Super EZ Curl

Name: Super EZ Curl
Brand: Synergee
Rating: 4.42 (4 reviews)

The Synergee Super Curl Bar is a 20 lb, 28mm specialty curl bar with noticeably steeper bend angles than a standard EZ curl bar, positioning the wrists in a more stacked, neutral-leaning grip aimed at biceps, triceps (skull crushers), hammer curls, and rows. It runs a 400 lb weight capacity on bushing (not needle-bearing) 2” sleeves with 6.25” of loadable sleeve length per side, and ships in chrome, black phosphate, black phosphate/chrome, or red Cerakote finishes with a 3-year warranty. Synergee also sells a separate, less-aggressively-bent EZ Curl Bar – reviewers consistently flag this Super Curl variant’s short sleeves and lack of center knurling as its main limitations, trading some pure bicep isolation for its more joint-friendly tricep and hammer-grip angles.

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.

Synergee’s Super Curl Bar draws consistent praise for doing exactly what a specialty curl bar should: its steep bend angles earned it “Best Super Curl Bar” picks from both Garage Gym Lab and King of the Gym, and a year-plus owner review calls it “a super quality bar” with smooth, solid-feeling bushing rotation. Functionality is the standout – the aggressive camber opens up hammer curls, triceps work, and a more joint-friendly wrist position that a standard EZ curl bar can’t match. The weakest dimension is build quality: every editorial source flags the short 6.25” loadable sleeves and missing center knurl, Garage Gym Reviews considered it and passed, and one GymRadar owner reported the finish offering little rust protection.

+Functionality: steep bend angles enable near-neutral hammer-grip curls, triceps skull crushers, and a wrist-friendly angle a standard EZ curl bar can't match (King of the Gym, Garage Gym Lab, YouTube: Nick DiLeo)
+Build quality: brass bushings and chrome sleeves spin smoothly with little play -- "feels super solid" (YouTube: Nick DiLeo)
+Value: aggressive-enough knurling and multiple finish options at roughly $85, with GymRadar owners rating value 4.75/5 (GymRadar)
+Versatility: four finish options (chrome, black phosphate, red Cerakote) and standard 2" sleeves compatible with existing plates (Synergee product page, Living.Fit)

−Build quality: short 6.25" loadable sleeve length limits how much weight can be loaded per side (King of the Gym, Garage Gym Lab)
−Build quality: no center knurling reduces grip options along the inner camber (Garage Gym Lab, King of the Gym)
−Durability: one GymRadar reviewer found the finish "didn't offer much protection to rust" (GymRadar: Basement Brandon)
−Functionality: Garage Gym Reviews considered it for their curl-bar roundup but passed, saying they "didn't like this curl bar enough to include it" despite the sub-$100 price (Garage Gym Reviews)
