From Ride Engine:

During the early underground-days of the kitesurfing movement, riders were looking for more freedom in movement to allow more aggressive directional changes and easier toe-side riding. Their solution? The rope spreader bar. Now freeriders and hydrofoiling fanatics have joined kitesurfers in hyping the virtues of the rope spreader bar. The Unity Rope Conversion Kit easily transforms your fixed kite hook to rope while retaining all the benefits of the Unity Spreader Bar.

Features:

• Dual-rope system offers a full range of freedom that can be dialed into your preference of feel: setup as either full-sliding or with a mini-loop.
• High-grade Dyneema® rope with flying-line core for added safety.
• Stainless steel ring for friction-free movement.
