Each bar has been manufactured from North American made steel. The Black Oxide International Bars are finished with a black Oxide coating & feature hard chrome split sleeves.
It is a strikingly attractive bar. The black oxide finish has an aggressive grip. York applied its signature "split sleeve" design to each bar which replaces the outmoded bolt and sleeve assembly.
The outer ends are on bushings instead of the bearings found on higher end bars but they turn freely enough. One side is a little rougher than the other but it is not noticeable when the bar is loaded. The bar is 51 (or 52) inches long between the collars which means you can use it with standard squat racks and cages, a big plus. The knurling is excellent, deep enough for a good grip but not so deep as to shred your palms. The 30 mm diameter has not been a problem for me so far but I do only powerlifting type movements not Olympic ones, YMMV. The ends are of necessity a little on the short side so anyone wanting to go really heavy will have a problem getting enough plates loaded, but I'll worry about that if and when I get that strong. This is an excellent buy and Fitness Giant had it a little cheaper (shipping included) than other sites I looked at.
