Progressively wound springs have altered coil spacing to provide both a smooth ride and progressively firmer response to larger road irregularities and loads. Tighter coils respond to minor inputs providing soft initial fork travel, wider spaced coils offer greater resistance as tighter coils are fully compressed The best replacement springs for sporting applications as well as touring and general use.
