Zero Friction Progressive Fork Springs give you the best of both worlds. They have an initial rate that provides a soft, compliant ride over small bumps, and a higher rate as the fork compresses to control nose dive and prevent bottoming. Each spring set comes with recommendations for fork oil viscosity and air chamber volume.
