Surge Jump Rope - Our newest and most innovative ball-bearing design. Made specifically for athletes who want the best for speed and double-unders. Rubber handle grips keep hands comfortable and provides a sure grip. A favorite at CrossFit and other major fitness centers and fitness retailers.
The Science Behind The Surge Jump Rope
A jumper is trying to produce rotation in the handle’s axle. He does this by moving the handle in a circular motion with the cable trailing behind. This puts tension on the cable creating the centripetal force that causes it to rotate around the handle.
This motion permits the jumper to move her hands in more of a reciprocating (up and down) motion rather than a circular motion by implementing theories of a crank mechanism. It our belief that this causes less fatigue, can produce faster rotation, and allows the jumper to maintain a more consistent speed (assuming that maintaining a consistent pace in a reciprocating motion (like drumming) is easier than while in a circular motion).
The advantage to having two bearings is that it handles the axial load much more efficiently. With 1 bearing, there is the addition of detrimental axial torque. The added axial torque on the bearing will cause it to wear out faster, and adds friction so it spins less freely (by canting the inner race). Radial bearings are not designed with axial torque in mind. It is assumed that they will take only axial load and/or thrust load. A one bearing design, in my opinion, would at least need to have the addition of a bushing at the other end of the axle to prevent axial torque on the front bearing.
By putting the bearings as far away as possible from each other, the axial torque on the front bearing is optimally minimized (assuming your axle is rigid). Overall, the design makes the handle to be very rigid and feel ‘solid’ in your hand as opposed to the feeling of stress and torque you may feel in another design. We believe there are very few, if any, changes that could be made to the design of this rope that could reduce friction any more than it already does.
The Elite Surge Jump Rope is guaranteed for speed and with its patented dual ball bearing handles made from ultra light aluminium handles it has the capacity to to perform 7 spins per second.
The Elite Surge Jump Rope feels incredibly balanced when you use it. The machine cut aluminium handles feel very solid in your hands and help to give you more precision and control over the rope whilst jumping.
