It's built for lifters who want a grippy, skin-friendly knurl for high-volume training that's still precise and durable enough to compete on.\u003c\/p\u003e\n\u003ch3\u003eStainless Steel Powerlifting Barbell with KP1.0 Square Knurl\u003c\/h3\u003e\n\u003cp\u003ePart of the in-house design is the sleeve collar: an angled, faceted shape that reads as an Olympic torch from one side and a blade from the other. On the power bars it's kept slim — the narrowest sleeve collar in the range — while the weightlifting, hybrid, squat, and deadlift bars each get a wider version scaled to their own proportions.\u003c\/p\u003e\n\u003cp\u003eThe shaft is bare stainless steel with no plating at all. On coated bars, the knurling is cut first and a layer of chrome or nickel is then deposited on top, which softens and slightly rounds the sharpest edges of every knurl. Since nothing is plated onto this shaft, the knurling stays exactly as sharp as it was cut. This is the sharpest grip in the range while stainless steel's natural chromium-oxide layer still gives it excellent built-in corrosion resistance.\u003c\/p\u003e\n\u003cp\u003eThis bar uses a KP1.0 square knurl instead of the 1.2 mm diamond pattern on our other power bars — finer and shallower (0.3–0.4 mm cut depth), with a wider 140 mm center section. A square knurl cuts a grid of small, flat-topped ridges rather than sharp diamond points, so it spreads grip across more of your palm instead of concentrating it on widely spaced peaks. In practice, that means less skin irritation during high-volume sets while maintaining a secure grip for heavy singles. It is a practical choice for lifters who want to train with the same knurl they will use on the competition platform, so there is no sharper pattern to adjust to on meet day.\u003c\/p\u003e\n\u003ch3\u003e29 mm Power Bar for Squat, Bench Press and Deadlift\u003c\/h3\u003e\n\u003cp\u003eRotation comes from graphite-infused bronze bushings. A solid bronze sleeve bearing with graphite particles embedded directly into the metal, acting as a permanent, built-in lubricant that can't dry out, wash out, or need re-greasing; it lubricates itself for the working life of the bar. Bushings rotate more slowly and with greater resistance than bearings, producing a calmer, more controlled sleeve rotation. This helps prevent the loaded plates from swinging or over-rotating during squats and bench press, where faster sleeve spin can reduce stability.\u003c\/p\u003e\n\u003cp\u003eThe 29 mm shaft stays stable and predictable under heavy squats and bench presses while retaining enough flex to feel responsive in the hands. Its stiffness sits between the pronounced whip of the Deadlift Bar and the near-zero flex of the Squat Bar.\u003c\/p\u003e\n\u003cp\u003eEvery Riot bar uses the same clear identification system. Its name, weight and shaft diameter are laser-engraved on the inner face of the sleeve collar, keeping the specifications visible throughout the life of the bar whether it is hung, stacked or stored sleeve collar-first. The end cap repeats the key information at a glance: it is colour-coded by weight, blue for this 20 kg bar, and shows the weight directly on the cap. This makes it easy for anyone on the gym floor to select the correct bar for the relevant discipline without checking a separate label.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ccaption\u003eSpecifications\u003c\/caption\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpecification\u003c\/td\u003e\n\u003ctd\u003eDetails\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDesign\u003c\/td\u003e\n\u003ctd\u003eIn-house design\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct type\u003c\/td\u003e\n\u003ctd\u003eCalibrated competition\/training power bar (IPF-legal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShaft material\u003c\/td\u003e\n\u003ctd\u003eStainless steel (uncoated)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSleeve finish\u003c\/td\u003e\n\u003ctd\u003eHard chrome\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShaft diameter\u003c\/td\u003e\n\u003ctd\u003e29 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e220 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSleeve diameter\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e20 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight tolerance\u003c\/td\u003e\n\u003ctd\u003e±50 g (calibrated)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKnurling\u003c\/td\u003e\n\u003ctd\u003eKP1.0 square, 0.3–0.4 mm depth, 140 mm center width\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMarkings\u003c\/td\u003e\n\u003ctd\u003e81 cm (IPF)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRotation\u003c\/td\u003e\n\u003ctd\u003eGraphite-infused bronze bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax load recommendation\u003c\/td\u003e\n\u003ctd\u003e680 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnd caps\u003c\/td\u003e\n\u003ctd\u003eBlue (20 kg colour code)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs this bar IPF-legal?\u003c\/strong\u003e\u003cbr\u003eYes.

The end cap repeats the weight and is colour-coded blue for this 20 kg bar.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the sleeve collar look like that?\u003c\/strong\u003e\u003cbr\u003eIt's part of Riot's in-house design language: the angled, faceted sleeve collar is drawn to suggest both an Olympic torch and a double-edged sword. Sleeve collar width is slimmest on the power bars, mid-width on weightlifting and hybrid bars, and widest on squat and deadlift bars.\u003c\/p\u003e\n\u003ch3\u003ePowerlifting Barbell Finishes Compared\u003c\/h3\u003e\n\u003cp\u003eAll Riot Power Bar variants share the same core specifications: a weight of 20 kg, an overall length of 220 cm, a 29 mm shaft, 50 mm sleeves, 81 cm IPF markings and a recommended maximum load of 680 kg. Most variants also use the same sharp 1.2 mm diamond knurl with a 120 mm centre knurl. The variants differ in their finish, weight calibration, knurl pattern and approval for IPF competition.\u003c\/p\u003e\n\u003cp\u003eThe finish affects both surface protection and how directly the knurling is felt in the hands. Bare stainless steel has no plated layer, so the knurl retains the exact edge produced during machining and gives the sharpest feel in the range. Black chrome forms a thin, very hard coating that follows the machined profile closely. This preserves almost the same sharpness while adding a dark, wear-resistant surface. Black chrome is not included on the IPF's approved finish list, so these models are not legal for IPF competition.\u003c\/p\u003e\n\u003cp\u003eNickel is applied in a slightly thicker, softer layer, which reduces the sharpest edge of the knurl compared with black chrome. The finish is approved by the IPF, making nickel and stainless steel the two competition-legal options in the range. Hard chrome is used on the shaft of the Power-Chrome training bar and on the sleeves throughout the Riot range. It provides a durable surface for regular commercial gym use, but is not used for the calibrated or IPF-approved models.\u003c\/p\u003e\n\u003cdiv class=\"desktop-only-table\"\u003e\n\u003ctable\u003e\n\u003ccaption\u003eComparison Riot Bastard Power Bar variants (all 29 mm \/ IPF spec)\u003c\/caption\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd\u003eVariant\u003c\/td\u003e\n\u003ctd\u003eKnurling\u003c\/td\u003e\n\u003ctd\u003eShaft finish\u003c\/td\u003e\n\u003ctd\u003eSleeve finish\u003c\/td\u003e\n\u003ctd\u003eWeight tolerance\u003c\/td\u003e\n\u003ctd\u003eIPF legal\u003c\/td\u003e\n\u003ctd\u003eBest for\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibrated Stainless Steel (Competition)\u003c\/td\u003e\n\u003ctd\u003e1.2 mm diamond, 120 mm center\u003c\/td\u003e\n\u003ctd\u003eStainless steel (uncoated)\u003c\/td\u003e\n\u003ctd\u003eHard chrome\u003c\/td\u003e\n\u003ctd\u003e±50 g\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003ctd\u003eIPF competition, sharpest knurl feel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibrated Stainless Steel (Square Knurl)\u003c\/td\u003e\n\u003ctd\u003eKP1.0 square, 0.3–0.4 mm depth, 140 mm center\u003c\/td\u003e\n\u003ctd\u003eStainless steel (uncoated)\u003c\/td\u003e\n\u003ctd\u003eHard chrome\u003c\/td\u003e\n\u003ctd\u003e±50 g\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003ctd\u003eHigh-volume training and competition, grippy but skin-friendly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibrated Nickel\u003c\/td\u003e\n\u003ctd\u003e1.2 mm diamond, 120 mm center\u003c\/td\u003e\n\u003ctd\u003eNickel\u003c\/td\u003e\n\u003ctd\u003eNickel\u003c\/td\u003e\n\u003ctd\u003e±50 g\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003ctd\u003eIPF competition, smoother\/milder knurl feel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibrated Black Chrome\u003c\/td\u003e\n\u003ctd\u003e1.2 mm diamond, 120 mm center\u003c\/td\u003e\n\u003ctd\u003eBlack chrome\u003c\/td\u003e\n\u003ctd\u003eHard chrome\u003c\/td\u003e\n\u003ctd\u003e±50 g\u003c\/td\u003e\n\u003ctd\u003eNo (non-IPF competition)\u003c\/td\u003e\n\u003ctd\u003eNon-IPF federations wanting calibrated accuracy with a sharp, dark finish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChrome\u003c\/td\u003e\n\u003ctd\u003e1.2 mm diamond, 120 mm center\u003c\/td\u003e\n\u003ctd\u003eHard chrome\u003c\/td\u003e\n\u003ctd\u003eHard chrome\u003c\/td\u003e\n\u003ctd\u003e±1%\u003c\/td\u003e\n\u003ctd\u003eNo (training)\u003c\/td\u003e\n\u003ctd\u003eDaily training, high volume, durable and affordable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBlack Chrome\u003c\/td\u003e\n\u003ctd\u003e1.2 mm diamond, 120 mm center\u003c\/td\u003e\n\u003ctd\u003eBlack chrome\u003c\/td\u003e\n\u003ctd\u003eHard chrome\u003c\/td\u003e\n\u003ctd\u003e±1%\u003c\/td\u003e\n\u003ctd\u003eNo (training)\u003c\/td\u003e\n\u003ctd\u003eDaily training, dark aesthetic, near-stainless sharpness\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cstyle\u003e\n  thead td {\n    font-weight: bold;\n  }\n  table caption {\n    text-align: left;\n    font-weight: bold;\n    font-size: 1.17em;\n    margin-bottom: 0.5em;\n  }\n  @media (max-width: 767px) {\n  .desktop-only-table {\n    display: none !important;\n  }\n}\n\u003c\/style\u003e","brand":"Strength Shop","offers":[{"title":"Default Title","offer_id":57208428069129,"sku":"BAR-RIOT-POWER-STEEL-TRAINING","price":487.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0564\/6113\/1956\/files\/BAR-RIOT-POWER-STEEL-TRAINING_Shop-00_9ea90d4a-fb8b-4020-9c48-d0e0fe5c4ee0.jpg?v=1787681230","url":"https:\/\/strengthshop.eu\/en-nl\/products\/calibrated-riot-power-bar-st-steel-ipf-approved","provider":"Strength Shop","version":"1.0","type":"link"}
