Absolutely, my CAP bar had metal pieces on the inside floating around. After fixing it up it doubled the spin and smoothness, and also gave me a chance to wipe off that ugly green sticker. The Troy bar was more of the same, I'm much happier with its performance than I was initially, the spin seemed rough and only lasted for about 12-14 seconds when tested (both sides). Now it seems much smoother and is going for 18-20 seconds on average when using a 45lb plate and several spins. I saw a video a long time ago where someone suggested doing this initial maintenance with every bar you buy, even if it's an Ivanko or Eleiko. I would just be nervous as hell breaking one of those down LOL
