Our award-winning flagship bar with built-in collars. The SlideLock™ technology makes for a safer, tidier and more user-friendly weight lifting experience. Tested for performance, The Allrounder is a highly durable and solid bar suitable for all uses.

The SlideLock and bar have been drop tested extensively in a drop-testing rig that simulates the varieties of 15.000 real life drops at heights of 1.6 m loaded with 320 kg of plates, as well as heights of 2.2 m with 90 kg. Not to mention the hydraulic press test that proved the Slidelock can endure a vertical pressure of 15.000kg, while staying perfectly intact.

Still don't trust it? The bar comes with a lifetime warranty. In the highly unlikely event that the SlideLock breaks, you get a new one free of charge.

The allrounder

See how it works

Lift, slide, lock


Watch it hold
a car

We hung a car at the end of the Allrounder 20 kg Olympic bar to see what happens. Our products get a fair share of scepticism from time to time, with people saying things like “That will be broken in about two heavy deadlifts” or “I wouldn’t trust it for a second”. And we get it, the SlideLock is small and doesn’t look like it could hold a lot.

But as they say; never judge a book by its cover. As it turns out, the SlideLock holds up to 15.000 kg in vertical pressure tests in a hydraulic press. Which equivalates to two elephants. Or a semi truck. Or a lot more than a car like this one!

A great new supplement to Eir trening.

The Gungnir Allrounder 20 has already become the favourite bar among our customers. It is easy to use, the quality seems very good and the built in collars is a great invention. The never ending search for the always missing collars is history.

I can really recommend Gungnir to everyone.

Like It But Don’t Love It

This is a good bar. It is my 2nd Gungnir Bar in the past 2 months (Curler). I like that bar quite a bit so I thought I’d change out my straight bar. The Slidelock System is brilliant for quick weight changes (Drop Sets). Swap weights with one hand while sliding the collar with the other makes it efficient and oddly just kind of fun. The craftsmanship is excellent.

I’ve had a few good workouts using the bar, and there are a few things that have stood out as being different than what I’m used to using. As stated this is a 28mm bar. If you are a weightlifter then you are good to go, but if you’ve been using 29-30mm power bars for 30 years then it may not be as comfortable as you are looking for.

The knurling is pretty passive. It’s not a deal breaker, but again if you are accustomed to a sharper knurl then you will notice the difference. The downside of the relatively passive knurl is the ability to feel the markings if you use them for setup. Easy to see them. More difficult to feel them.

For the Gungnir folks, packaging for shipment needs a bit of QC. Shipping across the world through various hands, the bar arrived on my driveway sticking partially out the end. Blame goes to the FedEx handlers but the ends could be sealed a bit better than packing tape to prevent this from happening. Didn’t notice any damage but I did end up catching a metal burr on 1st use. Didn’t feel it but noticed a small puncture wound during workout.

I wouldn’t hesitate to buy this bar…

Gungnir’s Allrounder - Going Beyond! (5-month review)

Gungnir’s Allrounder - Going Beyond! (5-month review)

My review of the Gungnir – Allrounder bar after purchasing back in July. Ordered on July 4th and received it on July 10th. Extremely fast shipping with great packaging from Gungnir especially want to highlight this since it is being shipped from Norway.

There’s a lot of videos online already talking about the crazy amounts of weight that the collars can hold and still being usable – the most crazy and ridiculous one being the bar holding a weight with a car. Here’s a link to check it out

Having this barbell since July on average I’ve done at least 50 drops minimum with this bar between deadlifts and cleans. (Honestly this is low-balling the number as have multiple people use this bar when people come over to workout)

Today on 11/26/22 after an amazing Thanksgiving with friends and family, we did our version of a Turkey Trot, however instead of running we did some lifting. We have dropped this collarless bar over 1000 times and not once have we had an issue.

My home-gym community favorite:

It has just become the “Go-to” bar in my home gym for both myself and everyone who comes over. It’s a little silly but people just got used to picking up this bar and lifting with it for every workout. When I asked my friends about it, the little small quality of life that comes with never worrying about collars is something you really…
