Session4 Speed Rope
The Session4 is the gold standard for CrossFit and high-intensity speed work, featuring a dual-bearing system that provides near-zero friction. Its 100% precision-machined aluminum handles offer a perfect balance of lightweight speed and extreme durability.
Quality & Materials
Handles are crafted from 100% aircraft-grade aluminum with a knurled grip. Cables are 3/32" coated steel, optimized for speed and aerodynamic efficiency.
Evidence & Testing
The rope of choice for multiple CrossFit Games champions. Engineering focuses on a patented dual-axis rotation system that reduces torque on the cable.
Brand Transparency
Detailed specifications on bearing types and handle weight are available, though specific manufacturing plant locations are less publicized than Crossrope.
Value Assessment
At $65, it is a professional-grade tool that outlasts plastic speed ropes by years. The replacement cables are affordable and easy to install.
Why Not Alternatives?
Competitors often use plastic handles that crack during high-impact drops or single-bearing systems that 'catch' at high RPMs. The RPM dual-axis rotation allows the cable to move freely in all directions, preventing the kinking common in fixed-head ropes.
