2" Knurled Axle

Name: 2" Knurled Axle
Brand: Black Widow Training Gear
Rating: 4.75 (4 reviews)

Black Widow Training Gear’s 2” Knurled Axle is an 84” non-rotating axle bar built for deadlifts, squats, pressing, and strongman work, adding a thick-grip challenge on top of standard barbell movements. It’s finished in a black textured powder coat and knurled with a center mark and knurling positioned 24” on-center from each side (6.5” toward the middle, 10” toward the outside), a pattern reviewers say sits closer to center than a typical axle – useful for lifters who bench at a narrower, shoulder-friendly width. Four independent GymRadar reviewers rate it 4.75/5 overall, consistently praising the knurling as aggressive and sharp (one called it sharper than a Gorilla Strength axle) and the powder coat finish as standout even against axles from other manufacturers, including use at Arnold Weekend 2025 competition. The main ownership caveat, raised by more than one reviewer: like most axles, its thick 2” shaft doesn’t accept standard Olympic collars, so budget for axle-specific collars separately.

What is a Barbell?

What a barbell is

The barbell is the center of a strength gym — the bar you squat, press, deadlift, and clean with. A men’s Olympic bar is 20 kg (44 lb) and 7.2 ft long (15 kg / 6.5 ft for women). The specs that matter: knurl (the grip texture — aggressive for pulls, milder for high-rep work), shaft diameter (28–29 mm for barbell lifts), sleeve rotation (bushings are fine for slow lifts; bearings spin fast for the Olympic lifts), tensile strength (~190k+ PSI resists bending), and coating (bare steel grips best but rusts; stainless and Cerakote trade grip for corrosion resistance).

Which one to buy

For general lifting, a multipurpose bar (28–28.5mm shaft, dual knurl marks, no center knurl) does squats, bench, deadlifts, and the occasional clean off one bar — this is the right first barbell for most home gyms. Choose a dedicated power bar (29mm, stiffer, aggressive center-knurl grip) only once you know you’re training squat/bench/deadlift specifically and want the stiffest, grippiest tool for that job. A dedicated Olympic weightlifting bar (needle bearings, more whip) is worth it only if you clean, snatch, or jerk regularly.

Beyond your main bar, specialty bars solve specific problems rather than replacing it: a safety squat bar shifts load off sore shoulders, a trap/hex bar takes stress off a cranky lower back on pulls, and a curl bar’s camber reduces wrist strain on isolation work. Add them once you know which problem you actually have.

4.75/5

4 reviews

A well-regarded knurled axle bar: four independent GymRadar reviewers rate it 4.75/5 overall, consistently calling out aggressive, sharp knurling and a standout black powder coat. Build quality is the strongest dimension — reviewers who’ve used other manufacturers’ axles single this one out for finish quality and knurl execution, with one noting it beat a Gorilla Strength axle for sharpness. Versatility is the weak point: it’s a specialty axle (no standard collar fit, non-rotating ends), squarely aimed at strongman/powerlifting grip work rather than general use, and coverage is still thin — 4 reviews plus manufacturer-page testimonials, no dedicated editorial review found.

+Build quality: powder coat and knurl execution called out as top-tier by reviewers who own axles from other brands (GymRadar)
+Functionality: aggressive, sharp knurling gives a secure grip on axle cleans, deadlifts, and presses (GymRadar)
+Build quality: used at a national-level strongman competition (Arnold Weekend) without issue (GymRadar)
+Value: reviewer called it well-priced at $225 for a knurled axle (GymRadar)

−Versatility: non-rotating, thick 2" shaft means most standard Olympic collars won't fit — budget for axle-specific collars (GymRadar)
−Durability: little long-term durability data yet — reviews are all within roughly a year of purchase (GymRadar)
−Value: no independent editorial review found (Garage Gym Reviews, Garage Gym Lab, etc.) — signal is limited to 4 GymRadar reviews and the manufacturer's own on-site testimonials
