Men's Wonder Bar V2 20kg Barbell by Fringe Sport

When you're lifting, and in your zone, grinding out that last rep, do you think about the barbell? Do you even feel the barbell? Or does the barbell become a seamless extension of your body and movement? If you haven't had the pleasure of using such a well-crafted barbell, that's going to make you feel like you're gripping future forward cybersteel, then today your workouts have forever improved thanks to the best box bar out there- the Fringe Sport Wonder Bar V2.

We Built the 8th Wonder of the (Barbell) World for You

The Wonder Bar reigns as the nucleus of the barbell universe here at Fringe. We set out on a noble quest to design and build the best bar suited for commercial gyms, and make it available to you at a home gym price. We completed our hero's journey and now offering our reward to you delights us. This versatile bar will serve almost everyone well. You can set world records on this bar, and use it for most training. If you're a seasoned athlete or an affiliate owner, consider stepping up to the Bomba Bar V2 (made in America) or even our Fringe Sport Weightlifting Barbell. Here are a couple of Wonder Bar features to be aware of:

  • The 28mm shaft diameter is great for Olympic movements.
  • The needle bearing cartridges provide great spin, but may require oiling in time.
  • If you're new to lifting or building a home gym and need more info to learn what type of barbell works best for you, here's a helpful guide.

We have an informal state motto here in Texas- "come and take it." Not only do we want you to do this with the Wonder Bar V2, but we'd like to put our own spin on it. Fringe it, or forget it.

If You're Wondering...

Your home gym, might be in the garage. You don't want it to feel like an auto mechanic's shop. Do you reach for your barbell and mistake it for the handle of a car jack lift? Grab the Fringe Sport Wonder Bar V2 and you'll question whether it's a barbell, or if you've grown new arms like the T-1000 Terminator.

Ok, you're not a nanomorph, but after training with this barbell, it'll feel like it's matching your molecular structure and become your custom, workout mimic. The natural feel of the Wonder Bar V2 will lead you to workout singularity, and extra reps you don't even realize you're doing. Ready to transform your home workout venue from a Pep Boys to training to crush puny humans? Then read on.

The customer nicknamed "Black Magic" will slay the competition and be the wisest addition to your arsenal. Since the first version of the Wonder Bar V2 was introduced, Fringe Sport blacksmiths have spent many years heating up, hammering out and perfecting a far superior model in their top-secret forge.

Our anvils produced a barbell embodying the strength and grit of Texas better than a Clint Eastwood spaghetti western. The legend of the Wonder Bar V2 makes it an integral component of your home gym setup. As soon as you unbox it, and feel it in your hands, any lingering doubt as to why you chose your new centerpiece, will be lifted.

Fringe Fans Throw Our Weight Around

Wonder bar V2 fans agree. Jesse from Amazon says:

"Perfect! Ordered my barbell and it was shipped promptly. Received it in great packaging. I've been using it for weeks now with no issues. Feels sturdy and well-constructed. Exactly what I was hoping for."

After making the Wonder bar V2 the focal point of your home gym, you might blush after realizing what a deal you've found. The value of the quality for the price aside, our spotters here at Fringe Sport headquarters got you covered when it comes to customer service, that no one else can match.

Our Facebook reviews speak for themselves:

Shane Nelson says:

"Quality equipment. Great price. And, hands down, unbeatable customer service! What more could you ask for? This spring we decided to build a garage gym and purchased the majority of our equipment at FringeSport and will continue to do so as we add equipment in the future. I would recommend them to anyone in the market."

Tony Arkitect says:

"Fringesport has the best customer service, and I don't mean the best in the fitness industry, I mean the best in any industry. Legendary. Keep up the good work guys."

Bushing vs Bearing

Our 20kg Wonder Bar comes in a bronze bushing and needle bearing cartridges. Both bars are excellent for lifting and provide spin.

  • Needle bearing cartridges in the collars provide a little more spin than a bushing barbell.
  • Bearing barbells have smoother rotation and cost a little more than a bushing.
  • Bushing barbells are common for heavy or slower lifts, such as powerlifting.
  • Bearing barbells are common for faster lifts, such as Olympic lifts.
  • Bushing barbells are easier to maintain than their needle bearing counterparts, easy to disassemble, clean and reassemble, making them more durable.
