Session4 Speed Rope
The Session4 is the ultimate speed rope for high-intensity functional fitness, utilizing a dual-bearing system that provides nearly frictionless rotation. Its knurled aluminum handles offer a superior grip even during high-sweat workouts, making it a favorite for competitive CrossFit athletes.
Quality & Materials
Handles are machined from 100% aircraft-grade aluminum. The rope utilizes a 3/32" coated cable that balances speed with enough feedback for the jumper to feel the rope's position.
Evidence & Testing
This rope has been used to set multiple world records in speed jumping. It is the unofficial standard for competitive CrossFit athletes globally.
Brand Transparency
RPM is clear about their dual-bearing technology and material sourcing, though specific manufacturing facility locations are less publicized than US-centric brands like Rogue.
Value Assessment
At $65, this is a professional-grade tool that offers the best performance-to-price ratio for anyone serious about mastering double-unders.
Why Not Alternatives?
Most speed ropes use plastic handles or cheap bushings that overheat and seize during long sets of double-unders. The RPM Session4's patented internal swivel allows for much higher RPMs than the Rogue or WOD Nation alternatives.
