 Women's Wonder Bar 15kg Olympic 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.

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 (made in America) or even our Fringe Sport Weightlifting Barbell. Here are a couple of Wonder Bar features to be aware of:

  • The 25mm 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, 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 and you'll question whether it's a barbell, or if you've armed yourself like Sarah Connor and have the steely resolve to fend off Terminators sent to destroy you.

We can't guarantee you'll prevent an A.I. induced nuclear war with this barbell, but you'll be kicking butt and getting ripped like Sarah Connor for sure. The natural feel of the Wonder Bar will turn your workouts heroic, and provide 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 Skynet? 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 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 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 fans agree. Isquared99 from Amazon says:

Why Lift with a Wonder Bar Women's Olympic 15kg Barbell

Female powerlifters train and lift on "man" bars. So why do female Olympic lifters and WODers need a different bar, one that weighs 5kg less?

Simple. It's all about the grip, and the transition of the bar from the ground to overhead. Women's hands tend to be smaller than men's, and a "women's" bar weighs 15kg (33 lb) and features a 25mm shaft diameter vs. the "normal" 20kg and 28-32mm shaft.

The thinner shaft allows for a better grip and better form in transition and in overhead positions.

Can men use a 15kg bar? Sure, but most don't. 20kg bars are considered the standard in the WOD, Oly, powerlifting, and bodybuilding communities. But hey, weight is weight, and mean ol' Mr. Gravity doesn't care. And- we did recently hear about some guys doing Zercher squats, Zercher carries, and Zercher good mornings with a 15kg bar- since the smaller shaft makes the exercise more uncomfortable.


The Wonder Bar comes in a bushing version or bearing cartridges version. Except for that, the specs for both are the same.

  • Also available in a Men's Wonder Bar 20kg.

Bushing vs Bearing

  • Our 15kg 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.

    The 15KG Wonder Bar ist Wunderbar Also

    Let me say that this 15 KG women's Olympic bar will make you rethink your decision to not buy imported barbells--if that decision was based on the preconceived notion that "imported" means lower quality. This thing is a beast and extremely well designed. I usually prefer a much more aggressive and sharp knurling, but I am starting to dig the sandpaper-like grip of this bar for everyday training. And the four needle bearing cartridges per sleeve make this the hands-down better choice over some more cheaply made USA bars at this same price point. See my full blog post about it here:

    This bar was a great value, but I’m impressed with the quality. It is everything I was looking for in a women’s barbell.

    Love this Bar!

    Great spin and not too aggressive knurling for those WODs. Very attractive price point when bought during the sale.
