BREAKING RECORDS
Redefining Belt Performance with Carbon Power
A major upgrade to the classic lever action belt—engineered for lifters aiming to break new records.
Wide Buckle for Maximum Intra-Abdominal Pressure
The more intra-abdominal pressure you can generate during squats and deadlifts, the more stable and powerful your movements become.
To increase that pressure, a stronger belt lock is essential. A wider buckle provides greater surface contact and stronger fixation, resulting in more pressure and performance.
Nine-Pronged Clasp for Superior Lock and Adjustment
Simply widening the buckle isn’t enough. We’ve increased the thickness of the prongs and adopted a 3-row by 3-column (vertical × horizontal) layout.
You can choose from 3-prong, 6-prong, or 9-prong setups depending on the buckle position and the load you’re lifting. This not only allows you to fine-tune pressure levels but also maximizes fixation when using the full 9-prong setup—exceeding the performance of conventional wide buckles.
Lightweight Material Offsets Wide Buckle Drawbacks
Wide buckles are essential for high output, but they also add volume and weight.
Because the buckle sits in front of the belt, this forward weight distribution can affect your balance during lifts.
To counteract this, we’ve used lightweight carbon fiber to maintain power without compromising movement.
Smooth, Resilient Tightening Feel with Carbon Buckle
Unlike conventional metal buckles, the carbon buckle offers slight give during tightening.
This subtle resistance creates a uniquely smooth and premium feel not found in metal hardware.
Seamless Pin Design
The rotating pin is enclosed, preventing it from falling out due to wear and tear over time.
IPF Maximum Regulation Belt
Crafted from genuine leather to IPF max specs: 13mm thick, 10cm wide.
