The detail

190,000 PSI on a 15 kg bar is the point. Smaller bars are routinely specified down on the assumption they will be loaded lighter — PRX's own Olympic Elite drops to 180,000 PSI in its 15 kg version. This one does not, so the bar is not the limiting factor for anyone.

The 25 mm shaft is the real reason to buy a 15 kg bar, and it has little to do with the five kilos. Grip is what stops most pulls long before the back or legs do, and a shaft you cannot close your hand around costs reps that have nothing to do with strength. The same case applies to the REP Colorado 15 and the Titan women's bar.

No centre knurl at all is the correct call here. Centre knurl helps a low-bar squat and hurts everything else, and it is at its worst in a front-rack position. Olympic and power marks together keep the bar usable for both disciplines.

Medium knurl is right on a 25 mm shaft — less surface to hold means the texture does more of the work.

The 11.7-inch loadable sleeve is the honest limitation. That is about two and a half bumpers per side, and shorter than the Colorado 15's 12.4. If you load heavy, pair it with thin plates or machined iron.

At 79.5 inches the bar is seven inches shorter than standard, so check J-cup spacing — a rack set for an 86-inch bar will hold it close to the uprights.

Made in the USA is genuine and unusual in this category. The warranty covers manufacturer defects rather than a lifetime term, which is a step below the Olympic Elite.
