The MonoSpring Fork (MSF) is a revolutionary front fork, preserving the conventional fork behavior yet improving its characteristics in many respects. The single coil spring has a wire diameter/thickness ratio much more favorable in terms of spring dynamics; it can also be easily replaced to change the suspension stiffness (‘k’). Undisturbed by internal springs, hydraulics can use larger pistons and work free of friction; moreover, H-shaped beams can take the place of the springs, which lead to a lateral stiffness different (generally lower) than the longitudinal one. Last, but not least, the MSF scheme reduces the unsprung masses.
