Overview

Synergee's Super Curl bar (model SF-SUPCURL-BLACK-CA) is a 47.2 inch EZ curl bar finished in black phosphate, built with 2 inch sleeves and bushings so it loads standard Olympic plates for curls, rows and tricep extensions.

At 20 lbs bar weight and a listed 400 lb max load, it's positioned as commercial grade rather than a light home gym accessory. The curved shaft angles more than a standard EZ curl bar, meant to keep wrists and elbows in a more natural position during arm and shoulder work, and each sleeve offers 6.25 inches of loadable length.

  • 47.2 inch bar with 28mm shaft diameter
  • 2 inch sleeves compatible with standard plates
  • Black phosphate finish with brass bushings
  • 6.25 inches of loadable sleeve length per side

Who it's for

Works for anyone with a home or commercial rack who already owns 2 inch Olympic plates and wants a dedicated curl bar rather than adapting a straight bar. Less necessary for someone with only bumper plates on a smaller sleeve diameter or very limited storage space, given this is a full length 47.2 inch bar.

Pros and cons

Pros
  • 2 inch sleeves load standard Olympic plates without adapters
  • Curved shaft angle aims to reduce wrist and elbow strain
  • 400 lb rated capacity
  • 6.25 inches of loadable sleeve length per side
Cons
  • At 47.2 inches and 20 lbs, it needs real rack or storage space

Performance notes

The curved shaft creates a wider angle than a typical EZ curl bar, meant to reduce wrist strain during bicep curls and tricep extensions by keeping the joints in a more neutral position through the lift. Bushings at the sleeves are built to spin under load rather than lock the plates in place.
