Overview
The RPM Speed Rope 4.0 (also known as the "Session Rope") is a high-performance speed rope engineered for extreme precision. Known for its patented Dual Axis Rotation, it is designed to eliminate torque build-up and provide a smoother, faster spin. The 4.0 model is lighter than previous versions and features a reinforced stem for increased durability during high-intensity workouts.
Key Features & Specifications
Handle Material: 100% precision-machined Aluminum with standard knurling for a secure, non-slip grip.
Rotation System: Patented Dual Axis Rotation and a NEW Dual Bearing System for friction-free movement.
Handle Length: 5.75” handles.
Cable: 12-foot Clear Coated 3/32" cable (standard). Note: Compatible with bare steel cables.
Portability: Includes a microfiber carrying bag for storage and transport.
Durability: Features a reinforced stem for added strength at the handle-to-cable connection point.
Sizing and Adjustment Instructions
The RPM Speed Rope 4.0 is highly adjustable but requires a specific setup to ensure the "Dual Axis" mechanism works correctly.
Measure: Stand on the center of the cable with one foot.
Position: Pull handles up to your chest. For most athletes, the top of the handle should reach the armpit level.
Adjust: Slide the adjustable set screws to the desired length.
Lock: Use the locking set screws to secure the handle-cable connection.
Trim: Use wire cutters to trim the excess cable. Important: Leave approximately 1–2 inches of cable beyond the screw to allow for future adjustments, then replace the end caps.
Maintenance and Surface Recommendations
Surface: The clear coated cable is versatile, but for the longest lifespan, use it on rubber gym mats or smooth indoor surfaces.
Bare Steel Option: If using the optional bare steel cable, it should only be used on smooth surfaces to prevent immediate fraying.
Cleaning: Wipe handles and cable with a damp microfiber cloth after use to remove chalk and sweat.
Storage: Always use the included microfiber bag. Avoid kinking the cable, as "memory" in the wire can disrupt the rotation arc.
Frequently Asked Questions (FAQ)
Q: What is the difference between the Session 4.0 and the Competition (Comp) 4.0?
A: The Session 4.0 (this model) is the "workhorse" designed for daily use and features standard knurling and a coated cable. The RPM Comp Rope 4.0 is even lighter, features more aggressive knurling, and comes standard with an uncoated bare steel cable for maximum speed.
Q: Can I use bare steel cables with the Session 4.0 handles?
A: Yes, the Session 4.0 handles are fully compatible with RPM Bare Steel Replacement Cables.
Q: Why is my cable fraying?
A: Fraying usually occurs from use on abrasive surfaces like concrete or asphalt. If the coating is worn through, the cable should be replaced immediately for safety.
Q: My bearings feel stiff. What should I do?
A: Ensure the set screws are not over-tightened against the bearing housing and that the stem is free of debris. The dual bearing system is designed for high-speed use and generally does not require lubrication.
