I love the spin of this bar it is true to the hype. I love how smoothly it spins while obtaining my grip for first pull. The bar will roll into your grip smoothly. I especially feel the spin on the jerk as I can feel my hands/wrist turning over into position. I was disappointed with the knurling. The knurling is not very aggressive at all and the cuts on my bar were a little (maybe more then a little) sloppy. The center knurling lines are slanted and not on a crisp start and finish. Seems the machining process was not on point. The outer knurling also blend in and don't have a crisp sharp beginning. None of which affect the bar spin or performance but just looks sloppy for a $500 bar. Overall great bar performance. Sloppy on looks.
