DO THE SPRINGFREE™ TRAMPOLINE RODS TWIST?
At first glance it looks as if the Springfree™ Trampoline rods would twist during a bounce. In fact the effect is undetectable in normal use. Springfree’s patented composite rods are designed to work in unison, to bend inwards as a jumper bounces, with about 0.3 of a degree of twist. This equates to ~5mm movement in a lateral direction, i.e. sideways/rotationally at the edge of the mat surface. All other movement is “axial”, or inwards, towards the center of the mat. Heavier jumpers (upwards of 85kg) will generate more axial movement, but little to no more lateral/rotational movement at the mat edge. Lighter jumpers generate less of both types. springfree’s patented composite rods are incredibly strong (stronger than steel in this installation) and in fact with the new Airbus 380 jet exterior made from a composite compound, we believe we’re in good class.
