Overview
CAP's 2 inch Olympic barbell comes in 5, 6 and 7 foot lengths, with the 5 foot version rated to a 500 lb capacity. It uses volcano style knurling and bronze bushing sleeves, built from steel with a 100,000 PSI tensile strength rating and a phosphate finish.
The shorter 5 foot length and lighter starting weight target beginner lifters, younger athletes or home gyms with limited space, rather than max effort loading. Bronze bushings rather than needle bearings handle sleeve rotation, which is common on entry to mid level bars and trades some smoothness for a lower price. The sleeves fit standard 2 inch Olympic plates and standard racks, benches and home gym equipment.
- 2 inch Olympic sleeve diameter
- 5, 6 and 7 foot length options
- Bronze bushing sleeve rotation
- 100,000 PSI tensile steel with phosphate finish
Who it's for
Works for beginner to intermediate lifters and home gyms wanting a compact Olympic bar for squats, presses, rows and general strength training. Competitive powerlifters loading near or past the bar's rated capacity should look at a bar built and rated for that load.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fits standard 2 inch Olympic plates and racks
- Bronze bushing sleeves rotate during lifts
- Volcano knurling for grip without excess sharpness
- Available in 5, 6 and 7 foot lengths
- Bushing sleeves rotate less smoothly than needle bearing bars
- 500 lb capacity on the 5 foot version limits it for advanced lifters
Performance notes
Bronze bushing sleeves let the sleeves rotate during cleans, presses and rows, which is meant to reduce wrist and forearm strain compared to a fixed sleeve bar. Volcano knurling gives grip without being sharp enough to tear hands during high rep sets, and the phosphate finish is meant to resist wear on the shaft.
