Snatch
Clean and Jerk
Press
Thruster
Deadlift

Bench
Overhead lunge

These Plates Might Look The Same...But They're Different
At first glance, you'll notice the first difference is purely cosmetic; the Milspec Plates have a matte black finish, vs a glossy black finish on standard black bumper plates. Milspec plates are also slightly thinner than our standard black plates, with a more rounded edge. In the end, both plates are great, and you should be confident in knowing you are using the best bumper plates on the market today.
YOU'RE WONDERING.
WE GOT YOU.
The Mammoth works out of the box with the lever arm and the belt, which comes free. That said, most owners add the Kickstand. It holds the arm up so you start every rep standing instead of picking the weight up off the floor.
That's why we sell it bundled. Pick + Kickstand & Magpin, or go all in with + Kickstand, Dual Mounted Weight Horns & Magpin. Bundling at checkout costs a lot less than adding the pieces later.
We'll be straight with you. Every lever arm moves in an arc, so you feel less than the full weight of the plates loaded. The fix is length, and the Mammoth's lever runs 39" to 48.75", one of the longest you can buy. A longer lever means a flatter arc and less forward pull.
In our recommended setup you feel about 80% of the load, and up to about 90% with the horn moved closer to you. Most lever belt squats top out around 60%. A standalone machine costs $2,000+ and eats floor space. The Mammoth hangs on your rack. See the full felt load breakdown.
Yes, and watch it before you start. It covers the belt squat and the kickstand. The bolts are big, so have a large wrench or socket set handy.
One tip owners have flagged: don't skip the big washer that goes under the weight horn.
It fits 2x2, 2x3, and 3x3 uprights with either 5/8" or 1" holes. Just pick your hole size at checkout. The one thing to check is that your upright has holes on the side, since that's where the Mammoth mounts.
No side holes? The Wall-Mount Accessory gives you a dedicated belt squat station without tying up your rack. And if it still doesn't work out, you're covered by our 365-day no-drama returns.
Wall-Mount Accessory View Yes. The arm has about 10" of length adjustment, the horn moves, and you can mount it at different heights on your rack. Mount height matters most, especially for shorter lifters who need to clear the kickstand. Our mount height guide walks you through it.
Sharing with someone a lot taller or shorter than you? Dial in a setup for each of you, then switch mount height and arm length between users.
The Mammoth is rated to 900lbs, so the frame isn't your limit. Plate space on a single horn is. Add the Dual Mounted Weight Horns for more room, and they double as handles mid-rep.
Worth knowing: dual horns sit farther back, so felt load drops to about 65%. That's great for big numbers, but run the math before you chase a plate count.
Dual Mounted Weight Horns View The lever arm has a lifetime warranty, and the whole unit is rated to 900lbs. Check that your hardware is snug after the first few sessions.
The belt comes free with every Mammoth. It's padded so it doesn't dig into your hips, and it has 3 sets of D-rings on each side for a small, medium, or large fit. It's covered by a 1-year warranty, and plenty of owners use it for weighted dips too.
Yes. It sits at an angle when it's down, and a spring-loaded lever locks it firmly in place. It's 17" tall, so you start every rep standing and set the weight back down when you're done.
Kickstand View You can, and plenty of people start there. Here's what you get with the Mammoth: a 900lb rating, a kickstand so you start standing, a long adjustable lever, a lifetime warranty on the arm, and a padded belt. It mounts and comes off in seconds. No lumber runs, no guessing if it'll hold.
The horn takes Olympic plates and gives you 14" of loadable space. Iron or thin plates fit the most weight and give your knees the most clearance. Thick bumpers work, but they fill the horn fast and can crowd your stance. Standard 1" plates won't fit.
No rack? The Wall-Mount Accessory turns any solid wall into a belt squat station. Mount it into studs, never just drywall.
Can't drill? Owners also run the Mammoth on squat stands and yokes, as long as the uprights have side holes in 5/8" or 1".
Wall-Mount Accessory View Lookalikes can copy the shape, not the lever. The Mammoth's 39" to 48.75" arm is what gets you up to about 90% felt load. You also get a lifetime warranty on the arm, a real support team behind it, and hundreds of owner reviews. Garage Gym Reviews named it the best budget belt squat for a reason.
At 32lbs, one person can handle it. Hold it in two spots when you lift it off so it doesn't flop to one side.
Want to skip that step entirely? The Swan Neck adds swivel mid-rep and lets the arm store vertically, and the Wall-Mount Accessory gives it a permanent home. Either way, it never has to come off.
55's are 3.2", 45's are 2.9'', 35's are 2.35'', 25's are 1.87'' 15's are 1.2'', and the 10's are 1.05''
The 10 and 15-pound bumper plates are 90; the 25, 35, 45 and 55-pound bumpers are 85
Durometer is a measure of the hardness of a material. It ranges from 0-100, and the higher the rating the harder the material, and the higher the material's resistance to indentation. Anything above 65 is acceptable for bumper plates. Our plates are considered to be excellent.
In general, the lighter bumper plates have a higher durometer reading because they need to be more rigid to withstand the stress of being dropped. Heavier plates have more surface area to distribute the stress, so they do not need to be as hard.
Most Fringe Sport bumper plates are the IWF standard 450mm (~17.7") width in diameter, with a +/-1.5mm variance
The ten-pound Fringe Sport bumpers are 445mm (17.5") in diameter
The ten-pound bumper plates are purposefully 5mm narrower than the other bumper plates so that when you have 10's loaded on the bar, plus other bumpers, the 10-pound plates impact the ground a split second later than the other bumpers. Since the 10-pound plates have the least surface area and are thus the weakest bumpers, this saves stress on your 10 pounders!
Sometimes the bumpers smell due to the way that they are made. It isn't permanent. The best remedy is to let them air out in the sun for about 5 days.
The bumpers are greased as a part of the manufacturing process. Sometimes the factory doesn't clean the plates well enough. Here's what we do to de-grease these bad boys:
We wash the bumpers about 3 times, with paper towels, soap, and water. If that doesn't work, then we use a de-greaser spray that can be purchased at a local home improvement store.
Drop away. We are confident that our 10-pound bumper plates can handle the abuse, and they are backed by our fully comprehensive warranty for 1 year just in case.
Some of our plates go through random spot checks by different quality assurance teams. The star simply means your plate passed inspection. There are no differences in quality between plates with or without stars!
Bumper plates come in a few standard sizes and are sold in pounds with kilogram conversions. Fringe Sport economy bumpers are sold by the pound. Here is a chart with a rough pound and kilogram weights:
| Bumper Weight | Best Weight For: |
|---|---|
| 10 lbs ~ 5 kg | Great for teaching or learning Olympic lifts. |
| 15 lbs ~ 7 kg | The same uses as the 10s, but this offers greater durability at only a slightly heavier weight. |
| 25 lbs ~ 11 kg | A very popular weight as they are very durable and throwing these on an Oly bar gives you 95 pounds (Fran Rx). |
| 35 lbs ~ 16 kg | A great size for adding more weight to the bar. |
| 45 lbs ~ 20 kg | The most popular size for gyms - 45's really lets you load up your bar and make some serious strength gains. |
| 55 lbs ~ 25 kg | When the 45s just don't cut it, we have 55lb bumpers to add some serious weight to the bar. |
EXCELLENT: QUALITY, PRICE, TIME
"I've now purchased 55, 45, 35, 25, & 10lb pairs from Fringe. I'm super pleased with every purchase. Delivery is always quicker than I expect & packaged well. The plates feel great in your hand, match well, and are plenty durable. 10lb plates are always super thin, but these feel solid. Love working with Fringe!"

WHY CHOOSE FRINGE SPORT BUMPER PLATES?
Not all bumpers are created equal. Here's why your next bumper plates should be Fringe Sport bumpers:
- Fringe Sport bumper plates feature a steel insert that is designed to far outperform the brass bumpers used by the competition. A steel insert will take much more abuse without malforming- and it is machined to exact tolerances to fit all high-quality Olympic bars.
- Fringe Sport bumpers use a rubber formulation that combines the ideal mix of low bounce with high durability. Some bumper plates bounce too much- they are potentially unsafe. Other bumpers are too brittle- and they easily chip and fall apart. Not Fringe Sport bumper plates!
- Fringe Sport bumpers 10 and 15 lb bumpers are more stable because they have high durability. This makes them more stable than most 10 or 15 lb bumpers which are the most fragile bumper plates due to their thinness.
- Fringe Sport bumpers are thinner than many of the competing bumpers- so you can load more weight on your bar!
- Fringe Sport bumpers all have the same standard diameter- you can mix and match to load your bar.
- Finally, Fringe Sport bumper plates are backed by our no-questions-asked satisfaction guarantee- plus a 1-year warranty (on the 25-35-45-55's). Use them and love them- or send them back free!
