Absolutely amazing bar. Very whippy, if you're aggressive enough you can even feel it at oscillate at 60kg, but not so much so that its like a limp noodle, you can very much feel how sturdy it is once you start throwing more weights on there and the spin is amazing, goes for days! The knurling is very aggressive but honestly i wouldn't have it any other way. The only other bearing bar I've lifted on before was with an American bearing 20kg barbell, but the vulcan standard is miles beyond that. Best money I've spent on my home gym so far. Would definitely love to get more barbells in the future from vulcan!
