N-Gage Grips

N-Gage Grips were designed to fit on olympic-style barbells that are 28mm to 32mm in diameter.

This means they have a 28mm internal bore diameter, and when attached to a true Olympic barbell - which is 28mm in diameter - there is no gap at the grip opening.

But all olympic-style bars aren't created equal.  True Olympic competition bars are 28mm, and Power lifting bars - or power bars - are typically 28.5-29mm. 

Olympic bars and power bars make up the vast majority of barbells in commercial and home gyms used for upper body lifts. N-Gage Grips fit perfectly on both.

Squat bars are another type of olympic-style barbell that you'll find a commercial gyms. They are thicker in diameter to help make them more rigid and have less flex.  These are usually 30-32mm+ and sometimes as thick as almost 34mm. 

Of course, the larger the bar diameter, the larger the gap at the grip opening.  So if your gym has a squat bar and you attach N-Gage Grips to it, you might think the grips don't fit your bar, but there's nothing wrong with a small gap at the grip opening.  Is it as perfect as we'd like it to be? no... but the grips will still work great on squat bars when used correctly.

So what about other equipment you might want to try N-Gage Grips on?

• Fixed weight barbells? Yes. nearly all fixed weight barbells are about 28-32 mm in diameter, so N-Gage Grips work great.
• Dumbbells? Most. The vast majority of dumbbells have the same range of handle diameter as barbells (28mm to 32mm). Of course the thicker the handle, the larger the grip opening gap - just like barbells. There is a ton of variation in dumbbell design, so N-Gage Grips won't fit on the contoured, beveled, or super thick handled dumbbells. Just remember, the closer the handle size and shape is to an olympic bar, the better the fit will be.
• Smith Machines? Most. Smith machines typically have 28-32mm bar diameters, so N-Gage Grips fit great. But sometimes they can be as thick as 36mm, so the gap at the grip opening will be pretty wide on those.
• Standard Barbells? No. These have a 1" weight sleeve that was usually threaded and unfortunately also a 1" bar diameter. The internal bore of N-Gage Grips are too wide for them to fit and be used safely. 
• Women's Olympic Bars? No. They are 25mm (or about 1") in diameter as well, so N-Gage Grips won't work on women's bars.
• Cable attachments? Some. cable attachments are 28-30 mm in diameter - most of these seem to be made out of aluminum -, but a lot of the older attachments out there are made of steel and are closer to 25mm in diameter. The grips won't work on the skinnier attachments since the interior diameter of the grips is 28mm. The grips work great with Tricep ropes thought.
• Pull Up Bars & Dip Bars/Stations? Some. Most dip stations have pretty thick handles - 1.5 inches or bigger, So N-Gage Grips won't fit great on those. But some out there have 28-34 mm diamater handles, and will work just fine with the grips. so just compare the handle to a barbell and see if it's close.
• Weight Machines? Some. Nearly all weight machines have pretty thick handles. usually 34mm or bigger. But because weight machines require less control, the larger gap at the grip opening won't matter quite as much. If you like how they feel on the machine and you can perform the lift safely, go for it!

So in a nutshell, N-Gage Grips were designed to fit olympic-style bars that are 28 - 32mm in diameter. The more any other piece of equipment resembles the size and shape of these bars, the better N-Gage Grips will fit.

Yes. As long as they are used correctly and responsibly.

There are always risks when lifting weight (with or without any sort of barbell attachment), so anyone lifting weight over their body should always use caution.

Obviously, N-Gage Grips are going to have limitations.  Benching 600 lbs with N-Gage Grips is not a good idea.  Benching 400 lbs would be pushing their limits too, but their performance is totally dependent on how much grip force you can apply to keep them glued to the bar throughout the entire movement. 

As we developed and designed the grips, how did we make sure N-Gage Grips were actually going to be safe to use? There are really three parts to this:

1. We made the grip opening run parallel to the grip itself rather than to the bar.  This means the grip wraps around more of the bar and therefore is much less likely to slip off somehow. 
2. We made each grips mirror images of each other rather than exact copies.  This means the grips can be set up so the angle is the same for both hands but the grip opening can face the same way too - which allows the weight of the bar to rest on the solid section of both grips. This ensures the bar doesn't fall through the grip opening somehow when you're using them.
3. But... the most important feature of N-Gage Grips that makes them safe to use is... our high quality, industrial-strength natural rubber material.  We tested dozens - maybe even more than a hundred materials through the years and have chosen the most safe, most non-slip, and most durable material we tested. Once you get your hands on it and get it on your bar, you'll understand. 

What makes this material so impressive is how it effectively becomes glued to the bar as soon as you apply some reasonable grip force.  With no grip force, the grips slide fairly easily to where you want them, but as soon as you really grip the grips, they don't move. 

This is why it's so important to use a very firm and forceful grip throughout the entire movement when you're using N-Gage Grips for any lift that places weight over your body like bench press.

No. Not yet.

We plan to open up international distribution in Canada, Mexico, Europe, and Australia in 2026.

In the meantime, try services like MyUS.com to get your hands on a set of N-Gage Grips if you live outside the United States.

Not yet. But soon.

We have several products in early stages of development that will compliment N-Gage Grips. We will be launching these products soon under the brand "New Growth Fitness".

At New Growth Fitness, we are focused developing unique and functional American-made strength training accessories to help you get the most out of your workouts.
