CAP Barbell Competition Bumper Plates Review

CAP barbell is a leading distributor of home gym equipment. It doesn’t manufacture any of the products it sells. It sources them from its Chinese vendor and rebrands them before selling them. That’s how a majority of home gym equipment companies operate in the US and most other countries. 

You might be wondering if it is a reliable brand for buying competition bumper plates

Yes, it is! 

CAP barbell has been in this business for more than 30 years and is counted among one of the oldest home gym equipment sellers. It wouldn’t have survived so long if it had sold substandard products. The products may not be as good as the ones that you can buy from Fringe Sport or REP Fitness but they are still great for most of us who are looking for good-quality affordable products for personal use. 

I have used many of its products such as Cap Barbell Olympic Open Trap Bar, CAP barbell Power Rack, CAP Barbell Beast Olympic Bar, etc. These products met my expectations and that’s why I recommend its competition bumper plates for home use. 

In this article, I will be providing a detailed review of the CAP barbell competition bumper plates. I will also be comparing it with some of the other competition bumper plates that I recommend.

Quick Review Summary

CAP Barbell competition plates are designed to adhere to many of the IWF standards but the seller doesn’t make any such claims. They are made of virgin rubber and I expect them to have a dead bounce. I am not sure of the durometer rating if that interests you because of the lack of information from CAP barbell. They have a reinforced steel hub, which helps make these plates durable enough to last for a long time, even when they are dropped regularly, although I don’t recommend that. Currently, they are quite expensive, so wait until their price comes to a normal range. 


  • Good product for recreational lifters
  • Designed as per IWF standards so compatibility won’t be an issue
  • Have a dead bounce
  • Have a high weight tolerance of +/- 5 grams of the stated weight


  • Inadequate information provided by the seller leaving a lot of scope for assumptions
  • Currently too expensive than what I would like them to be


We are giving this a rating of 4.1 out of 5.0.

CAP Barbell competition bumper plates are a good option for casual trainers 

CAP Barbell competition bumper plates

Just like other affordable products such as Titan competition bumper plates, they are made of good quality virgin rubber with a steel disc at the center. The disc is made of two steel plates that are joined together using bolts. The steel hub is embedded deep inside the rubber so even if you drop the plates frequently, they won’t loosen up and become useless. 

The color coding is as per IWF standards with the logo and weight mentioned in white. The diameter and hole sizing are also pretty standard so compatibility won’t be an issue. The weight accuracy of +/- 5 grams is exceptionally good. 

Being competition bumper plates, they are meant for rough use. But, I am not sure how long they will last when dropped frequently. They are good for trainers like me who do not usually drop their loaded barbell because if they do so, their neighbors could call the police or their wives/kids could threaten to leave them :). 

If you train rather roughly, you should go with Rogue competition bumper plates, Fringe Sport competition bumper plates, or Eleiko IWF-certified competition bumper plates, depending on your budget and training needs. 

CAP Barbell should provide more details so buyers can make an informed decision   

The seller hasn’t provided enough information that buyers like you and I can use to compare its competition bumper plates with the other similar products. For example; I don’t know their durometer/shore rating, which means I don’t really know much about their bounciness. 

Competition bumper plates are expected to have a very low bounce rate, which could be categorized as dead bounce. For this, the rubber has to be extremely dense and firm. This is measured using a durometer/shore rating. The higher the rating is, the lower will be the bounciness. 

Affordable competition bumper plates such as the Titan Fitness ones have a rating of 90 whereas high-end ones such as Rogue Fitness competition bumper plates are rated at 94. REP Fitness competition bumper plates are rated at 92. This rating helps me make a rough assumption of how much the plates will bounce. Without that, I can’t be sure what to expect from the plates. What if they bounce too much and hit me right on my face! 

Similarly, CAP barbell hasn’t mentioned if these plates are drop-tested to check their durability. 

Without this information, it becomes really difficult for a buyer to decide if he/she should really invest his hard-earned money on these weight plates. 

CAP barbell competition bumper plates are more expensive than Titan and REP Fitness competition bumper plates. 

Buyer's feedback regarding the prices of CAP barbell competition bumper plates

These two brands are some of the best Rogue Fitness alternatives. So, if I have that high budget, I would rather spend money on their products instead of CAP Barbell. 

Don’t worry; the prices have gone up temporarily because of the high demand for home gym equipment during the pandemic. The prices should get back to their normal range in some time. If you want to buy them, make sure you compare the prices on Amazon and Academy because they are not always the same.


We are giving this a rating of 4.1 out of 5.0.

Wrap Up

CAP Barbell competition bumper plates deserve a better rating than this but the seller needs to bring the prices down to a level that matches their quality. If you get them at a justified price, go for them and you won’t be disappointed. 

That’s all we have for this review article. If you think you don’t need competition bumper plates, you could go with the budget bumper plates instead. They are affordable but not recommended for people who drop their barbells more often.
