Bumper plates

Hi everyone,

I am going, finally, to buy a decent barbell and some bumper plates, so I can workout at home .

I am not from US, I am from Portugal, Europe. I have a dilemma, in my country we already have some bumper plates with good prices, I have tried some of them in my box and I did some comparison by myself between one type of bumper plates that I can buy in my country and rogue bumpers plates and they looked very similar, but I would like to ear your opinion.

Both of the bumpers plates that I did test were made in China, the "national ones" and rogue, because of that one question raised on my mind, should I go for rogue echo bumper plates or go for the "national ones", because both of them are made in China? What do you think?

Of course, national ones are cheaper. I will save 115€ on 150kg set.

Cheers!

Re: Bumper plates

There are a number of variables to consider when purchasing Bumper Plates. The first thing I noticed is I couldn't find any detailed information on either of the National plate types. Unlike the Rogue site.

Things I want to know before I buy

Weight
- Range of weights offered
- Plate Weight Precision
Size
- Bore hole diameter
- Plate Diameter
Rubber
- Type used
- SHa rating (Bounce vs Thud)
Bore Hole
- Type (Collar or Sleeve)
- Material (Copper, Zinc, etc)
Others
- Bur Edge
- Plate Width
- Colour

Important things to think about
- You really don't want a weight precision any more than 10g, some have a 250g possible variation, and this can add up to a pretty screwed up bar weight pretty quickly
- Obviously make sure the plates are regulation 450mm diameter, not all are. You may find the high temps are 444.5
- Bounce vs thud. High density = greater bar control on exit, but a much greater thud noise. For newbies or in a confined space the large bounce can get interesting, but the thud can also be an issue.
- Collars should be fine for you vs sleeves
- However Collar material quality matters, when a plate goes it goes because of the collar getting damaged and spinning or coming out, yet the price difference between high quality and low quality collars isn’t much. Also a sunk collar vs a flush collar will again ensure greater longevity....they also tend to stack nicer.
- As above, Bore whole size: the difference between 50.4mm and 50.5mm is surprising, the tighter the fit better for longevity for the plate and the bar, and the better the lift feels.

Lastly, some preferences....
- The Crumb Rubber might smell....check it out
- Colour matters, I hate coloured collared types they start looking tacky pretty quickly, but you want some way to tell weight difference quickly, more than just raised black letters....This is less important if it’s just you, but in a class situation....
- Do you want an edge on the plate, much easier to pick up of the ground
- Be careful of the high temps they are very low SHa so they are very thick (wide) and you'll be surprised how quickly your running out of room on your bar for your deadlift. And have to purchase thin iron 20kg to fix it. Not the biggest issue but just take note.

E.G.
Standard Oly Bar = 390mm clearance on bar sleeve
Hitemps on 25-20-15-5 + Iron plates on 2.5 - 1.25 - 0.5 = 367mm
Leaving only 23mm clearance for collars
This makes your max weight on your bar with hitemps 158.5 kg
And then you're investing in a 20kg iron plate to go any higher

Assuming you’re doing around 3 lifts per week, rotating thru the standard lifts DL-BS-BP-SP-PC etc
From a first time lifter to 160kg deadlift shouldn't take a male longer than 18 months
If it's taking longer there is something seriously wrong with your program.
So basically hi temps become limiting after 18 months

Hope this helps, questions welcome

Sean

Thanks a lot for your clear answer. I just ordered rogue echo bumper plates, it was just more 100€ than the national ones, and it will probably last longer and save money in the future.

I already have a good bar and iron plates for powerlifting stuff, this bumpers will be only for oly, since I am not at klokov level 160kg won´t be a problem on my life time eheheh

Cheers!

Re: Bumper plates

Hi everyone,

my rogue echo bumper plates arrived today, but one of them has a kind of defect in the insert. I don´t know if I should return it or not, because I don´t know if it is reason to care about..

Here are some pictures:

https://postimg.org/image/5vt297hlz/

This is one of the sides of the bumper, the other one is perfect.
It may seem that the insert is not secured but I tried to move it and it is secured.

What do you think?

Thanks!

Re: Bumper plates

hard to tell from the picks,
But am I seeing the coating of the collar has come off?

Definately return it.
Basically when a buymper plate goes, it goes becuase of the collar.

Is it better to return, right?

Cheers!

Re: Bumper plates

Hey, you paid full price for them. And rouge is really good about this kinda stuff.
Why shouldnt you get 100% quality for what you paid for.

It may not be an issue, or it may become an issue down the line.

If it was me I'd ask for a replacement. Again Rouge is really good about this kinda thing.
