Its probably this bar: https://www.amazon.com/Sports-Troy-Barbell-Olympic-Chrome/dp/B00AJ1I7U0/ref=sr_1_2?s=sporting-goods&ie=UTF8&qid=1465521367&sr=1-2&keywords=troy+olympic+barbell
$80 used, no thanks.
Edit: I should clarify. I didn't truly mean this exact bar. What I meant was, the listed bar says Troy bar. Just because it has center knurling doesn't make it a "power bar". The bar looks like trash, and at $80 for a dirty Troy bar that at best retails for $200? Unless your market sucks ass that is not a good deal.
