It’s cutting edge SlideLock™ technology makes for a faster and simpler weight plate transition with no need for additional clips, collars or clamps. Systematically drop tested for maximum strength and performance, the Allrounder is a highly durable and solid bar, suitable for all uses.

Made with a 216,000 PSI tensile strength shaft coated in hard chrome, dual knurl marks and mild center knurling. The quality bronze bushing sleeves make for a reliable spin, and the snap ring design maintains optimal stability throughout any type of usage, from basic home gym workouts to heavier garage gym workouts and high intensity Crossfit workouts.

Take a peek at what's inside

The Allrounder

What exactly is inside The Allrounder bar?

The design of the bar is no coincidence. We have worked day and night for the last three years and gone through countless iterations and failures to end up with the design we have today. Through extensive tests both in gyms and in drop testing jigs, we have experimented with dozens of different materials for the SlideLocks, shaft finishes, sleeve coatings and steel variations. Not to mention going through the incredibly difficult process of finding the right sub-suppliers for the different custom parts.

All of this to develop what has become the extremely solid and long-lasting solution that we are proud to present to you; the weightlifter, the crossfitter, the garagegymmer, or even the hobby-lifter. Here is a summary of the main components that make this bar special.

Game changing design

Built for excellence

Machined sleeves
Along with the Slidelock, the sleeves on The Allrounder are our not-so-secret sauce. What is perhaps more secret is the material we are using. The steel is a carefully selected high-strength steel that is both tough and ductile all at once, allowing the grooves to be strong enough not to chip off when subjected to high impact. The high-end steel has been machined by advanced state-of-the-art CNC-machines that along with a skilled operator gives a high precision sleeve with a tight fit for maximum resistance against slamming and wear. We have coated our sleeves with chemically applied nickel, this coating is special in its hardness and adhesion properties, and yields an even coat thickness on the sleeves that will last for a long period of time, even when it gets worn.
The SlideLock
Our SlideLock is made of grade 5 titanium. This is an incredibly strong and tough titanium often used in aerospace and racecars. A powerful neodymium magnet in the center helps it stay in place even when subjected to drops and slams. We tested the locks extensively in a drop-testing machine that simulates the varieties of thousands of real life drops. In these tests, we dropped the bar at heights of 1.6m loaded with 320kg of plates, and at 2.2m with 90kg. In addition, the lock’s tooth strength was tested in a hydraulic press where the lock endured a vertical pressure of up to 15.000kg, while staying perfectly intact. 
The shaft
The material we have selected for the shaft is a high-quality steel with a load capacity of more than 650kg and a tensile strength of 216k psi. The shaft is coated in Sweden with real hard chrome, which is often used for high quality pistons in the oil and gas industry. Hard chrome is well known for its excellent abrasion resistance due to the extremely high hardness and excellent corrosion resistance. The whip of the bar is like all other bars with the same diameter and plate setup. Meaning if you are used to a 28mm grip, The Allrounder will give you very close to the same whip.

Built with precision

The knurl
The knurl has been carefully balanced to fit both high rep workouts and heavy lifting. The center knurl has been made a bit milder so that squats or cleans still are doable. To give an enhanced micro-level grip, the hard chrome has been made with a satin finish, giving a completely unique almost cool blue gray look to the shaft. The combination of the medium knurl and micro-roughness from the finish has been described by many professional athletes as giving a “good grip that gives the feeling of being already chalked up”.
We have given alot of thought into the selection of The Allrounder’s bearing system. We wanted to make a bar that requires little maintenance while also having a long lifetime. For that, a bronze high-quality bushing was the way to go. Our wrapped bronze bushings also contain diamond shaped pockets that we fill with grease. The pockets act as reservoirs to progressively release lubricant during use. Allowing the maintenance needs to come with longer intervals and at the same time lowering the start-friction in a lift while also giving a smooth stop, which is critical for weightlifting.
There is grease, and there is proper grease. After lots of testing, we found that the best one for The Allrounder was the MoS2. This particular type is a combination of dry and wet lubrication. The MoS2 particles act as a dry micro barrier on top of the metals with low friction while the wet part of the grease allows for an even distribution and hold in the bushing pockets. The grease is very viscous (sticky) which makes sure that it stays in place for a long time. This, however,  affects the sustainability of the spin without having any effect on performance or in use.

  1. Fredrik Pedersen

    I was one of the lucky first who already got the chance to try out The Allrounder. I’m usually doing a combination of weightlifting and powerlifting in my garage, and the barbell itself has a good grip and spin for both uses. The locking mechanism is smoother than you can imagine. Simple and easy to use but at the same time rock solid. Great product!

    The allround bar was left to try out at my box and it worked really well! tried it aptly allround with some barbell cycling both light weight and some heavyish. Locks worked well and the plates didn`t slide at all! Besides from the bar being comfortabel to work with I like the fact that there are no additional locks needed, no tightning between sets, no running around looking for locks as the 10 second countdown has started on the wod.

    The allrounder works really well and the slide lock is so much easier to use than the collar! Genius!

    Allrounder stangen er helt fantastisk med det innovative låsemekanismen. Slipper å tenke på de “klypene” som løse deler. Her er det bare å smelle på vektplater og dunke på! Fantastisk produkt, koster noe men er en kvalitetstang man kan ha (og avskrive) i lengden. 🙂

    I’m lucky (and unlucky) enough to have tried The Allrounder multiple times now, and has definitely ruined other barbells for me.
    What differentiates todays cheap barbells from the expensive ones is often a series of incremental improvements that is – let’s face it – in many cases only recognisable to the most elite lifters. To me, an amateur/intermediate lifter, The Allrounder offers the quality of a top bar, but more importantly, something truly new and exciting with the Slidelock.

    Received my bar today and it truly is a thing of beauty! The knurling on the bar is spot on perfect!! The finish is a satin and it’s so damn nice looking I don’t wanna bounce it off the bench arms.. but the fellas at GUNGNIR just emailed me back and gave me a direct order to give it no mercy !! I must say it’s so worth the wait and money! I CANNOT WAIT for a set of 15 inch Olympic dumbells with this collar system!!!!! Very very pleased from the USA! Chris

    This is not a gimmick, this is innovation! The sliding collar mechanism works flawlessly, is simple, and the whole barbell is exceptionally well made. I won’t be looking back, that’s for sure.

    As one of the first gyms to recieve this barbell, I can tell you that it’s definitely one you should check out and consider buying.
    This is not just a premium barbell with a functioning locking-mechanism. It gives your members increased safety, ease of use and helps keep the gym tidy with less springs and collars laying around!

    The Gungnir Allrounder bar is a beautiful, exceptionally crafted, high quality barbell. Everything from the sleeve fitment to the shaft, the ribbed sleeve/slide lock application, the matte chrome and nickel coating, as well as the clean knurl are very quality. In my opinion, the whip is absolutely perfect for a multi-use all around bar. It’s not as whippy as a pure weightlifting bar or as stiff as a power bar. To me, it’s just right!

    As a CrossFit athlete, i tend to train various movements in a very limited times. Olympic lifting, strength training and metcons workouts needs me to focus on the movements not on worrying if the weight on the barbell will get loose from grips or takes more time to remove the grip and add extra weight.
    With this barbell i don’t worry about my plates gets loose in a metcon nor wasting time and focus on lift to add or reduce weight. I did test the barbell in heavy snatching, overhead training, deadlifting and stability work. Overall it is a very handy barbell, stable, strong and durable. Recommended for athletes. I will continue testing the barbell and see how it behaves with more time and more training. More details to come

    Been 1 month with a continuous usage of ” The Allrounder Gungnir 20kgs barbell” with more than 10 hours per week of usage. Very stable the grips are holding no matter if the drop was from the overhead or clean or a deadlift. Very fast transitions in workouts. Loving it ! Must say go easy on cleaning it with alcohol the barbell doesn’t like it. Highly recommended
