The Hybrid Bar

ATX® Black Mamba is very similar in regards to specification to ATX® Power Bar, the only difference would be an all-black oxide finish which in my opinion offers a meaner look.

Black Mamba is made of very strong and elastic spring steel. It has a massive 206,000 PSI (Tested!) meaning you will need quite a few plates to break it. Barbells under 190,000 PSI tend to bend over time from continuous use, while barbells over 190,000 PSI will remain straight even after years of lifting.

This bar offers dual markings (powerlifting and weightlifting) and no central knurling. Bars with no centre knurling won’t scrape your chest when performing Olympic lifts.

Weight Load Capacity

The weight load capacity varies between exercises due to the relevant load support of the different exercises. Squats are the lowest at 500kg because the load is only supported in the centre of the bar by your shoulders. Conversely, when you bench press your hands are spaced wider than the other lifts. This means there is less strain on the bar.

Regardless these capacities will not be an issue. The person that squats more than 500kgs will no doubt have back wider than the average bench press grip.
