![]() The knurl termination points on the bar are well done and they’re very pleasant to look at. I would love to see Fringe Sport lengthen this center piece to give the back a bit more surface to grip. ![]() Every one of my bars that has a center knurl measures between 4.5″-5″. The center knurl measures 4″ in length, which is actually pretty short. It’s interesting… I can think of several bars that have mountainous knurls – something commonly associated with aggressive bars – that are actually LESS aggressive than the Lone Star Power Bar. This spreads out the points which, much like the bed-of-nails comparison above, adds to the aggressive profile. Also of note is the Lone Star pit is wider than others (e.g. In my observation, this contributes to the overall aggression. Therefore, the edges surrounding the pit are more pronounced. When you look at the Grizzly bar in comparison to the Lone Star Bar, you can see that the pit is much deeper on the Lone Star. The more pressure, the more displacement. When you press a knurl bit against a blank piece of steel, it displaces the material to create the actual knurl. In the vast majority of applications, a bar’s knurl is actually pressed, it’s not cut. Knurling is basically the same.Īnother reason I suspect this bar is more aggressive is that the pit is pressed deeper during manufacturing. If you watch people do it, you’ll notice the nails are tightly packed – this distributes the pressure more effectively. Because of this, it doesn’t distribute the pressure around in the same manner, thereby leading to a more aggressive feeling bar. ![]() In looking at the Lone Star bar you can quickly see that the points-per-square-inch ratio is considerably less. In effect, it spreads the pressure around the surface more as compared to a bar with a smaller ratio. The Grizzly Bar has a very high points-per-square-inch ratio. Why is that? Well, the biggest reason is that the points-per-square-inch ratio is different. If you look at some other volcano-knurled bars, like the American Barbell Grizzly Bar for instance, they are indeed quite a bit less aggressive. Typically this is true, but this bar is proof that merely having a volcano knurl does NOT mean it can’t be really aggressive. It strikes a nice balance in the hand we’re told. It’s not mild, like a hill, but it’s also not sharp, like a mountain. Generally speaking, it’s a preferred profile. We hear a lot about volcano knurls when describing a barbell – the kind that’s pitted. You remember that high school cheerleading routine… Be Aggressive, Be-e aggressive, B-E-A-GG-R-E-SS-I-V-E… It offers consistent machining, powerlifting knurl marks, and a 4″ center knurl.įirst thing’s first: This bar is aggressive. The knurling on this bar is aggressive with a deep volcano pattern. I agree – you should absolutely have a 29mm bar, especially if you have intentions of ever competing in powerlifting.īUT, training with a 28.5mm bar can actually be quite useful as a change-of-pace bar. You’re probably thinking that you need a 29mm power bar. It feels nice in the hands with an aggressive knurl, it’s 100% made in the USA, it looks better aesthetically, and it performs nicely… if you don’t mind a 28.5mm power bar. The Lone Star Power Bar is a superior offering, in my opinion. I’ve owned the original Fringe Sport Power Bar since 2018. Looking at their full barbell lineup, I think they may have just added three new starters to the roster. Fringe Sport Lone Star Power Bar Ratingįringe Sport recently dropped the mic with their triple release of the new Lone Star Power Bar, the Longhorn Buffalo Bar, and the CeraColt Olympic Bar.
