Overview
A 7-foot Olympic barbell rated to a 1,200 lb load capacity, with volcano knurling for grip, bronze bushing sleeves for rotation and a phosphate finish over 120,000 PSI steel.
Bushing sleeves rather than needle bearings handle the bar's rotation, trading some spin speed for a simpler build that still smooths out wrist and forearm stress during presses and cleans. The 2-inch Olympic sleeves fit standard plates and most racks or benches, and reviewers repeatedly compare its feel favorably against bars costing two to three times as much.
- 1,200 lb maximum load capacity
- Bronze bushing sleeves for smooth rotation
- Volcano knurling pattern for secure grip
- Phosphate finish over 120,000 PSI steel
Who it's for
Fits home and garage gym lifters doing squats, bench press, deadlifts and Olympic-style lifts who want a durable bar without spending on a competition-grade model. Lifters who specifically want center knurling for max-effort squats should note this bar does not include it, based on one reviewer's comparison.
What buyers say
From Amazon customer reviews.
Reviewers repeatedly compared this bar favorably to models costing two to three times as much, praising the knurling feel and smooth sleeve rotation through squats, presses and cleans. One buyer who initially wanted a pricier bar with center knurling settled for this one and found no bars at their own gym actually had center knurling either, while another noted CAP had improved its shipping packaging after past scratch complaints.
Strengths and trade-offs
Drawn from this product's published specifications.
- Smooth sleeve rotation reduces wrist and forearm stress
- Knurling grips well without feeling overly aggressive
- Fits standard Olympic plates, racks and benches
- No center knurling, unlike some pricier bars
- Finish will show scratches with heavy use over time
Performance notes
Volcano-style knurling grips the palm without feeling as aggressive as a hard file, and the bronze bushing sleeves rotate smoothly enough that reviewers doing cleans and presses say wrist strain is noticeably reduced. Steel rated to 120,000 PSI tensile strength backs the 1,200 lb capacity, with a phosphate coating meant to slow rust while keeping the knurling texture intact.
