Why your gym needs
built-in collars

There are many reasons to choose a Gungnir bar for your gym. The built-in collars add a whole array of benefits, without weakening the bar itself or affecting functionality or performance. No more disposable clips lying around, breaking, disappearing, bending, and no more hassle putting them on and taking them off.


People love a clean and tidy gym. The SlideLock being built in to the bar itself means you can keep your gym tidier with no more clips and collars lying around. That means no more picking them up, stepping on them or having them clutter up the place. 

The Allrounder - 20kg Olympic barbell - a bar with built-in collars. Tested for performance - Lifetime warranty. Seriously efficient workouts. Get your work done without wasting time fumbling with clips.


SlideLocks make for a safer gym experience, thanks to its great accessibility. Users choose to utilize the SlideLock more frequently than regular collars. Keeping the user and their surroundings safe.

More user-friendly

Provides the user with the most efficient and user friendly locking mechanism on the market. It has never been easier or more addictive to secure weights. With only two fingers, it's done. Lift, Slide, Lock. 

Design that stands out in a sea of regular bars

The Allrounder has been awarded with the 2021 Red Dot design award, Garage Gym Reviews' most innovative barbell 2022, and the prestigious FIBO Innovation & Trend Award 2022.

Durable and reliable

The built-in collars or SlideLocks have been tested to along with the bar 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 a hydraulic press test that proved the Slidelock can endure a direct vertical pressure of 15.000kg, while staying perfectly intact.

Seriously efficient workouts

Optimize workouts with faster supersets, dropsets and light-to-heavy exercises. The weight plates transition on and off faster, and neither the weights or SlideLock will budge while lifting. Giving the lifter efficiency and peace of mind to focus on the lifting. The SlideLock mechanism promotes great user experiences which in turn create better workouts. 

One less thing to worry about

You know how most of your clips and collars get bent, broken, or just go missing? Everytime something happens to them, you need to replace them. Built-in collars don't go anywhere, saving you both time and money. Giving you the peace of mind to focus on other important stuff - like running a gym.

Modern and sleek design

The 100-year old barbell has finally evolved. Award winning design made to be intuitive, functional and solid. It's a design meant to inspire users to be active. We don’t just want it to be a great workout tool, we want it to create such a good experience that makes the user want to come back and use it time, and time again. The way we achieve this is by creating a feel, a sound and a trust in a product and mechanism that simply becomes a joy to use.

And disposable collars aren't free

But we don't need to tell you that. Clips and collars are unreliable. It's only a matter of time before you need to buy new ones, and that cost adds up over the years. Having built-in collars erases that from the equasion, so you don't have to worry about replacing collars on every bar in your gym. Ever.

"One of the best barbells on the market. We have had this bar for 6 months now and don't see any marks or have had any issues with it. Loved it from the beginning. Comfortable knurling for normal lifting. Ideal for CrossFit, home gyms, globo gyms etc. Thanks guys and keep kicking ass on the productside of the training industry. We need Gungnir of Norway!"

"The Allrounder is an excellent bar and just a solid product. It's really easy to use. I was actually surprised at how efficient it was. I work at a PT/client facility where no members train on their own - only with a personal trainer or physical therapist. For about 6 months we've been using the bar, and now there's no going back for me. This is the real deal!"

"From day one I noticed a tidier gym. The feedback from the members has been amazing. They would never go back to old school barbells."

Stories from gym owners & staff
“The kind of bar you want to keep to yourself to get an edge on the competition. I’ve been in the business since the 80’s and i’ve always been annoyed by clips and collars. They break all the time and they disappear. The first thing I noticed when we took in the bars is that it helped us increase our professionality in terms of decreased clutter and increased safety.”
— Geir Arne Bjune, Owner of Spenst Lillehammer & Arena
