Overview
Not a plain beaded rope, the Sonic Boom M2 pairs silicone handles with an alloy steel cable on a swivel that spins freely. A self-locking design holds the cable without screws.
The reason to look at it is a speed and endurance rope with adjustable length and a screw-free build. The limitation is a thin listing, which gives no cable thickness and no detail on the spare cable.
Who it's for
Boxers, crossfitters and fitness users doing fast singles or double unders can adjust the length to fit. Absolute beginners who prefer a slower, heavier rope may find it too quick.
Pros and cons
- Slip resistant silicone grips
- Alloy steel cable
- Spare cable not described
- Cable thickness not listed
Performance notes
A steel cable spins with little air drag, so rope speed depends on wrist action and how well the swivel turns. Weight in the handles stabilizes each rotation, and trimming the cable to the user's height controls where the rope clears the floor.
