Ninja NS392 Wire Speed Skipping Rope utilizes a 4mm steel wire core for high-velocity rotation. A 3-meter adjustable cable accommodates various user heights during cardio training. This iteration upgrades the NS391 by introducing ball bearings and a reinforced steel core instead of standard PVC.
Key Features
- Ball Bearing System: 360-degree high-speed rotation mechanism. Minimizes friction to prevent tangling during rapid double-unders.
- Steel Wire Core: 4mm diameter with PVC coating. Resists abrasion on rough concrete or dusty outdoor floors.
- Adjustable 3m Length: Integrated screw-locking sizing mechanism. Resizes the cable for different heights in under a minute.
- Ergonomic ABS Handles: 16cm length with non-slip texture. Maintains grip stability despite heavy sweat and humidity.
