Is this a true men’s Olympic bar (20kg / 28mm / 2200mm)?

Yes. The GravoMax Monkey King Bar 20kg (MKB20) follows the men’s Olympic profile: 20kg weight, 28mm shaft diameter, and 2200mm overall length.

What plates does it fit?

It fits standard Olympic plates and bumper plates with 50mm (2-inch) sleeve diameter.

Does it use bearings or bushings?

It uses a bearing-based rotation system for fast, smooth spin. Each sleeve includes needle bearings plus additional bushing support for stable rotation under load.

Is this bar suitable for Olympic lifts like snatch and clean & jerk?

Yes. The 28mm shaft and fast sleeve rotation are designed to suit Olympic weightlifting movements, including snatch and clean & jerk.

What is the load rating and tensile strength?

The bar is rated to 1500LB load capacity and uses spring steel with 200,000 PSI tensile strength.

What’s the difference between the 20kg men’s bar and a 15kg women’s bar?

The 20kg men’s bar follows men’s Olympic standards (20kg and 28mm shaft). A 15kg women’s bar is lighter and uses a smaller shaft diameter to match women’s Olympic specifications.

What finish does the bar have?

Both the shaft and sleeves use a hard chrome finish to support durability and a clean, professional look over time.

Elite Rotation and Unmatched Whip

We built the GravoMax Monkey King Bar 20KG for lifters who demand a true men’s Olympic feel. First, the advanced 8-bearing system keeps the sleeves moving incredibly fast and smoothly during turnover. Next, the precisely machined volcano knurl provides a secure grip without tearing your hands during high-rep sessions.

Because it uses premium spring steel, this bar delivers the perfect balance of stiffness and whip for explosive lifts. Ultimately, the full hard chrome finish ensures the bar stays clean and professional through years of punishing daily training in any commercial or garage gym.
